performance.

Always turn the Volume to minimum, switch to another input or

turn the 851N off before plugging/unplugging cables to the USB

input or whilst booting up/shutting down your PC/Mac.

Ground lift switch

The Ground Lift Switch enables the USB interface earth to be disconnected from

the 851N chassis earth. Disconnecting (lifting) the earth can be useful if electronic

hum is heard through the speakers. The switch should otherwise be left in the

Ground position.

9. RS232C Interface

The RS232C interface enables external serial control of the 851N in custom

installation applications. A command set is available on the Cambridge Audio

website at www.cambridgeaudio.com. The RS232 interface can also be used by

Cambridge Audio service personnel for software updates.

10. IR (Infra Red) Emitter In

A 3.5mm mini-jack socket that enables modulated IR commands from multi-room

or IR repeater systems to be received by the 851N.

Note: Commands received by the IR Emitter In socket are not looped out of the

Control Bus. Refer to the ‘Custom Installation’ section for more information.

11. Control Bus

In – An RCA phono socket that enables un-modulated commands from multi-rooms

systems or other components to be received by the 851N.

Out – An RCA phono socket that provides control bus output commands for further

downstream units. This can be useful if using the iPhone/Android app to control

the volume on an Azur ampliers.

12. AES/EBU Balanced

In – For sources with a balanced (AES/EBU) digital output. This input is suitable for

16-24 bit content up to 192kHz.

Out – For external devices incorporating a balanced (AES/EBU) digital input.

Front panel controls

1. USB

Use to connect a USB storage device or another portable device containing music

les. 1A maximum current consumption.

Note: This USB port is not intended for connection to Apple mobile devices, no

functionality, charging or otherwise is supported.

2. Standby/On

Switches the unit on or off. When powering up, LED will ash approximately once

a second as the unit boots up, the display will initially be blank before a splash

screen appears.

Note that the full startup sequence can take approximately 30 seconds to complete.

Instant On

To enable Instant On, it must rst be activated within the setup menus. Go to

"Settings -> Power-> Instant On" and set to "On".

Instant On, when enabled, allows 851N to enter a lower power suspended state

using the Standby/On button. The display is turned off and many of the internal

processes are disabled to reduce power consumption. However the difference

between Instant On and Standby is that in Instant On, power remains connected to

the main controller, Ethernet and Wi-Fi sections.

In Instant On, networking functionality remains alive in the background. This means

that 851N can be quickly woken up out of the suspended state into an operational

state using not only the front panel, the infra-red remote and the control bus, but

also the Stream Magic App running on iOS or Android devices. This is not possible

when the unit is in full Standby mode.

Short presses of the Standby/On button then toggle the 851N between On and

Instant On.

Note: after putting the unit into Instant On mode, you will not be able to wake the

unit into full On mode until 5 seconds have elapsed.

Full standby can still be activated by keeping the Standby/On button pressed for

more than two seconds. A subsequent press of Standby/On turns the unit fully on,

but remember that this can’t be done over the network (i.e. from the iOS app) and

that it takes longer to reach the full operational state.

3. (i) Info

Pressing this button toggles between 'Now Playing' screen and the different 'Now

Playing' views.

4. Home

Press takes you to Home screen.

5. Filter

Press to toggle through three alternative digital lter characteristics: Linear Phase,

Minimum Phase or Steep. Alternative digital lters can offer subtly different sound

quality characteristics. The currently selected lter is displayed by the indicators

just above the button.

Phase

Press and hold the Filter/Phase select button for approximately two seconds to

select normal or inverted phase output. When the LED lights up, the phase is

inverted by the 851N.

If you suspect that your source material or amplier, etc., is inverting the phase

of the musical signal, you can use this function to re-invert the audio and regain

absolute positive phase.

6. Infrared sensor

Receive IR commands from the supplied remote control. A clear unobstructed line

of sight between the remote control and the sensor is required.

7. (More)

When playing media over UPnP or USB drive, more will show the queue.

For Internet Radio and Streaming Services this will allow access to any interactive

services or options.

8. Display

Displays the status of the unit.

9. Play/Pause

Plays and pauses playback.

10. Stop/Delete

Press during playback to stop or press in various menus to delete the present item.

11. Skip

Press once to skip forwards or backwards one track.

12. Navigation/Select (rotary dial)

Rotate to scroll and navigate around the menus. Pressing the rotary dial in performs

the 'Select' function to accept the item/function shown on the display.

Fast Scroll feature

When scrolling through lists of tracks or stations, normally rotating the rotary

encoder or press of the remote control navigator button steps to the next item in

the list. For long lists this can become tiresome.

The Fast Scroll feature, which is always enabled, detects how fast the front panel

rotary encoder is being rotated or how long the remote control navigator buttons

have been pressed. The faster the encoder rotation or the longer the button press,

the bigger the jump up or down the list with each step.

If navigating using the front panel rotary encoder, reducing the speed of rotation

then decreases the step size again.

If navigating using the remote control, you need to release the button to stop the

scroll and press-and-hold the button again to begin the scroll speed ramp-up, or

single-press the button to step one item in the list at a time.

13. Return

Press to return to the previous menu.

Basic connections

Network connections

Before you can use your 851N for Radio/Streaming you must have the following:

• A broadband internet connection (such as ADSL) to a suitable internet service

provider (ISP).

• A network connection either wirelessly via 802.11b/g or n Wi-Fi or wired Ethernet

connection (10 or 100 M bits/sec via an RJ45 connection).

Note: For playback of high sample rate les (24-bits/176.4kHz & 24-bits/192kHz)

streamed from your home network, we recommend using an Ethernet connection

to avoid unwanted disruption as the high data rate of these les is beyond most

Wi-Fi networks capability.

In many cases the broadband modem, router and wireless access point will be a

single combined unit supplied by your Internet Service Provider or bought from a

computer store.

If your wireless network is congured to use Wired Equivalent Privacy (WEP) or Wi-Fi

Protected Access (WPA) data encryption then you will need to know your WEP or

WPA key so you can get the 851N to communicate with the network.

IMPORTANT:

Before you continue, make sure that your wireless access point or router is

powered up and working with your broadband internet service (use your computer

to verify this). To get this part of the system working you must read the instructions

supplied with the wireless access point or router.

The 851N can be congured to connect to a Wired or Wireless network or has

an (default) Auto setting. In Auto the 851N looks for a each connection type

and selects whichever is present. You can also force the unit to one or the other

connection type, see later Settings section.

Connecting to a wired network

Plug one end of a network cable (Category 5/5E straight through Ethernet cable)

into the LAN port on the back of the unit.

Note: Only connect the LAN port of the player to an Ethernet port that supports

10BASE-T or 100BASE-TX. Connecting to any other ports or jacks, such as a phone

jack, can damage the unit

The 851N should automatically connect to your network as below via DHCP; this

means it will be given an IP address by your router automatically.

The 851N is able to receive and play back media from several distinct types of

source. Here we have attempted to give an overview of the various types of service

available and the terminology you may encounter.

Internet Radio

These are ‘radio’ stations broadcast over the internet. Currently the StreamMagic

range can access about 20,000 internet radio stations all sorted by us into

Location, Language and Genre. The list of available stations is constantly

maintained and automatically updated to your unit via the internet. If you register

on the StreamMagic website (www.stream-magic.com) you will also be able to

browse the stations and set presets on your units from your PC.

You can also add stations to your units that are currently not in the Stream Magic's

Radio database, suggest new stations to us and more. There are also links and

help for setting up third-party Streaming Services from a wide variety of other

suppliers. Other Stream Magic features will be launched in the future, check the

website from time to time to see the latest developments.

Streaming Services

Streaming Services are similar to Internet Radio but come from other suppliers and

often have an element of interaction with the user. Because Streaming Services

generally allow the user some choice over the content they listen to, they are also

licensed differently to iRadio by the music companies and often each service only

has arrangements in certain countries and may also charge a subscription for

membership.

Examples of such services are Aupeo!, Pandora, Rhapsody, SIRIUS/XM, Live365

and others. All allow some control of the content from 'play me something that

sounds like U2' to the ability to select and play whole albums of your choice. Some

also offer the ability to download content for use off-line as well.

The 851N supports many of these services, navigate to Streaming Services on

the unit for a list or even better check out our website at www.stream-magic.com

for more details of which services are available in your area, what they do and

how to sign up. These services come from third parties and although we support

connections to them they do not come from us and we are not responsible for their

service in any way. Your account will be with the service, we are merely acting as

a website to make the connection simpler and more convenient plus we support

the correct software on our unit to allow playback and browsing of their content.

Network Media

The 851N supports a wide range of compressed formats; MP3, AAC, WMA and Ogg

Vorbis CODEC types are all supported, plus for true audiophile use it also supports

either uncompressed PCM (in a WAV container) or losslessly compressed FLAC,

both can contain from 16-bits/44.1kHz from CDs right up to 24-bit/192kHz for

better than CD quality from suitable download sites.

Note: For this to work your server will also need to support the CODEC you wish to

play as some have limitations and may not serve FLAC for instance. Always check

that the server you wish to use also supports your favoured CODECs.

Also for lossless/uncompressed formats both the server and network connection

will need to sustain the high bitrate necessary.

Note: It is not recommended to use Wi-Fi connections for content above 24bits,

96kHz if lossless/uncompressed.

USB Media

The 851N also supports USB Media from USB Flash-disks or USB hard-drives and

has 4 USB 2.0 ports for this purpose. Here the 851N simply browses the folders

present on the media attached and displays them. Only content that the 851N can

play will be shown. This feature is provided for convenient access to temporary

storage devices.

It is however highly recommended that UPnP is used for continued use of stored

media as the UPnP system is able to support album art, sophisticated content

browsing and ltering and other features not possible with simple folder browsing.

Note: Supports NTFS and FAT32 le system.

Podcasts

Podcasts are archived audio recordings downloadable over the internet. Often

podcasts are recordings of previous live broadcasts or episodic content.

The 851N supports various third party podcast services, navigate to Podcasts

on the unit for the list available in your area. In addition the 851N supports your

own personal choice of podcasts where you know its URL (weblink) via the Stream

Magic website, see later section.

Overview Getting connected

851N/Amplier

Broadband Router/Modem

Internet

Ethernet cable

Connecting to a wireless network

Place the 851N in range of your wireless network (usually 10-30m of a suitable

wireless transmitter, although this is affected by walls and the construction of your

building) and turn it on, via the back panel switch and then on the front panel.

The 851N will automatically connect and obtain an IP address from your wireless

network. For advanced users, if you would like to give your 851N a static IP address,

then see the 'Network cong' section of the manual.

Note: If you make a mistake at any point, you can always press the button to go

back to the previous screen.

The unit will now scan for all available wireless networks and will display "Scanning".

If it can’t nd one then the display will say: "No Wireless Networks Found". If this

happens then you need to either move the 851N nearer your wireless access point

or investigate any issues with your wireless network.

When the 851N nds your wireless network, it displays the broadcast name (ESSID)

for the access point – this is a name allocated to the access point by whoever set

up the network, it may either be a default name for your router/wireless or may be

a more familiar name such as "Johns Wi-Fi" etc. If your 851N nds more than one

wireless network you can simply choose which one you want to connect to. Turn the

rotary dial to see the ESSID for each wireless network.

When the ESSID for the wireless network you want to connect to is displayed on

the screen, press the SELECT button. If your network is not congured with an

encryption code, the screen should say "Connecting to network" then "Network OK".

If the screen displays either "Enter WEP key" or "Enter WPA key", then the network

is using one of the supported encryption systems: Wired Equivalent Privacy (WEP)

or Wi-Fi Protected Access (WPA). You now need to enter your correct WEP or WPA

code. The person who set up the wireless network in the rst place will know what

this code is (or be able to reset it to a new known code); if that person is not you,

then you need to nd out what it is.

After 3 seconds, the display goes into the code entry mode. To enter the code, use

the rotary dial to select each character of the code in turn, pressing the SELECT

button after entering each character.

Note: The WEP and WPA codes are case sensitive, so you must enter them exactly.

After entering the nal character, use the rotary dial to select the character and

press the SELECT button. It’s a little ddly but you will only need to do this once. The

851N will remember this code and use it automatically from now on.

The unit should now be able to connect to the network.

Note: We recommend rebooting your 851N to search for any rmware updates, as

new rmware may have been released since your unit was manufactured.

The 851N home menu consists of 5 items:

Presets

Radio

Music Library

Inputs

Settings

These allow access to the four basic types of media choice plus a Settings menu

for the unit.

You can return to this menu at any time by pressing the button.

Simply scroll through the items with the scroll wheel or ▲▼◄► navigator buttons

on the remote control and press in the scroll wheel or use the Enter/Mode button

on the remote to select the item you want.

Presets

The 851N supports presets. These can be Internet Radio stations or streams from

most Streaming Services. UPnP/USB Media cannot be set as a preset. To add a

station/stream to a preset, rst select that stream for playback in the normal way.

Now press the 'Home' button on the remote and navigate to the Presets menu.

Note: Empty presets are not displayed. To save a presets to an empty location,

select 'Set Preset' and all slots will be displayed.

Select the preset location you require and press the Navigation/Select dial or the

Enter/Mode button on the remote to save the current station/stream to that preset.

Recalling presets is done simply by selecting the Presets button on the remote or

via the Home menu.

Note:

– The 851N loads the presets for display from our Stream Magic servers over the

internet, thus they can take a few seconds to appear.

– All saved Presets will be deleted when a unit is registered/re-registered online.

Radio

The Stream Magic Internet Radio service brings thousands of internet radio

stations to you. The sheer choice available on the internet allows you to nd new

music, listen to stations in your native language (or perhaps if you are learning

another one), from your home town or by your Genre of choice.

It has to be said that the audio quality of internet radio varies greatly dependant

on the bitrate and compression technology used by the broadcaster, but the choice

more than makes up for this. Internet Radio allows you to explore and nd new

music from all over the world.

Note: As an 'aggregator' service we are simply organising the browsing and

connection process for these stations so that you don’t have to manually search for

them or type in any URLs (web links) etc to access them. Whilst we regularly check

the stations to make sure they are still transmitting reliably and in reasonable

quality, we are not responsible for their content in any way.

As well as the thousands of stations we offer, if you want to listen to a particular

station that is not included in our service you can add it via the Stream Magic

website at www.stream-magic.com, see later section. You can also visit the

www.stream-magic.com website and put in a request suggesting new stations for

us to add to the service. We welcome your feedback.

It is not necessary to register your 851N to use the free Stream Magic Internet

Radio service but by registering you will be able to edit settings on your 851N via

the website, manage your presets, set up new 3rd party Streaming Services and

more.

How to use Radio

Location – Enables you to choose from the stations in any of the countries which

you choose from a list.

Genre – Enables you to choose radio stations according to their declared content,

for example Classic Rock, Sport, News, etc.

Search Radio Stations– Enables you to search for a station you know the name of.

Enter the full name or rst part of the name for your desired station. The 851N will

bring up a list of all stations that contain a word that starts with your search term.

Note: Although we check the stations for continuity of service, some radio stations

do not broadcast 24 hours per day, and some stations may not always be on-line.

Streaming Services – The services available vary depending on your geographical

location. Because Streaming Services generally allow the user some choice over

the content they listen to they are licensed differently to iRadio by the music

companies and often each service only has arrangements is certain countries.

When you enter this menu the ones that are available to you in your country will be

shown. Those that are free to use or have a free to use version will work 'straight

out of the box' Others will guide you to the relevant sign up page, should you so

wish.

For more details on what these services offer, please go to our www.stream-magic.

com website, links to each service can also be found here and you can prevent

services appearing in this menu that you do not wish to sign up to.

Podcasts – The podcast services in your area will be shown. These typically allow

you to choose different types of podcast by subject, date or perhaps popularity etc.

It is important to understand that the menu structure here is coming from that

service and is controlled by them. It may therefore change as the service updates

its features etc.

Note: To use the Personal Podcasts feature, sign up at www.stream-magic.com

and enter the URLs of podcasts you’d like the 851N to automatically sync to. This

feature allows you to access podcast on the 851N that are not available in the

Podcasts services we support.

Registering your 851N with the Stream

Magic website

To access extra features on your 851N such as linking premium streaming services

to your 851N, adding non-Stream Magic internet radio stations or simply editing,

copying, re-ordering or deleting presets rst you will need to set up a free account

with Stream Magic.

Open www.stream-magic.com from an Internet browser. Click on the 'Register' link

and follow the on-screen instructions to set up an account and to link your 851N to

this new account by entering your 851N's seven digit registration code, which can

be found in the 'Settings > Get Registration Key' menu of the 851N itself.

This is a unique key code generated by the unit during the registration process.

Note: The key lasts for about 10 minutes, if you don’t use it in that time you will

need to exit and re-enter this menu to get a new key.

Your 851N is now registered and you can use the website to manage your presets,

Podcasts and more. You can also suggest new stations to us, setup 3rd party

Streaming Services and view information from us on new products.

After creating and logging into your new account, you can now add, remove or re-

order presets on your 851N from the 'Presets' tab.

There is also an enhanced internet radio station search facility, allowing you to

search for stations by minimum bit rate, etc and also the facility to add non-Stream

Magic internet radio stations as presets if you know the station’s URL.

To add further Stream Magic products to your existing Stream Magic account

(perhaps you want a second or third Stream Magic in a different room) then this

can be done by accessing the ‘Players’ tab in Stream Magic and clicking on the

‘Add a player’ link.

You can then choose to copy all or some of the existing presets from your current

Stream Magic to the new one.

Note: You can register as many products as you like and manage the presets etc.

across several products which could be in different parts of the world all seamlessly

from your Stream Magic website.

Music Library

The 851N can access media from UPnP/DLNA Servers or USB Media connected

via USB. The 851N displays the following submenus:

UPnP is by far the preferred method as it allows for browsing by artist, album and

other methods, has support for control from Wi-Fi controller and the media can be

shared amongst several devices.

UPnP servers

Your 851N can connect with Computers or Network Attached Storage devices that

feature a Universal Plug and Play (UPnP) AV Server.

When using a UPnP server to share your media, the search and selection criteria

are determined by the server and not the 851N, but typically include Album, Artist

and additional options such as Genre.

As long as the 851N is correctly congured for your Network, it will automatically

discover and connect to UPnP servers it nds. It will then allow navigation of the

menu structure coming from that server.

There are many suitable UPnP server software packages available for PC and Mac.

Stand-alone servers and Network Attached Storage (NAS) devices with built in

UPnP server capabilities are also available. Please see the set-up guides on our

website at http://support.cambridgeaudio.com/.

Once you have setup a suitable server, navigate to the My Library menu and press

Select.

The 851N will perform a scan of your network and report any UPnP Servers it nds.

If none are found it will display "No Servers Found" on the display. If a server or

servers are found, UPnP server names will be displayed and you can select which

one you’d like to get the contents from.

Select the server you want and the 851N will then load the appropriate menu

structure from that server. These typically allows you to browse the content by

Album, Artist, Genre etc. It is important to understand that the menu structure

here is coming from the server and not the 851N.

You can now browse and select any music content in a format the 851N supports

(currently AAC, MP3, WMA, AIFF, FLAC, WAV and Ogg Vorbis).

Note: Not all servers support serving of all these formats. Always make sure the

server you choose also supports your formats of choice. For example, Windows

Media Server does not currently serve FLAC format.

Alphanumeric Search

This is a search function menu inserted by the 851N into the browse tree of UPnP

servers that support an external search function.

Where available you can select Alphanumeric search and then enter the name or

partial name of an album or track you wish to nd.

Simply select each character in order using the Navigation/Select dial or the

▲▼◄► buttons on the remote, using the dial, rotate to each character and then

press in to select or press the Enter/Mode button on the remote. You can also use

the button to enter a character and the button to delete a character.

Once nished either press the button or navigate to the symbol and press

the Enter/Mode button on the remote or press the Navigation/Select dial.

The 851N then displays all Album names or Track names it can nd that matches

your chosen text.

You can then simply select your chosen item and press the Enter/Mode or

button on the remote to start it playing.

The 'Now Playing' screen

Selecting a new Station, Stream or Media item will start playback and display the

'Now Playing' screen.

The current Artist/Album and Track or Station name will be shown with the relevant

CODEC details (i.e. audio le type and bitrate/sample rate.)

For Media les, the 851N also shows the incremental track playback time.

You can also display the now playing screen at any time by pressing the ibutton on

the remote control or front panel.

Random

Accessed via the remote or Stream Magic app only. Press the Random button to

toggle Random On or Off.

The 851N displays a in the 'Now Playing' screen when Random is On.

If the currently selected media item/folder contains fewer than 1000 tracks the

851N generates a true random shufe of those tracks and starts playback such

that all are played once in a random order and then playback stops.

If more than 1000 tracks are contained the 851N will instead pick a track at

random for playback then pick another one randomly (and without reference to

what has gone before) once the current one has nished.

This continues until Random is turned Off. Thus for >1000 tracks the playback of

any track may be repeated randomly.

Repeat

Accessed via the remote or Stream Magic app only. Press the Repeat button to

toggle Repeat On or Off.

If the currently selected media item is a track the 851N will repeat that track, if it is

an album or artist etc. the 851N will repeat all tracks in that item.

The 851N displays a in the 'Now Playing' screen when Repeat is On.

USB Media

The 851N can also playback audio content from standard USB hard-drives and

thumb drives. Simply copy your media les onto your USB drive and then connect it

to the front or back USB sockets of the unit.

Press the Home button to get to the top menu. Select the 'Music Library' menu.

The 851N will now scan the thumb drive for media les. Once the scan is completed,

you will then be able to browse the les by selecting 'By Album' or 'By Artist'.

Queue

Viewing the queue

To view the queue at any time press the '•••' (more) button. You can jump playback

to any point in the queue by navigating up/down the list and pressing the Enter

button.

Editing the queue

Tracks can be removed from the queue by highlighting them with the navigator and

pressing the Stop button.

To clear an entire queue, navigate to the bottom of the queue to highlight [Clear

Queue] and press the Enter button.

Note: Switching the 851N into standby will delete the queue, unless Standby Mode

is set to 'Network Standby'.

Playlist

The 851N also supports various playlist formats. For permanent storage of favourite

media selections it is recommended to use suitable software to create playlist.

These can then be accessed by the 851N from USB Media or UPnP servers that

support Playlist serving.

Inputs

»USB Audio

»D1-D5 (S/PDIF Coax / Toslink Optical)

»Bluetooth (Only available when a BT100 is plugged into the rear USB)

»Spotify

The 851N has 6 digital inputs, USB Audio, S/P DIF co-axial and Toslink optical.

The digital inputs allow you to play audio sent from a separate digital audio source

such as a PC or CD player with digital outputs. This can optimise sound quality, for

example where the 851N USB Audio is used instead of the PC soundcard or the

upsampled and re-clocked low jitter DACs of the 851N are used instead of a CD

player DACs.

The USB Audio input directly connects to a PC or Mac computer. The 851N

can be setup to stream via the simple setup USB1.1 or the high sample rate

24-bit/192kHz via USB2.0. Also note that the SP DIF co-axial and Toslink inputs

are capable of high sample rates up to 24-bit/192kHz, but your source equipment

and interconnect cables must be capable of this sample rate to achieve this.

Advanced USB audio

The 851N is both USB 2.0 (Hi-Speed) and USB 1.1 (Full-speed) USB port compatible.

It should also work with the new USB 3.0 ports where the PC will simply treat the

851N as if it were a USB 2.0 or 1.1 device.

The 851N also supports two USB Audio protocols (not the same as the port types

themselves) USB Audio 1.0 (which works over USB 1.1 ports and supports up to

24-bit/96kHz) or USB Audio 2.0 (which requires a USB 2.0 port and can support

up to 24-bit/192kHz).

The default conguration is USB 1.1 and USB Audio 1.0 which works with nearly all

common operating systems and computer types without drivers and supports up

to 24-bit/96kHz audio, simply plug in and play.

In this conguration the 851N is able to work at up to 24-bit/96kHz by declaring to

your computer that it can handle any sample rate from 32kHz to 96kHz.

However in some Windows/Mac operating system variants the operating system

itself may restrict or x the output sample rate or re-sample the audio.

For more details on USB Audio, see our online guide at www.cambridgeaudio.com.

The USB driver is also available from the website. With careful choice of playback

software and settings many pitfalls can be avoided.

In particular our free Windows USB Audio 2.0 driver (available from our website)

supports up to 24-bit/192kHz audio and WASAPI Exclusive or ASIO modes that can

give enhanced performance.

A brief explanation of your choices are below:

Use with PCs

With the 851N switched to USB Audio 1.0 (this is the default setting) the 851N will

work with the native Windows XP, Vista, Windows 7 or 8 Audio 1.0 driver (no need

to load any new driver) and accept audio up to 24-bit/96kHz.

With the 851N switched to USB Audio 2.0 the 851N needs the Cambridge Audio

USB Audio 2.0 Driver to be loaded and can then accept up to 24-bit/192kHz (and

support ASIO and WASAPI Exclusive if required).

The driver is available from www.cambridgeaudio.com.

Use with Macs

No extra drivers are required. With the 851N switched to USB Audio 1.0 the 851N

will work with the native Mac OS-X 10.5 (Leopard) or above Audio 1.0 driver and

accept audio up to 24-bit/96kHz.

With the 851N switched to USB Audio 2.0 the 851N works with the native Mac

OS-X 10.5 (Leopard) or above Audio 2.0 driver and can accept audio up to

24-bit/192kHz.

Use with Linux

In USB Audio 1.0 mode the 851N will work with most Linux distributions, allowing

the playback of audio up to 24-bit/96kHz.

Newer Linux distributions (e.g. Ubuntu 10.04) support USB Audio 2.0 for which the

851N should be switched to USB Audio 2.0 to accept audio up to 24-bit/192kHz.

For both cases because Linux distributions vary according to their creators' choice

of software components, including drivers, it is not possible to guarantee operation

and Audio drivers may need to be loaded.

‘Class drivers’ for generic support of USB Audio Class 1.0 or USB Audio Class 2.0

devices may be available from the Linux community, we do not supply these.

BT100 and Bluetooth audio streaming

The 851N is compatible with the optional BT100 Bluetooth adaptor from

Cambridge Audio.

When a BT100 is plugged into the rear USB socket an extra menu item called

Bluetooth appears in the Digital Inputs menu.

Selecting this allows the 851N to receive wireless Bluetooth audio from most

phones/tablets and laptops.

Both the standard SBC CODEC and newer high quality aptX CODEC are supported

(if the sending device supports it). Contact your dealer for details.

Optional BT100 Bluetooth adaptor

When connected to your 851N this adaptor allows the 851N to receive Bluetooth

Audio (known as Bluetooth Advanced Audio Distribution Prole or A2DP). Contact

your dealer for details.

The BT100 supports Bluetooth A2DP using either the original SBC encoded form or

the latest higher quality aptX encoded form.

SBC and aptX refer to the encoding used over the wireless Bluetooth interface only

and not the format your music may be in, which can be any type that your phone/

laptop or other playing device supports.

Your playing device plays your les then re-encodes the playback before streaming

it to the BT100 in one of these two formats.

Many phones and laptops now feature Bluetooth with A2DP. SBC should be

supported by all such devices (it is the mandatory format for A2DP).

aptX is optional, so check if your sending device supports it, if you wish to achieve

the highest quality audio transfer.

Note: The BT100 declares that it can handle both SBC and aptX to the sending

device which will then use whichever version it supports.

851Nazur

What is aptX?

aptX is a high quality CODEC (CODer/DECoder) i.e. a way of compressing audio

data so it can be sent over a link such as Bluetooth then decompressed on the

other side (if both devices support it).

If your Bluetooth audio source does not support aptX, the BT100 will fall back to

using the standard SBC CODEC that is supported by all Bluetooth audio devices.

BT100 controls and connections

A. Pairing button/Status LED

Button performs pairing and related functionality. Integrated LED indicates BT100

status.

B. USB plug

Streams high quality USB audio into your 851N USB socket.

C. Extension cable

Allows the BT100 to be positioned for accessibility or optimal wireless reception.

Pairing

To begin streaming high quality music from your chosen media source it will rst

need to be paired with the BT100.

A. Insert BT100 into the USB port at the back of your 851N.

B. Wait a moment for the BT100 to be detected. Then double click the button to

enter pairing mode, the BT100 indicates it is in the pairing state by ashing

rapidly.

C. Put your Bluetooth compliant audio source into pairing mode. Please consult

your manufacturer’s user manual on how to do this.

Pairing your BT100 and source establishes an authorised audio link that can then

be used again in the future without having to go through this stage again.

After pairing you can just select the BT100 and play at any time as long as your

Bluetooth A2DP compatible source (phone/laptop etc.) is within approx. 10m of

the BT100.

Normally on your source you will need to select Bluetooth Pairing and then the

BT100 should appear as ‘Cambridge Audio BT100’ in a list of locally found

Bluetooth devices.

Select that item in the list to nish pairing.

D. On successful pairing, the BT100s LED goes off for a second or two, then triple

ashes quickly. The LED then goes off and only lights up in the future when you

are playing audio via Bluetooth.

E. To play back via a paired Bluetooth device, simply select the BT100 on that

device and start playing. The BT100 LED lights up constantly when streaming

SBC or on and icks off every 2 seconds when streaming aptX.

Notes:

– You can pair to more than one source up to a maximum of 8 sources at any

time. Pairing to a 9th device will cause the rst one to be forgotten and so on.

However as you would expect the BT100 can only play back from one of these

sources at a time.

– When you have nished playback many sources keep the Bluetooth link active for

a time unless you actively tell them to stop by deselecting playback via the BT100

(do not unpair as this is not necessary).

This can prevent another source to be able to access the BT100.

To immediately use another source, simply deselect the BT100 for playback on

your rst source device before starting up on a second.

– Some devices stream empty data all the time even when paused or stopped.

These devices will cause the BT100s LED to be on even if playback is currently

stopped or paused.

Get registration key

This will display a key that can be used to register your 851N on the Stream Magic

website at www.stream-magic.com. First you will need to set up an account on

Stream Magic. Open www.stream-magic.com from your Internet browser. See the

section earlier on Stream Magic registration.

Note:

– The generated key lasts for about 10 minutes, if you don’t use it in that time you

will need to exit and re-enter this menu to get a new key.

– All saved Presets will be deleted when a unit is registered/re-registered.

Network

This menu enables you to set your 851N’s network settings, scan again for a

connection to another wireless network, or to manually congure the network

parameters. This is useful if you move your 851N to a new location for instance.

By default the 851N will be set for Automatic wired/wireless detection and automatic

IP addressing (DHCP) which will work without setup in most circumstances (for Wi-

Fi you will need to enter your WEP/WPA key if you have one).

In Auto mode the 851N will look for a wired connection rst and then scan for

wireless connections if it doesn’t nd one. It will also try to obtain an IP address

automatically from your router/DHCP server.

If you wish to make changes to your setup the 851N displays the following

submenus.

»Scan for networks

»Enter network name

»Current Cong

»Edit Cong

»Wi-Fi Strength (only available if connected wirelessly)

»Signal Warning

»Wi-Fi Region

»Wired/Wireless

Note: All wireless related menu are only available if the wireless dongle is

connected to the unit.

Scan for networks

This option scans all available Wi-Fi frequencies for wireless networks and allows

you to connect to them.

The 851N can connect to 802.11b/g or n networks (2.4GHz frequency range only

for n networks).

A list of available networks will be presented. If a particular network requires an

encryption key, a symbol will be seen at the end of the network name.

Select your local network using the Navigation/Select dial and press it in for enter.

The 851N will then connect to the network using a saved key (if you have previously

set one) or present you with an alphanumeric entry menu. Here you can enter the

network key you set up when setting up your wireless network.

Select each character in turn using the Navigation/Select dial and then press

or navigate to the symbol and press Navigation/Select dial to enter that key. If

you make a mistake, press to go back one character.

The 851N can handle keys in WEP, WPA and WPA2 formats (the choice of format is

made by appropriate settings on your router) and automatically generates the right

format from your text according to the router request.

Settings menu

Enter the network name

This option allows the 851N to search for and connect to a particular network

name only.

Type your network name in using the alphanumeric entry screen.

If no matching network is found 'Network not found' will be displayed.

Current cong

This menu rstly displays the IP mode (static or dynamic). This will be Auto/DHCP

(i.e. dynamic, this is the default) or alternatively Static IP.

For either mode by turning the Navigation/Select dial the 851N will scroll through

the various current IP parameters, for instance the ESSID of the current wireless

network, Wired and Wireless MAC addresses, current IP address, (Sub)Netmask,

Gateway address etc.

Edit cong

This menu allows the selection of IP mode between static or dynamic (Auto/DHCP).

Auto/DHCP is recommended for most people in most circumstances. Static IP

requires quite a bit of knowledge about IP networks, and is for advanced users only.

The default setting is thus Auto/DHCP, here the 851N obtains its IP address each

time you switch in on by a process called DHCP which means it is different each

time it is acquired. This process is completely automatic and much simpler than

implementing Static IP.

However sometimes it is useful (especially in large networks) to know the exact IP

address of each device, this can only be done by using static IP.

When using Static IP you will also need to enter the network mask you wish to

use and the addresses of your gateway and DNS service, note there is no way for

Cambridge Audio to know what these are in your network. Only select static IP if you

know exactly what you are doing!

To set static IP, select the 'Settings > Network > Edit Cong' menu.

The 851N will now display 'Auto (DHCP)? YES/NO'. Turn the 851N’s rotary dial to

select 'NO' and then press SELECT.

You will now be able to enter the xed IP address you wish to give your 851N by

using the rotary dial to select the desired numbers followed by pressing Navigation/

Select dial to end inputting the address.

The 851N will now prompt you to enter the required network mask for the network.

You will be able to enter this in the same way as before for entering the IP address.

You will now need to enter the default gateway’s IP address used by the 851N on

the network.

Finally, you will need to enter the DNS IP address for the 851N. On some networks,

you may need to enter your ISP’s DNS IP address, which should be available on

your ISP’s support page on their website.

After entering the above information, the 851N will now try to connect to your

network. If you wish to use DHCP again simply select 'Settings > Network > Edit

Cong' and then set the 'Auto (DHCP)? YES/NO' to 'YES'.

Wi-Fi strength

Displays the strength of the received Wi-Fi Signal.

Note: If Wi-Fi has been turned off (Ethernet mode only) the signal strength will

show as 0%.

Signal warning

The 851N can display a warning if the Wi-Fi signal strength is low enough to be

causing reduced throughput. The options for the Signal Warning are simply Yes

or No.

Wi-Fi region

Different parts of the world use slightly different frequencies for Wi-Fi. For best

performance you should set the 851N to the region you live in, the current options

are US, Spain, Europe (i.e. other than Spain), Japan.

851Nazur

Wired/Wireless connection

It is possible to connect your 851N to your network via an available Ethernet

connection (RJ45) or via a Wi-Fi router. By default the unit is in AUTO mode, each

time you turn the unit it looks for the presence of a wired connection, and tries to

use this, if none is present or it cannot connect it then tries to use the wireless

connection and so on. In Auto mode once the 851N has established a certain type

of connection to the network, then this type of connection will remain in use while

the 851N is on.

You can alternatively congure the 851N to permanently only use the wired or

wireless connection from the 851N’s 'Network' menu, select 'Wired/Wireless'. This

menu will present you with three options: 'Auto', 'Wired Only' and 'Wireless Only'.

Selecting 'Wired Only' will cause the 851N to reboot and then only use its Ethernet

connection to communicate with the network. Selecting the 'Wireless Only' will

cause the 851N to reboot and only use its Wi-Fi connection. Selecting the 'Auto'

option means the 851N will try both and settle on the one it can make work as

described above.

Firmware

This menu item displays some hardware/software version numbers for your 851N.

Turn the rotary dial to scroll through the various items.

The Service Pack is the currently loaded rmware software. It’s a good idea to

note this down if you need to contact our technical support people as they may

request it.

The Serial Number and Product Code are not normally required by the technical

support team.

Note: This Serial Number is not the same as the physical serial number on the back

of the product itself.

»Check for updates

»Version

Check for updates

Use this option to download new rmware for the 851N from Cambridge Audio over

the Internet.

If you select this item the 851N will contact our server and see if a newer version of

software is available (‘Checking for updates’ will be shown in the display).

If new software is found the 851N will prompt you and ask if you want to download it

or not. It is a good idea to update the rmware from time to time to take advantage

of any bug xes or new features. At this stage, you can press the 851N’s button

to cancel the rmware upgrade. A Firmware upgrade may take several minutes.

Note:

– It is very important that once the Firmware upgrade has started you do not switch

off the power to the 851N until the operation is complete otherwise the 851N

may become permanently damaged.

– Also do not interrupt the network or internet connection by removing the Ethernet

lead or switching off your router etc.

Display brightness

Alters the brightness of the 851N display backlight. There are three brightness

levels; off, dim, bright and an option to switch-off the backlight.

When the display is set to OFF, nothing will be displayed onscreen until a selection

is made via the front panel or remote control. The display will then re-activate

allowing you to browse the menu and make your selection. The display will then

automatically switch back off after a few seconds if no further selections are made.

Device name

This menu allows the setting of the declared UPnP Client name for your 851N.

This is the name other UPnP devices (such as control points and remote apps etc.)

will display when they see the 851N.

The default name will be ‘851N’ but can be changed to any name you can easily

recall such as ‘Dads 851N’ or ‘Kitchen’ etc.

Audio

This menu contains a setup conguration as shown below.

»Digital Pre-amp Mode

»Balance (only available when digital pre-amp mode is enabled)

»USB Audio Class

Digital Pre-amp mode, when enabled, allows volume adjustment to be performed

within the up-sampling Digital Signal Processor (DSP) before being converted to an

analogue audio signal for connection to a power amp.

Normally, the output of 851N (and most other source components) is output at

"full-scale" (i.e. maximum volume). This signal is then fed into a pre-amp which is

used to control the volume of all audio sources connected to it.

To enable Digital Pre-Amp mode it must rst be activated within the setup menus.

Go to "Settings -> Audio -> Digital Pre-amp Mode" and set to "On". 851N will then

respond to the vol+ and vol- buttons on the remote control at any time.

It is also possible to adjust the volume using the rotary controller knob on the front

of the unit.

Whenever the 851N is showing its ‘Now playing’ screen turning the rotary controller

knob will adjust the volume. Pressing back or home etc. to access the menu system

allows the use of the rotary controller for menu browsing. If you are in a menu and

need to adjust the volume immediately simply press the ‘i’ button to go straight to

‘Now playing’ and then use the rotary controller.

The last used volume setting is memorised when the unit powered off.

USB audio class

USB Class options enable 851N compatibility with both USB Audio 1.0 and USB

Audio 2.0 interface formats. The default setting is USB Audio 1.0 which will work

driverlessly with most operating systems for 16-24 bit content at 32-96kHz. Note

USB Audio 2.0 requires a driver to be loaded for Windows. Without this selecting

USB Audio 2.0 will normally give no output. See earlier section on USB Audio for

advanced users.

System remote control

There are four options:

Standard 8-Series – is the default and works with the 851N remote control when

the handset is in default mode.

Alternate 8-Series – gives a secondary code set in cases where the 851N remote

codes are found to clash with another remote handset.

If Alternate 8-Series is selected on the 851N then the remote handset must also be

set to Alternate remote codes as well as follows:

Press and hold down the DAC/SM power button whilst inserting the batteries to

switch to Alternate 8-Series control codes.

By inserting the batteries without the DAC/SM power button held down will default

to Standard 8-Series codes.

CX-Series – choose this option to enable the system remote control from the CX

range to control the 851N.

No remote control – this will disable the ability of any of the above remote controls

to operate the 851N.

Stream Magic remote

Stream Magic remote is a free iPhone/iPod Touch/iPad application that allows

wireless control of the 851N or other Stream Magic powered Cambridge Audio

products.

The application allows full control of the 851N including Stream Magic Radio,

Streaming Services, UPnP Media, Presets, Queuing and more.

It also supports display of Album artwork and Station logos (where available).

To use Stream Magic Remote you will need a Wi-Fi network or Access point for the

application to connect to , the connection from your router to the 851N can then

be either Wi-Fi or Ethernet.

Search for Stream Magic Remote on the Apple App Store or browse www.stream-

magic.com for further details on this and other apps and features as they become

available.

The 851N allows the user to control playback volume via the Stream Magic mobile

application by either:

• Using the digital pre-amp inside the 851N, or

• Using a Cambridge Audio Azur amplier or AV Receiver connected to the 851N

via the Control Bus.

Digital pre-amp

When the digital pre-amp mode is enabled on the 851N, the mobile application

allows direct manipulation of playback volume via a slider located on the Now

Playing screen.

Connected Azur amplier/AV receiver

Users can enable Azur Mode in the Settings screen on the application when using

the 851N in conjunction with a Cambridge Audio Azur amplier/AV Receiver. Users

should then select whether they are using a Cambridge Audio Azur amplier or

an AV Receiver. If the 851N and the Amp/AV Receiver are connected using the

supplied orange Conrol Bus cable as shown below.

Volume control is now possible via the 'Now Playing' screen volume-up and volume

down buttons.

Instant on

Instant On, when enabled, allows 851N to enter a lower power suspended sleep

state using the Standby/On button.

To activate Instant On, go to "Settings -> Power-> Instant On" and set to "On".

In this mode, the 851N will consume slightly more power than Standby. However,

networking functionality remains alive in the background. This means

that 851N can be almost instantly woken up using not only the front panel, the

infra-red remote and the control bus, but also the Stream Magic App running on

iOS or Android devices.

This is not possible when the unit is in full Standby mode, regardless of whether

Instant On is enabled or not.

A short press of the Standby/On button will toggle the 851N between On and the

low power sleep mode.

Note: After putting the unit into sleep mode, you will not be able to wake the 851N

until 5 seconds have elapsed.

Full standby can still be activated by keeping the Standby/On button pressed for

more than two seconds. A subsequent press of Standby/On turns the unit fully on,

but remember that this can’t be done over the network (i.e. from the iOS app) and

that it takes longer to reach the full operational state.

Automatic power down

The 851N will switch itself off after 15 minutes if it is not playing anything and

there has been no user interaction with it during this time. As a default this is set

to 15 minutes, but you can increase or decrease this time, or turn this feature off

altogether if desired.

The Auto Power Down setting can be found in Settings > Power > Automatic Power-

down. There, using the rotary dial you can adjust APD from OFF to 1hr, in 5 minute

increments. Press the rotary dial to accept the new APD setting.

Edit digital input names

This allows you to customise the names associated with each digital input so that

they correspond to the actual device names connected to them.

There are six digital inputs:

• USB Audio

• D1 – D5

Each input is named as default by its input type. To rename an input, go to "Settings

-> Edit Digital Input Names", highlight the desired input and select it to rename.

The screen changes to a list of letters, with the current name displayed at the top.

To delete existing letters press the "Stop/Delete" button at the bottom left of the

display. Navigate through the letters and select each letter in turn to rename the

input. When nished, select the "Return" symbol at the end of the letter list (you

can press the "Home" button on the right hand side of the display to jump to it).

The name is then saved and the display returns to the Edit Digital Input Names

menu screen.

Factory reset

Puts all the settings back to their defaults as they were when they left the factory.

The 851N will ask you if you are sure you want to proceed before performing a

reset.

Note: If you perform a factory reset, you will lose any saved WEP/WPA keys for your

wireless network connection.

If you experience any trouble with your 851N, then you may nd it useful to visit the

help section on our webpage at: http://support.cambridgeaudio.com/.

If you have trouble with the Stream Magic service then you may also nd it useful

to visit the help section at www.stream-magic.com.

General Help guidelines:

If you have trouble connecting the 851N to your network, these steps may help to

resolve the problem:

• Conrm that a connected computer can access the Internet (i.e. can browse the

web) using the same network.

• Check that a DHCP server is available, or that you have congured a static IP

address on the 851N. You can congure a static IP address on the 851N using

the menu item ‘Settings -> Network Cong -> Edit Cong’, and then select ‘No’ for

‘Auto (DHCP)’. DHCP is however the recommended method.

• Check that your network’s rewall is not blocking any outgoing ports. As a

minimum, the radio needs access to UDP and TCP ports 80, 554, 1755, 5000,

6000 and 7070.

• Check your access point does not restrict connections to a particular MAC

addresses. You can view the radio’s MAC address using the menu item ‘Settings

-> Network Cong -> View Cong -> MAC address’.

• If you have an encrypted Wi-Fi network, check that you have entered the correct

key or passphrase into the 851N. Remember that text-format keys are case

sensitive. If, when attempting to connect to an encrypted network, your 851N

displays: ‘Wireless error’ followed by a 5-digit number, then please ensure that

you enter the correct passphrase for the network. If the problem persists, then

you may need to consult your network conguration.

If your 851N can connect to the network successfully, but is unable to play

particular Stream Magic stations, it may be due to one of the following causes:

• The station is not broadcasting at this time of the day (remember it may be

located in a different time zone).

• The station has reached the maximum allowed number of simultaneous listeners.

• The station is not broadcasting anymore.

• The link in our database is simply out of date.

• The Internet connection between the server (often located in a different country)

and you is slow.

• Try using a computer to play back the stream via the broadcaster’s web site.

If you can play back the station with a computer, you can use the form at

www.stream-magic.com to notify us so that we can investigate.

If you have problems with UPnP playback always check the following:

• Ensure your chosen UPnP server software is capable of serving the le type you

are trying to access. Some servers do not serve FLAC for instance.

• The 851N can only play non DRM les. Files that have DRM controls cannot

be played by the 851N. Some servers may be able to authorise and de-crypt

Microsoft Playsforsure before then serving the content to the 851N but this

operation is not guaranteed as it is purely a function of the server.

• If attempting to play 24-bit WAV or FLAC content note a wired Ethernet connection

is normally required for reliable operation due to bandwidth considerations.

• Check the 851N is capable of playing back the le type you are trying to access.

WMA, AAC, MP3, Vorbis, FLAC and WAV can currently be played. The 851N does

not support ALAC, WMA Pro, WMA lossless, RAW, AU or other le types not

mentioned.

If you have problems with USB Media playback always check the following:

• Check the 851N is capable of playing back the le type you are trying to access.

WMA, AAC, MP3, Vorbis, FLAC and WAV can currently be played.

• The 851N does not support ALAC, WMA Pro, WMA lossless, RAW, AU or other le

types not mentioned.

• For USB Media the 851N can only play non DRM les. Files that have DRM

controls cannot be played.

• Check that your device does not require more than 1A if it is powered from the

USB socket itself.

• Check your device is formatted in FAT32/NTFS format.

• The way you organise your USB media affects the size of internal database the

851N needs to build dynamically as you browse content. Good practice is to

create folders for Artists within which you should have a sub folders for each

Album which then containing the tracks for that Album. Libraries with thousands

of tracks in one folder will progressively slow down the 851Ns media browsing.

For all servicing, in or out of warranty, please contact your dealer.
