either the mains cable supplied or a Naim Power-Line.
2.3 FM/DAB Aerial Connection
The optional NAC-N 172 XS FM/DAB module will only be
able to provide high quality FM and DAB radio if a strong,
interference-free radio signal is available. The
NAC-N 172 XS rear panel FM/DAB Aerial socket must
be connected, via 75 Ohm low-loss coaxial cable, to a
suitable aerial. The aerial should be mounted clear of large
obstructions and as high as possible; ideally on a roof.
Note: Your local retailer should be able to offer advice on
a suitable aerial and aerial installer.
2.4 Audio Inputs and Outputs
2.4.1 Audio Signal Inputs
The NAC-N 172 XS provides three stereo analogue inputs
and five S/PDIF digital inputs including one combined
analogue/digital input socket. Connection to the inputs is
made via a variety of socket types. The following table lists
the inputs and their socket type:
Input Type Socket
an. 1 Analogue 5-pin DIN
an. 2 Analogue RCA phonos
front panel Analogue 3.5mm jack
Digital 3.5mm mini-TosLink jack
dig. 1 Digital Coaxial (RCA phono)
dig. 2 Digital Optical (TosLink)
dig. 3 Digital Coaxial (RCA phono)
dig. 4 Digital Optical (TosLink)
Note: The front panel analogue/digital jack socket can
accept both conventional analogue 3.5mm plugs and
mini-TosLink optical digital plugs. It will automatically
identify the type of plug inserted and handle the signal
appropriately.
Always use high quality interconnect cables to connect
sources to NAC-N 172 XS inputs.
2 NAC-N 172 XS Installation and Connection
Your NAC-N 172 XS should be installed on an equipment stand intended for the
purpose. Ensure it is well ventilated, and do not stand it directly on top of another item of
equipment. It should be installed in its final location before connecting cables or switching
on. The NAC-N 172 XS has no standby mode and is intended to be left switched on.
Connecting the NAC-N 172 XS to mains power and to a variety of audio peripherals and
sources is described in the following paragraphs. Diagram 2.1 illustrates the NAC-N 172 XS

NAC-N 172 XS Installation and Connection
2.4.2 Audio Signal Outputs
The NAC-N 172 XS provides preamplifier and line signal
outputs. Connections to the outputs are made via the
socket types listed below:
Output Type Socket
Preamplifier Analogue stereo 4-Pin DIN
2 x RCA phono
Line Analogue Stereo 2 x RCA phono
Note: The DIN and RCA preamplifier output sockets
operate in parallel and can be used simultaneously. If a
subwoofer is to be used it should be connected to the
second preamplifier output using a dedicated Naim
subwoofer connection cable. Contact your local Naim
retailer or distributor if necessary for more information on
subwoofer cables.
Note: The preamplifier outputs are taken after the NAC-N
172 XS volume and balance controls so peripheral
equipment connected to them will respond to NAC-N
172 XS volume and balance control changes. The output
always reflects the selected input signal.
Note: The line output is taken before the NAC-N 172 XS
volume and balance controls so the output signal will not
reflect NAC-N 172 XS volume and balance control or mute
function. The output always reflects the selected input
signal.
2.5 Headphone Output
The NAC-N 172 XS is fitted on its front panel with a 3.5mm
stereo headphone socket. Insertion of a headphone plug
will mute the preamplifier outputs.
Note: NAC-N 172 XS controls and stores volume settings
separately for headphone and preamplifier outputs.
2.6 Signal Ground Switch
The NAC-N 172 XS is fitted on its rear panel with a Signal
Ground switch offering two positions: Chassis or Floating.
Select the Chassis position unless the NAC-N 172 XS is
connected in a hi-fi system incorporating another earthed
source component, or mains “hum” is audible through the
loudspeakers. Contact your retailer, distributor or Naim for
advice if necessary.
Note: “Connected” in the context above means an
analogue audio signal cable that includes an earth
connection. The NAC-N 172 XS digital inputs are isolated
from the mains earth regardless of the Signal Ground switch.
Note: All Naim CD players are earthed so the Signal
Ground switch should be set to floating if one is connected
in the system.
No damage will be done if the wrong Signal Ground
position is chosen, however the system sound quality may
be compromised.
Note: The NAC-N 172 XS negative analogue input and
output connections for each channel are common.
The mains earth (ground) should always be connected
regardless of what other equipment is used. The mains
earth primarily grounds the case and the electrostatic
screen within the transformer, and is only connected to the
signal negative if the Signal Ground switch is set to Chassis.
In order to avoid hum loops, the signal negative of the
whole system should be connected to the mains earth in
one place only.
2.7 USB/iPod Interface
The NAC-N 172 XS is fitted with a front panel USB interface
intended for the connection of Apple iPod and iPhone
models and USB memory hardware carrying audio files. The
USB interface should not be used for any other purpose.
Depending on the setup options chosen, iPod and iPhone
batteries will be charged when connected to the USB
interface (see Section 4.3.5).
2.8 Network Connections
The NAC-N 172 XS can be connected to a TCP/
IP network via either a wired or wireless connection.
Network connection enables the NAC-N 172 XS to play
internet radio data streams or play audio files stored on
UPnP™ servers such as the Naim UnitiServe and HDX, and
appropriately configured computers and network drives.
2.8.1 Wired Network Connection
The NAC-N 172 XS is fitted on its rear panel with a standard
Ethernet socket. For wired network connection this socket
should be connected to a spare Ethernet socket on your
network router.
Note: Ethernet-over-mains hardware may be used and
provides a simple and convenient method of wired home
network connection. However, depending on mains wiring
factors specific to each home environment, the presence
of network data on the mains supply may compromise
overall system sound quality. If any sound quality
compromise is found to be unacceptable, dedicated
network cabling should be installed or wireless networking
should be employed.
2.8.2 Wireless Network Connection
If NAC-N 172 XS is to connect wirelessly to the home
network the supplied Wi-Fi antenna must be fitted to the
rear panel wireless antenna socket. Wireless configuration
will also be necessary before NAC-N 172 XS is able to
connect to your home network. See Section 4.6.1.
Note: An optional high-gain Wi-Fi antenna, the WA5,
is available. The WA5 may improve Wi-Fi connection
reliability in some installations. Contact your Naim retailer
for more information.

5
NAC-N 172 XS Installation and Connection
2.8.3 Network Settings
The NAC-N 172 XS is set up when originally shipped not to
require any on-site TCP/IP configuration but to connect
to a network automatically (it uses DHCP by default).
However, if your NAC-N 172 XS has been previously used,
its network configuration may have been altered leaving it
unable to connect automatically. If this appears to be the
case ensure that DHCP is selected in the Network Settings
menu (see Section 4.6 of this manual) and re-start the
NAC-N 172 XS. If problems still persist contact your retailer,
installer or Naim Audio directly.
Note: Before reporting network connection problems carry
out a Factory Reset operation. Select Reset All Settings
from the Factory Settings setup menu. See Section 4.11.
Note: A NAC-N 172 XS switched on without a working
wired network connection will only be able to connect
to a home network wirelessly. To use an Ethernet (wired)
connection, switch the NAC-N 172 XS off, connect the
network and switch it on again.
Note: For internet radio to operate, the NAC-N 172 XS
requires connection to a broadband internet service.
2.9 System Automation
The NAC-N 172 XS can be linked using System Automation
to control some Naim CD players. This enables a Naim CD
player to be controlled from the n-Stream iPhone and iPad
App.
To take advantage of System Automation, connect the
NAC-N 172 XS rear panel Remote Out socket to the CD
player Remote In socket. Use a cable terminated with a
3.5mm jack plug at one end and a 3.5mm jack or phono
plug as necessary at the other end.
Note: Stereo and mono 3.5mm jack to 3.5mm jack can
be used for System Automation. If a stereo 3.5mm jack to
phono plug cable is used, connect the left channel phono
plug.
Note: System Automation is switched off by default. A full
description of its configuration and use can be found in
Section 4.10.
2.10 External Control and Interface
The NAC-N 172 XS is fitted on its rear panel with a 3.5mm
jack Remote In socket and a mini-USB interface socket.
The Remote In socket can be used for RC5 remote control
of the NAC-N 172 XS via a wired connection or a remote IR
repeater.
The mini-USB socket enables firmware upgrades and
diagnostic tests to be carried out. Contact your Naim
retailer for more information if required.
Note: The mini-USB interface is not intended for the
connection of USB memory devices.

also provided. Use the handset up (5) or down (6) keys
to scroll through the list and the ok/list key to select a
network.
Note: The NAC-N 172 XS is compatible with most commonly
used Wi-Fi standards. Routers that support 802.11b and
802.11g will work, however those with 802.11n compatibility
are recommended for best results.
Note: As with any wireless network hardware,
NAC-N 172 XS connection reliability will be affected by
both network router performance and Wi-Fi signal quality.
To minimise the possibility of poor connection reliability,
NAC-N 172 XS should be connected to network audio
sources by no more than one wireless “leg”. Other “legs”
necessary between NAC-N 172 XS and the network audio
sources should be wired.
Note: The NAC-N 172 XS cannot connect to a “hidden”
wireless network.
If the selected network is secure
and requires a passphrase or
access key to join, the
NAC-N 172 XS will display an alert
message. Pressing the handset
ok/list key will then open a text
entry screen for entry of the
passphrase or access key.
Use the handset numeric/text
keys to enter the passphrase or
access key taking care to ensure
that the letter case is correct.
Press the handset ok/list key
when text entry is complete. In
the illustration the passphrase is
“flatfish”.
If the network is successfully
joined the NAC-N 172 XS will
display a confirmation screen.
If an incorrect passphrase or
access key is entered the
NAC-N 172 XS will display an alert
message.
Note: As a security measure, a router may also require
the NAC-N 172 XS’s MAC address to be entered before
allowing it to join the wireless network. This type of security
feature is known as ‘MAC address filtering’. The NAC-N 172
XS MAC address is shown in the ‘Factory settings > System
Status’ page.
Note: The wireless passphrase/access key is created when
the wireless router is first set up and could be a word or a
series of numbers and letters. If the passphrase/access key
is not known, check on the router settings page or with the
person who initially set up the router.

4.6 The Network Settings Menu
The Network Settings menu
enables NAC-N 172 XS network
parameters to be customised
to suit the router and network.
The options are tabulated and
described in the following sections:
Parameter Options
Name: User definable (text entry)
Default: 172XS-xxxx
Wireless: Not Used / Wireless Network Names
Status: Connected / No Signal / Login Failure /
Busy / Etc.
DHCP: Yes / No
The Name parameter enables the NAC-N 172 XS’s default
network name to be changed.
The Wireless parameter enables a wireless network to be
chosen and joined. See Section 4.6.1 below for detailed
wireless set up notes.
Network Status displays the current network connection
status.
The DHCP parameter enables the NAC-N 172 XS network
settings to be modified. In most cases, specifying Yes
and leaving the NAC-N 172 XS set to DHCP, will be the
appropriate option. See Section 4.6.2 below for notes on
non-DHCP network connection.
Note: Devices installed on a network have an IP address
through which they are identified by all the other items
on the network. DHCP is a set of rules that enable the
automatic allocation of addresses as items are connected
(or switched on while connected) to the network. The
NAC-N 172 XS is set up by default to use DHCP.
Note: If the NAC-N 172 XS is connected to the network
both wirelessly and via Ethernet (wired), the Ethernet
connection will take priority.

The mute function silences the NAC-N 172 XS headphone,
preamplifier and line outputs. Mute is engaged or
disengaged by touching the front panel logo or pressing
the handset mute key. Mute is indicated by the display
volume icon flashing.
Note: Logo-touch muting can be disabled. See Section 4.7
5.3 Preamplifier Display
In normal operation the NAC-N 172 XS front panel display
primarily shows information relating to the selected input.
It will change temporarily to show adjustments such as
volume level and signal mute state as these are made.
5.4 Signal Outputs
The NAC-N 172 XS provides a preamplifier output, a line
output and a headphone output.
The preamplifier output is designed to be connected to a
downstream power amplifier. The line output is designed
to enable a variety of downstream ancillaries to be
connected. These might include a second headphone
amplifier or a remote integrated amplifier.
The NAC-N 172 XS headphone amplifier is able to drive
most commonly available headphones. Insertion of a
headphone plug will mute the NAC-N 172 XS preamplifier
outputs.

will automatically download a
list of available internet radio
stations. When the iRadio input
is subsequently selected, a list
mode menu will be displayed that shows all the available
stations sorted by location, genre, podcast location,
podcast genre, new station and most popular stations. The
display will automatically enter list mode so the handset
up (5), down (6), left (3) and ok/list keys can be used
to browse the menus and select stations. In long lists the
handset numeric/text keys can be used to search the list
alphabetically.
Once a station is selected the NAC-N 172 XS display will
exit from list mode and revert to normal mode. To re-enter
list mode for further list browsing and selecting press the
handset ok/list key.
Pressing the handset info ( ) key while a station is
playing will sequentially display the station (stream) name,
elapsed time, stream info, buffer level and any station info
broadcast.
Note: Buffer level indicates the quantity of stored data
within the NAC-N 172 XS and reflects the ability of the
network to provide data at the necessary rate.
It is possible for an internet radio
station listed to be “off-line” and
be unavailable when selected. If
this occurs an alert message will
be displayed.
Note: If the NAC-N 172 XS is left
muted for more than five minutes while an internet radio
station is selected the data stream will be stopped in order
to save network bandwidth. The stream will re-start as soon
as mute is disengaged.

The NAC-N 172 XS incorporates a radio module able to play internet radio streams
and optionally to receive FM and DAB transmission. FM and DAB operation requires an
appropriate aerial to be connected to the rear panel aerial input. Internet radio requires
the NAC-N 172 XS to be connected to a broadband internet service via a network router
that incorporates an appropriate firewall. The NAC-N 172 XS is able to store a total of forty
station presets (favourites) across all three tuner modes. Select the FM, DAB or iRadio input
