Digital Audio Server (DAS) Overview
The DAS is a true reference designed for the discerning Audiophile. The DAS has an extremely low noise
floor with greater spacial refinement, dynamic accuracy and fine detail retrieval than any other audio server
on the market.
The DAS has an integrated pre-amp and is capable of driving a power amplifier directly, thus replacing up to
4 separate units (e.g. CD transport, DAC, pre-amp, SUs) and interconnects.
The CAAS DAS has been designed to produce the highest audio quality possible. Within the pre-amp
section, this has been achieved through capturing the ideal qualities of a passive pre-amplifier without the
source loading and load driving capability issues normally associated with a passive pre-amplifier. Within the
Digital Audio Server section, this has been achieved through our bespoke 176.4k samples per second up-
converting parallel DACs and ultra low jitter clock, allowing near perfect data re-clocking and bit perfect I2S
digital signal transfer.
The DAS internal pre-amp consists of a bespoke switched resistor volume control. The front panel volume
knob simply provides a reference voltage to the internal analogue to digital converter (ADC) which in turn
controls a bank of high quality silver contact relays that switch different configurations of high quality metal
film resistors to produce attenuation levels between -50dB and 0dB in 128 discrete steps. Although this is a
more complex system than the standard audio potentiometer, the sonic purity far exceeds any audiophile
potentiometer on the market, irrespective of price and is therefore essential in producing the best sound
reproduction possible.
The bespoke volume control feeds a single JFET gain stage incarnation of CAAS Audio's proprietary “CSD”
amplifier. In the DAS this stage is configured as a DC coupled, zero feedback current buffer offering
extremely low THD, IMD and TIM and the cable and power amplifier drive capabilities that passive pre-
amplifiers lack, thus offering the most open, natural and transparent sound possible.
The DAS is an extremely versatile audio server and pre-amplifier with two analogue audio inputs, a single
S/ DIF input and a USB input. The DAS also has networking capability.
The DAS is fitted with a Raspberry I micro computer and a bespoke ultra low jitter re-clocking system that
up-samples digital data to 176.4k samples per second and feeds a parallel arrangement of 16 bit R-2R
DACs. The DAS is fitted with eight dedicated discrete regulated power supplies for both Left and Right
analogue channels and seven separate regulated supplies for the digital sections.
The DAS is primarily an Audio Server and the best performance will be achieved when files are accessed
from a USB pen or HDD. Alternatively digital audio can be streamed from either a NAS, a C, a tablet or a
smart phone over the LAN connection. A CD transport or other devices can be connected to the DAS
S/ DIF input, however this input bypasses our bespoke low jitter re-clocking system and therefore is not the
primary input.
All music files and data can be accessed through the on screen interface once the DAS has been connected
to a TV or monitor (though HDMI). If the TV has HDMI CEC then all the DAS functions can be accessed
through the TV remote, alternatively the functionality can be accessed through a LAN interface, tablet or
smart phone.
The power supply is a key component in achieving the maximum performance from the audio sections and
for this reason the DAS is fitted with a high specification mains filter and two separate transformers, one for
the analogue sections and one for the digital sections.
The DAS has analogue DC coupling from input to output and a short signal path.

Important Precautions (Must ollow)
Water and moisture
The DAS should not be used near water. Care should be taken not to allow the DAS to fall into water or
liquids and ensure liquid is never spilled onto or into the DAS.
Power sources
The DAS voltage and current rating is indicated on the units rear panel. This will state either 240Vac or
120Vac. Two T1A time-lag fuses are included for 120V versions and two T0.5A fuses are included for the
240V versions. The input frequency rating of the power supply is 50Hz to 60Hz. The DAS typically draws
less than 20W during the normal operation. lease verify that the indicated voltage requirement is consistent
with the mains voltage in your location.
Grounding
We provide a standard IEC AC main cable that fits into the rear of the DAS. The DAS is equipped with an
earth ground provided by this cable and connection. DO NOT defeat this ground.
Power and Signal cables
The DAS is supplied with a power cable that meet UK legislated requirements. As with all audiophile
equipment the power cable should be the last item attached and the first item removed whenever equipment
is added or removed from the audio chain. Any cables (power or signal) should never be connected or
removed while the equipment or supporting equipment is powered up. Failure to pay attention to this
precaution may result in damaged equipment.
Ventilation
Audio equipment may run hot. The installation must allow for this heat dissipation. We recommend free air
circulation around the product. This can best be achieved by leaving at least a 20cm gap around the unit.
The DAS should not be installed or situated near any other source of heat (e.g. central heating radiator or on
top of an amplifier).
Servicing
To reduce the risk of fire, electrical shock or other injuries, the user should not attempt to service the DAS.
lease do not open the DAS. There are no user serviceable parts inside the DAS. Opening the DAS will
invalidate any warranty offered. Servicing must be referred to qualified service personnel only.
Burn in period
When you first power up the DAS, you may not experience the maximum performance of this audio server,
the DAS can require a burn in period of up to 100 hours. Additionally the performance of the DAS can vary
slightly over its warm up period.

Using the Digital Audio Server (DAS)
The Digital Audio Server is primarily an audio server. The audio server has an S/ DIF input at the rear that
can be selected by the “DI” selection on the front panel. This allows third party digital sources to be
connected to the audio server, such as CD transports. It should be noted that by far the best audio quality
playback will be achieved through using the audio server as it is intended, that is as a dedicated audio server
(the “AS” input selection on the front panel) and not through third party connected devices. Additionally the
S/ DIF input bypasses CAAS Audio's low jitter re-clocking system, so this advantage can not be utilised with
this input.
Adding Music Files to your US Storage
We recommend you use EAC (exact audio copy). Download and install EAC onto your C / Laptop and RI
your CDs using EAC (We recommend WAV or FLAC format). Then simply plug your USB storage into your
C / Laptop and copy the music files across. Once finished, remove the USB device and plug it in to the
USB socket on the rear of the DAS. The DAS should then auto detect the drive and you're ready to go. See
the next section for accessing these music files.
Note: Use either 3.5inch externally powered HDD or USB storage pen, DO NOT USE 2.5 INCH USB
POWERED HDD this will not work!
Setting up the DAS and Accessing Music Files
1. Make sure the Audio Server is turned OFF.
2. Insert Storage device in one of the rear USB ports (use either 3.5inch externally powered HDD or
USB storage pen, DO NOT USE 2.5 INCH USB OWERED HDD this will not work!).
3. Do not insert or remove USB devices while the Audio Server is turned ON, this will force a re-boot.
Only insert and remove USB devices while the Audio Server is turned off!
4. Connect a CEC enabled TV to the HDMI connection on the rear of the Audio Server (while the Audio
Server is turned off). See the following section for TV CEC control.
5. Once the unit has been turned on, access the Audio Server through the TV remote control and CEC
function.
◦The audio server can also be accessed through a web server, tablet or smart phone, the unit will
need to be connected to a network (through the rear LAN port) and the appropriate XBMC
remote control software will need installing on your smart phone / tablet.
6. Make sure the “AS” LED has been selected on the front panel.
7. The Audio Server will take approximately 30 seconds to boot. Once booted the XBMC menu screen
will be displayed.
8. Scroll sideways and select Music, then scroll down and sideways to select either “Artists”, “Albums”
or “Files” under the music menu. Navigate using either the TV remote, smart phone or tablet (see
screen shots below).
9. If you select either “Artists” or “Albums” this should take you straight to a list of artists or albums, you
can just select the track you wish to play from here. If you select “Files” you will get a choice of
media drives / storage devices. Next select the storage device. This will then give you a list of artists
and albums, select the track you wish to play from here (see screen shots below).

Controlling the Digital Audio Server (DAS)
TV CEC Control
If your TV is CEC enabled you can control the audio server using the TV remote:
1. Connect a CEC enabled HDMI cable between the TV and the HDMI port on the rear of the audio
server.
2. Note: On some TVs only HDMI port 1 is CEC enabled.
3. If the audio server does not recognise the CEC connection, turn both the TV and audio server off
and then back on again whilst the HDMI cable is connected.
4. Once CEC has been recognised, you can scroll through the music files stored on the USB media.
lay track, pause, stop etc..
Network Control
You can control the audio server from other devices connected to your network, such as a smart phone or
tablet. To do this you must first install XBMC remote (or other) on your smart device. The procedure to do
this is highlighted below in the “Installing & Setting up XBMC & Yatse Remote Apps” section.
Web Interface
The web interface can be accessed on port 80 by opening a web browser and typing the DAS I address
followed by :80 ( e.g. ://192.168.1.14:80 ) into the URL bar.
Alternatively you may be able to type the host name followed by :80 ( i.e. http://caasaudio:80 ). Note: this
may not work with a lot of routers and you may need to type the DAS I address and :80 into the URL bar.
Notes:
•The DAS IP address will pop up in the right hand bottom corner of the TV on DAS boot up. lease
make a note of this I address (the DAS must be networked first for this to happen).
•The DAS IP address can also be found through other techniques, such as downloading the App
“Fing” to your smart phone / tablet. You can then run Fing and it will display the I addresses of all
devices connected to your network. Alternatively if CEC is enabled on your TV, you can use the TV
remote to scroll to System → System info where the I address will be displayed.
Recommended DAS Shut down / Turn off procedure
The DAS should always be shut down in a controlled manner just as you would a C or laptop. The Audio
Server should always be shut down via the power icon in the lower left corner of the screen:
1. Select the power icon in the bottom left corner of the screen (using either a CEC enabled TV remote,
smart phone, tablet or web interface).
2. Then toggle down and select “ ower off system”.
3. The DAS will then power down and you can then turn the unit off at the rear.
Page 9

DLNA / UPnP Audio Interface, Networking & ile Sharing
The DAS can connect to a home network and play audio files stored on DLNA / U n enabled devices.
The DAS can be connected to a TC /I network via a wired connection. Network connection enables the
DAS to play audio files stored on DLNA / U n servers, computers and network drives. The DAS has a
standard Ethernet socket fitted on the rear panel. For wired network connection this socket should be
connected to a spare Ethernet socket on your network router.
Networking the Digital Audio Server (DAS)
1. Connect a CAT5 LAN cable to the LAN port on the rear of the audio server and the other end to a
free LAN port on your router.
2. The audio server should now be networked. The DAS is DHC aware by default, so if connected to
a DHC enabled router (most are), your router will assign an I address to the audio server.
3. You should be able to access the audio server through the assigned I address. If you download
“Fing” for your smart phone it will scan all your network attached devices and return their I address
etc.. this can be quite useful.
4. Alternatively you can view / adjust the I address and other setting in the “CAAS Audio
Configuration” window on your TV (see the section below “CAAS Audio Configuration set up”).
CAAS Audio Configuration Set Up
The audio server network settings can be configured under " rograms → CAAS Audio Configuration"; this
procedure is outlined below:
1. Switch the audio server ON, once the audio server has booted.
2. On the TV, scroll right to the " ROGRAMS" menu item, click on it, this should give you a list of
programs.
3. Scroll down to "CAAS Audio Configuration" and click on it, this should load the configuration window.
4. The configuration window has two parts (tabs) to it, "Network Configuration" and "Software Updates"
5. You can move up and down along the options and the tabs at the top left and right.
6. On the Network Configuration page, you can configure either:
◦Ethernet (Hard Wired) or Wireless (WiFi).
◦Whether the I address is fixed or comes from DHC (Dynamic Host Configuration rotocol).
◦If you are not using DHC , I address, subnet masks and gateway addressed can all be
configured.
7. On the Software update page, you can select: "Check for software upgrade", once selected the DAS
will search for any software upgrade and feedback if they are available, it is recommended to follow
the on-screen advice during the upgrade process and it is recommended that you do NOT reboot or
power off the unit during an upgrade procedure.
Note: lease refer to your router manual for further details about configuring DHC and changing device I
addresses should you need to.
Page 10

Windows Network (SM ) file sharing
This is the preferred method of sharing files between the DAS and Windows network devices or NAS.
1. Connect the network cable between the DAS and your router.
2. Ensure that file sharing is enabled on your window device ( C / Laptop) or NAS (A guide to this is
given at the end of this document).
3. On the DAS; you will need to add the shared device as a media source. You do this in the following
way, select:
Music → iles → Add source→ Browse → (scroll down to) Windows network (SMB)
See screen shot below.
4. Then select your workgroup / shared folder and then select OK. You may then need to select OK on
the next screen as well.
You should now be able to access / view your shared files as you would a local device / drive from the main
menu (Select “Music” and your shared device should be there.
Note: You may be prompted for a user name and / or password. This will be your router / system password.
Page 11

UPnP Audio Interface
This option is only to be used to access other U n devices (e.g. file sharing between two XBMC devices).
The procedure is fundamentally the same as SMB sharing:
1. Firstly you need to enable U n on the source XBMC device (the files you wish to share / access):
Settings → Services → UPnP. The enable the UPnP server
See screen shot below.
2. For the XBMC client device (the DAS) you will add the source device as a media source:
Music → iles → Add source→ Browse → (scroll down to) UPnP Devices.
See screen shot below.
Select the source that you wish to share. You may wish to re-name the source.
You should now be able to see everything on this source.
Page 12

Streaming Music from a Phone / Tablet to the Audio Server
Note: This procedure differs slightly from device to device, so outlined here is a generic procedure that will
be similar to that required.
1. The audio server must be networked. Connect a LAN cable between the audio server LAN port and
your router.
2. Set up a connection between your smart device and the audio server. This can be done using a
procedure such as the below, however this does differ from device to device:
3. Make sure your smart device is connected to your home network via WiFi. If you are not sure how to
do this, information on how to do this can be found on the internet or in your smart device manual.
4. On your Smart device: You first need to install and set up “XBMC Remote”or “Yatse”. The
procedure to do this is directly below! (the next section).
5. Once XBMC Remote has been installed, you should be able to access your music files on your
smart device (e.g. On Android → All Apps → Music).
6. Once in “Music”, there should be an icon for selecting a player, possibly at the top of the screen.
Choose Select player.
7. Then under WiFi player you should see something like XBMC or CAAS Audio Server, select this and
hit “Done”.
8. Any music files you play on your smart device should now be sent to the DAS.
9. Note this procedure does differ from device to device and for iOS systems but the information you'll
need is readily available on the internet.

Updating the X MC music Library and Thumbnails
The music library information can be updated / downloaded from online servers. Note: The audio server must
be networked / have a connection to the internet for this feature to work.
This feature should allow more information to be displayed on the TV screen, including cover art and
thumbnails. This is most easily done via a smart phone, once XBMC remote has been installed on the smart
device. The procedure to do this is as follows:
1. Select XBMC remote control (on the smart device).
2. On the TV, navigate until you are at the root folder window, containing all the music (e.g. USB1).
