When setting up
To ensure that your Red Reference works efficiently and safely, please pay particular
attention to the following issues.
ventilation
Your Red Reference should have at least 5cm of clear space all around it to ensure a free
flow of air at all times. We do not recommend that you place Red Reference directly on a
carpet.
AC lead and plug
All Chord equipment comes supplied with the correct power lead and plug. This should be
used at all times.
if you need to fit a plug for UK/Europe
Connect the blue wire to the neutral terminal
Connect the brown wire to the live terminal
Connect the yellow/green wire to the earth terminal
if you need to fit a plug for US/Canada
Connect the white wire to the neutral terminal
Connect the black wire to the live terminal
Connect the green to the earth terminal
earthing issues in Europe
In some European countries a hum may occur if your Red Reference is connected to mains
sockets that do not have an earth. If this is the case please ensure that:
1. Your transport is connected via a multi-way mains block, which contains an earth point
at each socket outlet. This is to ensure that the chassis metalwork of each item is
connected together.
2. We recommend that an earthing method for your building be implemented.
3. Use the connecting points on your Chord unit and connect to an available earth point.
!4
Safety Warnings
It is important that your Red Reference is earthed at all times via its own mains lead. Failure
to do this may be hazardous. The power supply components within the transport are
designed to operate at lethal voltages and energy levels. Circuit designs that embody these
components conform to applicable safety requirements. Precautions must be taken to prevent
accidental contact with power-line potentials. Do not connect grounded test equipment.
Caution: This product employs a laser that emits both visible and invisible radiation.
Removal of the top cover or tampering with any of the enclosed electronics may result in
exposure to hazardous levels of laser radiation that could cause eye damage. To prevent
injury this product should be returned for qualified service to Chord Electronics Ltd.
There are no user serviceable parts within the Red Reference CD player.
Unauthorised tampering or dismantling of this product will invalidate the
warranty and could cause injury.

Red Reference - rear panel connections
All the input and output connections of Red Reference are situated on the rear panel of the
transport.
Red Reference has three types of digital output; Optical, Coaxial and AES/EBU, three types
of digital input optical, USB HD and AES/EBU and both balanced and unbalanced analogue
outputs.
In addition to the standard digital outputs, a special Dual Data output provides an upsampled
digital output at 176.4KHz. Connection to both AES/EBU is required for this mode. Please
note:- When using Dual Data mode with two cables please set the operating frequency to
176KHz via the front panel.
!7
Coaxial digital output
SPDIF OUTPUT
Red Reference - coaxial connection
Red Reference has one SPDIF output as shown above. This outputs digital audio data from
any CD playing.
All coaxial connections use BNC connectors with 75ohm impedance.
Although less
common than RCA-phono digital connectors, BNC connectors exhibit consistent impedance
behaviour and are essential for the correct transfer of digital audio data.
If your digital-analog converter only has RCA-phono coaxial digital inputs, it is worth
having a cable made by a specialist manufacturer. Please avoid RCA-BNC adaptors as they
will undoubtedly impair the sound quality. In all cases a correctly screened cable should be
used.
Frequency Settings
The output frequency can be set via the front panel to 44KHz or 88KHz. If you select the
176K option the output will remain at 88KHz.

AES/EBU digital outputs
AES/EBU
OUTPUT 1
AES/EBU OUTPUT 2
For installations that require a long run of cable between the transport and digital-analog
converter we would recommend using a balanced AES/EBU connection. The AES/EBU will
output digital audio data from any CD playing and can either be used as two identical
outputs or combined as one 176.4KHz dual data output.
Frequency settings
When the front panel frequency switch is set to 176K, the AES/EBU outputs send the Dual
Data output as outlined in the previous section.
This may be useful when using Red
Reference with certain high-resolution D-A converters.
When the frequency switch is in the 88K position, each AES/EBU output sends data at
88.2kHz; when in the 44K each output sends at 44.1kHz.

Optical digital output
OPTICAL
OUTPUT
The optical digital output uses a standard TOSlink connection and can be used with DAC64
and several other digital to analogue converters. This outputs digital audio data from any CD
playing.
In particular an optical connection can be very useful in the prevention of earth loops, as
there is no electrical connection between two products in a system. This may be required
when combining Red Reference with products from other manufacturers.

Wordclock input
WORDCLOCK
INPUT
A dedicated wordclock input may be required in professional recording and broadcast
applications, generally wordclock outputs are not found in domestic audio products.
As Red Reference is a reference-grade CD player, it is very likely that our Professional
Audio customers will use it as a CD source and so may need to synchronise it within a larger
digital system.
The wordclock input operates at 44KHz only and automatically switches when a signal is
connected.
Digital inputs
The Red Reference comes equipped with three different types of digital inputs, allowing
compatibility with virtually any digital audio source equipment. Digital audio source
equipment includes CD transports, DVD players and Mini Disc players and now USB
computer connection. The digital inputs consist of one AES balanced XLR input (XLR), one
Plastic Fibre Optical TOSLink input (OPT) and one 24 bit, 192KHz USB input (USB).
These inputs can be selected via the I/P button on the front panel and will output analogue
audio from both the balanced and unbalanced connections.

configuring the computer to use Red Reference USB input
configuring a PC with Windows XP
A PC with Windows XP can use Red Reference in two different ways: Direct Sound (DS)
and
Kernel Streaming (KS). Direct Sound is suitable for players which can’t operate in Kernel
Streaming mode (such as Windows Media Player and iTunes) or for Internet streaming.
Kernel Sound can be chosen (for better performance) with players which can operate in
Kernel Streaming mode (such as FooBar, Winamp, Monkey Media, JRiver).
Please note that in Windows XP there is no direct sample rate setup in the audio
settings panel. Sample rate can only be selected in Kernel Streaming mode with an
appropriate player.
configuring for Direct Sound with Windows XP
Connect Red Reference to your PC. Then, go to the Control Panel and launch the Sound and
Audio Peripherals utility. Select the Audio tab. In the Predefined Peripheral drop-down menu
of the Playback area, select “Chord Async USB 44.1kHz–192kHz”
Then, select the “Voice” Tab. Again, select “Chord Async USB 44.1kHz–192kHz” in the
drop-down menu of the Playback area. Click on OK button. Please be advised that even if
the Red Reference peripheral is listed as “kernel streaming”, it will operate in Direct Sound
mode when listed here.
From now on, unless Red Reference is disconnected or settings are changed again, Red
Reference is the audio peripheral all audio programs will use when operating in direct sound
mode.
configuring for Kernel Streaming with Windows XP
Kernel Streaming has no standard setting in Windows XP. KS must be selected in the
specific player you choose to use.
For example, when using FooBar, with Red Reference connected to the PC, go to the File/
Preferences/Playback /Output tab and select “Chord Async USB 44.1kHz–192kHz” as
output device.
Other players will require different settings.
using Red Reference in both Kernel Streaming and Direct Sound mode
When Red Reference is selected as an audio peripheral, it’s possible to use it in both Kernel
Streaming mode and Direct Sound mode. When using it in KS mode, it is necessary that no
other application accesses Red Reference in DS mode. If this happens, Windows XP’s
Kernel Mixer takes control of Red Reference’s driver and from then on, no KS application
can access the Red Reference unless the PC is restarted or Red Reference connection to the
PC is cycled.
configuring a PC with Windows Vista or Windows 7
A PC with Windows Vista or Windows 7 can use Red Reference in three different ways:
!13
Direct Sound (DS), Kernel Streaming (KS) and WASAPI.
DS is suitable for players which can’t operate in Kernel Streaming mode or with WASAPI or
for Internet streaming;
KS can be chosen (for better performance) with players which can operate in Kernel
Streaming mode (such as FooBar, Winamp, Monkey Media, JRiver). WASAPI (Windows
Audio Standard API) is a standard interface for audio players which gives you the same
performance of KS with applications which can’t operate in KS mode, at the cost of higher
CPU load.
configuring for Direct Sound with Windows Vista or Windows 7
Open control Panel and select Hardware and Sounds. Under Audio, click on Manage Audio
Devices. Set Chord Async USB 44.1kHz–192kHz as default device. Then, click on OK.
configuring for Kernel Streaming with Windows Vista or Windows 7
As for Windows XP, Kernel Streaming has no standard setting in Windows Vista and
Windows 7. KS must be selected in the specific player you choose to use.
For example, when using FooBar, with Red Reference connected to the PC, go to the File/
Preferences/Playback /Output tab and select “Kernal Streaming Chord Async USB 44.1kHz–
192kHz” as output device.
Other players will require different settings.
configuring for WASAPI with Windows Vista or Windows 7
Similar to Kernel Streaming, WASAPI cannot be directly accessed. WASAPI must be
selected in the specific player you choose to use.
For example, when using FooBar, with Red Reference connected to the PC, go to the
File/Preferences/Playback /Output tab and select “WASAPI: Chord Async USB 44.1kHz–
192kHz” as output device.
Other players will require different settings.
configuring Mac OS X
Open the System Environment Settings from the Start menu. Open the Sound options from
the System Environment settings.
Select the Output tab and confirm the Chord Async USB 44.1kHz–192kHz USB audio
codec appearance as the default output device.
sample Rate Setup
Open the Audio MIDI Settings options (Application – Utility - Set Audio MIDI).
Select the Audio Output tab in the Set Audio MIDI.
Select the desired sample frequency from the options given.
configuring the player for Kernel Streaming: some examples
FooBar
To use FooBar in KS mode it is necessary to download the DLL for Kernel Streaming from
the FooBar2000 website and install it in the Components sub-folder inside FooBar2000
main folder in your hard disk. The DLL can be found at http://www.foobar2000.org/
components/view/foo_out_ks. It is a zip
folder which contains the DLL.
Extract it from the zip and copy to the Components folder.
Then, restart FooBar, go to the File/Preferences/Playback/Output window and set
parameters.
5.2. Winamp and MediaMonkey
These two players are actually the same player with different skins, so they can share the
same plug-ins. A freeware plug-in for Kernel Streaming by Steve Monks is available on the
Internet (http://www.stevemonks.com/ksplugin/) that can be used to enable Kernel
Streaming operation with these players.
Download the zip file, extract the dll file and copy it into the Plugins folder inside Winamp
main folder. With Red Reference connected, right-click on Winamp and select Display/
Select Plug-ins. The Preferences window of Winamp will open. Go to Plug-in/Output and
select “Kernel Streaming Output”. Then click on Configure button. Choose Red Reference
Kernel Streaming in the output device list.
configuring the player for WASAPI: an example
FooBar
To use FooBar with WASAPI under Windows 7 it is necessary to download the DLL for
WASAPI from the FooBar2000 website and install it in the Components sub-folder inside
FooBar2000 main folder on your hard disk.
The DLL can be found at http://www.foobar2000.org/components/view/foo_out_wasapi . It
is a
!14
zip folder which contains the DLL. Extract it from the zip and copy to the Components
folder.
Then, restart FooBar, go to the File/Preferences/Playback/Output window and set
parameters.
Sample rate setup for Red Reference (Windows Vista Example)
Once the driver software has been installed and the Red Reference connected to a Windows
based computer then the digital audio sample rate needs to be set as follows:Stage 1:- Configuring audio devices
Connect the Red Reference to the computer with the supplied USB cable.
Run the Windows Control panel and select Hardware and Sound

!17
direct DSD decoding
Using the USB HD input direct DSD playback is supported using the DoP Standard 1.0 with
0xFA / 0x05 markers. Please see the playback software manual for more details on
configuring DSD support.
!18
Balanced analogue outputs
You need to connect the analogue outputs on the back of the Red Reference to a pre-amplifier,
which in turn will feed a signal to a power amplifier in order to drive your loudspeakers. There is
a pair of balanced XLR outputs, which will drive a 68Ω load.
connecting to your pre-amplifier
Use the XLR style output connectors to connect the Red Reference to the XLR style input
connectors of any model of Chord pre-amplifier. Ensure that you connect the left output on the
Red Reference to the left input on the pre-amplifier. Also the right output should be connected to
the right input on the pre-amplifier.
!19
RIGHT LEFT
Unbalanced outputs
You need to connect the outputs on the back of your Red Reference to a
pre-amplifier, which in turn will feed a signal to a power amplifier in
order to drive your loudspeakers. All Chord equipment is designed to
be used with balanced connections to maximise audio signal quality.
However there is also a pair of unbalanced outputs as well in case your
pre-amplifier does not have balanced inputs.
connecting to your pre-amplifier
Use the phono style output connectors to connect the Red Reference to
the phono style input connectors of your pre-amplifier. Ensure that you
connect the left output on the Red Reference to your left input on your
pre-amplifier. Also the right output on the Red Reference should be
connected to the right input on your pre-amplifier.

Trigger Outputs
The Red Reference features two trigger outputs that can be used to remotely trigger other
Chord equipment. The external trigger should be connected via a standard 1/8th inch /
3.5mm (mono or stereo) jack plug to the socket fitted to the rear of the unit.
The Red Reference should be switched off, the trigger lead inserted, then the unit switched
back on.
The connections are as follows:
0V / Ground
The tip of the plug is the +5V to +12V dc connection, the centre and rear connection are the
0V or ground connection.
IR Control
The third socket on the rear panel connects to the IR remote control receiver within the Red
Reference. When using room control systems you can connect the remote signal discretely
to this socket rather than using an external IR repeater stuck to the front panel display.
