Audio Output Connections - CAMBRIDGE CXU User Manual

Audio output connections

Do not plug in the mains power lead or turn the unit on until all connections
have been made.
Three types of audio only connection can be made between the CXU and
your stereo/AV system:
1 Separate Analogue Stereo
2 Digital Audio
3 Analogue 2 ch/5.1/7.1

Separate analogue stereo

The analogue stereo outputs should be used for play back of CDs, DVDs
etc in stereo through a conventional amplifi er or AV receiver with analogue
stereo inputs.
Analogue stereo is also usually the best connection method for listening to
CDs and other stereo discs for best possible sound quality. It is often a good
idea to connect both the analogue stereo outputs (for CD playback) and
digital audio outputs or HDMI (for surround sound decoding) at the same
time.
To connect an analogue stereo system to the CXU, use stereo phono cables
(stereo 2RCA-2RCA).
Digital audio
2
The digital audio outputs should be used to decode the surround-sound
soundtracks of BD/DVDs with an external AV Receiver (Note: Digital
output must be set to "RAW" in the Audio setup page). The CXU sends an
undecoded audio bitstream to the AV Receiver for decoding into 5.1/7.1 etc.
Note: The latest HD audio types, SACD and DVD-A cannot be output over
SPDIF/TOSlink and an HDMI connection must be used for these.
Either a 75ohm coaxial cable designed for digital audio or a TOSlink fi bre
optic cable should be used (only one at a time).
Note: It is also possible to output stereo digital audio from the Digital Outputs
for recording on conventional CD-R/MD etc. machines, see section on CXU
setup.

Speaker diagram shown for 5.1 channel setup. For 7.1 add two rear speakers.
Note: It is also possible to make an HDMI audio/video connection which
carries both audio and video in the same cable. See later section.
However, when making an HDMI connection i.e. to an AV receiver, it is also
often preferable to make an additional audio connection as well for CD and/
or SACD/DVD-A playback.

The CXU is also capable of decoding Surround-Sound soundtracks itself and
outputting these as analogue Stereo, 5.1 or 7.1 depending on the settings in
the Speaker setup page in the CXU setup menu.
For 5.1, connect to an AV receiver or amplifi ed speaker system, use 6 x
phono/RCA cables.
For 7.1, connect to an AV receiver or amplifi ed speaker system, use 8 x
phono/RCA cables.
