However, for practical reasons and future system maintenance easiness, we do strongly
recommend using the FAR Link
TM
network, even if no remote control is required.
4.2.3
Multi-channel 5.1 System
A 5.1 digital setup does require 3 AES/EBU cables, each of them carrying 2 audio
channels. The channels are usually grouped in Left & Right, Center & LFE and Surround
Left & Right. We will assume in the following setups that this is the default channel
assignment.
There are multiple ways to connect a 5.1 system. The cabling topology depends a bit on
the requirements.
If a minimal number of cables shall be used, the solution is to use the FAR Link
TM
network to carry audio and control messages. The audio streams will be sent to the
speakers by the mean of 3 XLR cables, connected to the DIGITAL IN connector of the
LEFT, CENTER and SURROUND LEFT speakers. As we use the FAR Link
TM
to carry the
digital audio, the cabling sequence does matter but is not unique. What is important is
that the speakers sharing the same IEC60958 stream (AES/EBU) are contiguous,
network wise.
The following Figure shows one possible way to easily connect the 6 speakers together.
Note that the cabling order of a speaker pair (LEFT & RIGHT, CENTER & LFE or
SURROUND LEFT & RIGHT) does not matter, as long as the speaker of the pair that gets
the AES/EBU cable is first in the network chain.
The signal routing is achieved by the mean of the Input and Output speaker parameters.
