5.5 Digital Audio Cabling
A digital audio cable must be connected between each Amplifier and the
Matrix Switcher. Use Cat-5 Unshielded Twisted Pair (UTP) data cable, and
appropriately wired RJ45 plugs and wall plates.
Since Cat-5 cable may be used for several purposes within the same
installation, it is recommended you use green cable for digital audio
connections, pink for C-Bus and blue for Ethernet. Wall plates should be
labelled to differentiate between the various RJ45 connection types.
Colour coding of sockets is recommended.
Avoid laying digital audio cable alongside mains cable, as electro-
magnetic interference (EMI) can disrupt the signal. An individual Cat-5
cable which connects a digital audio output to an input should not exceed
45 metres. This is illustrated in
Figure 10.
