Using Williams Sound’s passive POE injector kit allows the installer of an IR T2 to provide POE power and one of the following three options:
1 channel of balanced line level audio
1 or 2 channels of unbalanced line level audio
RS-232 control and monitoring signal.
CAT5 cable contains four twisted pairs of wires, two of which are used for POE, and the remaining wires can be used for the additonal features.
