2.6.1.1. Identifying Audio Connections (4-Channel Discrete)
In a 4 channel system, there are two physically identical encoders in the transmitter unit
and two corresponding decoder modules in the receiver unit (see Fig. 2-2). The
modules are identified with an ID # on the rear panel (ENC1, ENC2, DEC1, DEC2). The
audio configuration of the module (Linear/Compressed/Data Rate) can be checked on
the Test Data Sheet supplied with the units.
