4.7.2 Transceiver, remote configuration
In a transceiver setup for remote configuration, the audio is fed into the transmitter and the received
audio is output from the receiver on the 600 ohm lines.
The line can either be a 2 wire (2W) audio line connected to the transmitter only, or a 4 wire (4W)
interface connected to the transmitter and the receiver units.
