Auxiliary audio input (optional) (standard as of module No. 471)
The auxiliary audio input permits audio input from other equipment in the aircraft. This input can only
be heard, however, in the RX mode. The possibility of circuiting two units together finds application in
aircraft having, for instance, only one transceiver and one NAV receiver. When using the auxiliary
audio input, a 680
