2.5Auxiliary 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 680Ω resistor must be switched to GND. When circuiting units together, 100Ω decoupling resistors must be included (see following diagrams). Output of the audio listening amplifier requires an audio input voltage of approx. 1 V/600Ω .
