G. "Auxiliary" audio input
The AF-AUX (P1/4) auxiliary audio input enables the switching of audio si-
gnals from other equipment in the aircraft. The switched-in audio signals
can, however, only be monitored in the reception mode. The facility to switch
two units together will be used particularly in those aircraft which are fitted
with an Transceiver and an NAV receiver. An audio input voltage of 1 to 8 V,
600 Ohm is necessary for modulation of the audio audio amplifier (can be ad-
justed in the "Service" mode).
