Table 70: Auxiliary Audio Connector Pin-out
Auxiliary Input Connections
Auxiliary audio, such as encoded tones from a paging encoder, may be transmitted over
the selected channel using the Auxiliary Input connections. This input bypasses the AGC
circuit for the other two microphone audio inputs. When connections 5 and 6 are shorted
together, the audio present at connections 3 and 4 is transmitted over the selected channel
(see
).
Desk-Microphone Connections
A low-impedance, dynamic element, desk-microphone may be connected to the console at
AUX audio connector Pins 7, 8, 9, and 10 as shown in
. Pins 11 and 12 may
connect to a microphone that includes an integrated “monitor” switch.
Footswitch Connections
A foot-operated PTT switch may be used, allowing operators free use of their hands. A
foot-operated PTT switch for gooseneck microphone operation should be connected
between connections 13 and 14. In addition, a dual position footswitch may also be used to
operate the Monitor function. The contacts of the monitor footswitch should be connected
between connections 11 and 12 (see
).
Recorder Connections
The console supplies a 600-ohm, 0
-
dBm differential output for connection to a logging
recorder. The output is a summation of the microphone transmit audio and the Select
Signal
