External PA Operation
The audio to the recorder (REC_AUDIO) is an unbalanced low impedance signal at a fixed level of
300mVrms. A logical output (REC_ACTIVITY*) is provided to indicate when activity is on the
recorder output audio pin. When there is activity on the recorder output audio pin, it will be pulled to
less than 0.8VDC. Refer to the below table for more information:

• Receive audio - without tones
• Receive audio and Transmit audio - without tones
• Receive audio and Transmit audio - including tones (ex. Keyfail and Trunking)
• Disabled

4.21.1 Firehouse Day/Night switch
The Consolette supports a feature called Auxiliary Control. This is where a button press on the front
panel of the Consolette can control the activation of a general purpose output on the rear of the unit.
The general purpose output can be connected to an external relay that could be used to mute/
unmute an external PA system. A typical use case is in a firehouse where the PA system needs to be
turned off in the evening and then re-enabled during the day.
Refer to the APX 7500 CPS Help Screens for VIP Outs for additional details on how to configure the
transceiver for Auxiliary Control capability or
section 3.7.1.1
of this manual.
