Signal Name
Definition
5, 6
External Radio 2 AUD
Hi/Lo
These pins provide an audio output to the audio system from
External Radio 2. Assignment of a transceiver to External Radio
2 is a programmable option, default is to the audio
management unit. This output is capable of adjustment from
2.5Vrms ±0.25 Vrms (10mW) to 7.75 Vrms ±0.25 Vrms
(100mW) into a 600 Ω load (except as noted)
7, 8
Audio 3 Out Hi/Lo
These pins provide an audio output to the audio system from
Transceiver 3. Assignment of a transceiver to Audio 3 is a
programmable option, default is to the transceiver in slot 3.
This output is capable of adjustment from 2.5Vrms ±0.25 Vrms
(10mW) to 7.75 Vrms ±0.25 Vrms (100mW) into a 600 Ω load
(except as noted)
9, 10
External Radio 1 AUD
Hi/Lo
These pins provide an audio output to the audio system from
External Radio 1. Assignment of a transceiver to External Radio
1 is a programmable option, default is to the audio
management unit. This output is capable of adjustment from
2.5Vrms ±0.25 Vrms (10mW) to 7.75 Vrms ±0.25 Vrms
(100mW) into a 600 Ω load (except as noted)
11
Audio 3 PTT IN_N
Grounding this pin enables Audio 3 Push-To-Talk function.
