Subject: Audio Mic and Phone Lo connections
I am wiring a SL-40 and a G420W into a PMA5000EX.
The SL-40 has a mic ground on pin 7 of the connector.
The G420W has a com mic audio low on pin 18 of connector P4002.
On the PMA5000EX wiring diagram connector J1 there is no pin used for the com mic
audio low/ground.
Should I connect the SL-40 and G420W audio grounds and mic grounds to a common
point at the audio panel?
Thanks,
Mike Cingari
