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
