the PMA7000MS doesn't use knobs at all but employees a computer at each
microphone to automatically adjusting the VOX levels at each microphone.

Hi Mark -- glad you "intruded" here. :-)

A quick question for you -- we have Lightspeed headsets at all four intercom
positions -- a new 25G, a 25XL, and two 15s. It is our experience that the
two front seat positions (with the two newer headsets) are louder in the
intercom than the back two positions.

Obviously it's easy to adjust the headset's individual volume controls to
compensate for this, but is there an adjustment on the PS Engineering unit?
Or should this be accomplished by changing the headset's microphone "gain"?
