Hello,

I was wondering, specifically on the "impres" mics, if there is a substantial difference besides audio characteristics from the xts or other mics. Like is there any circuitry that relates to the radio on the more basic mics such as the PMMN4062A? I am asking because even if it didn't help with volume, I would like to use some extra APX mics I received for a few XTS5000 and already have extra accessory pigtails (normally used to replace Commander II's cords).

Thanks for any input.
