I just purchased a used Pro-652 on ebay and everything works fine with the exception that the audio output is very low compared to my GRE PSR-600 which theoretically is the same radio. The audio quality is excellent but the volume is low even with an external speaker. I did notice that in the manual there is a note on page 11 indicating that an amplified external speaker is needed which I found surprising. Is this normal with the 652?
I obviously could use an amplified speaker but it would be nice to avoid this if possible. For reference, I have reset the unit to the factory defaults and I have scanner on its side so that the internal speaker is not blocked. I am listening to both a P25 system and conventional channels. I am also using ARC500PRO software for programming.
Does anyone have any suggestions or access to a schematic?
Thanks,
