The ID is CLV-A900R.

I only managed to find user manuals for the Advent AW820 and AW810,
but I'm not sure if they match your model:

I also turned up a blank when I searched for RadioShack circuits for
cat #400-1463 and #40-1463 at the FCC database.

Thanks. I have the user manuals, but I need to modify the circuitry &
was hoping I wouldn't have to sort it out the old fashioned way. No
big

deal. At some point, tracing out the necessary signal paths is
quicker than tracking down the schematic. I think we've hit that
point.

Wireless speakers usually have a matching transmitter. Do you have
one?

Yes, but the modifications I want to make are to the audio circuitry in
the speakers.

My idea was to open it up and see what you can figure out from the
transmitter circuitry. Also you could run the transmitter and see what it
is transmitting. (maybe you have a spectrum analyzer or a emc reviewer)
