AA-920
Stereo Tuner Amplifier
The AA_920
top quality FM/AM MPX stereo tuner amplifier features multiple connections and
controls and three separate speaker systems which can be utilized individually
or two systems simultaneously. Step type volume control with prest facility,
bass and treble controls for even and precise adjustment. Efficient design
includes signal strength tuning meter, mode indicator lamps and ideally
positioned controls for easy operation.
