Picked up this Toshiba RT-9990 from Chris......Great sounding box, but I really haven't played with it much. Looking for some info on what these controls do.
First, next to the volume knob are a couple of toggle switches. Other than FM and AM, what are the other choices?
Also, next to the mic-mix knob are these 2 toggle switches. Anyone know what they do?
