Used in high-quality stereo cassette deck operating from AC line or battery. Provides three preset gain positions (10, 33, and 100) to meet amplification requirements of practically all types of microphones used with tape recorders. Recording input of cassette deck provides only enough gain for re-cording from audio amplifier or radio tuner delivering 50-100 mV at fairly low impedance, hence is not suitable for microphone input. Article gives all other circuits of cassette deck and describes operation in detail.-J. L.
