1.GENERAL DESCRIPTION
TEAC's A-5300/5500 are high quality stereo tape decks, representing
a New Generation in the design and construction of recording equip-
ment. With DC reel motors and a Direct-Drive Servo-controlled DC
Motor-Capstan, all controlled by Integrated Circuit (IC) Logic Cir-
cuitry, these decks provide highly reliable operation at greatly
reduced noise and heat levels. With almost all relays replaced by
Logic Circuits, transport control is quick and positive, governed by
6 calculator-like buttons on the control center. Both models have
advanced electronics and the 5500 includes built-in Dolby * "'B'' Noise
Reduction circuitry.
