Beautiful and rare technics receiver with possibility of 4 channel rendering. The matrix circuit is built in. This circuit turns a 2 channel signal into a 4 channel signal. This receiver is also suitable for a singer because you can connect 2 microphones but, of course, a tape deck, tape recorder and record player also work fine with this super receiver. This receiver was prized for its sound quality where many receivers from this period could not match it. Really very beautiful and very good sounding receiver for the lover of gorgeous vintage audio or a beautiful sound.
