The stereo receiver corresponding to 4ch developed
making full use of the semiconductor technology and the circuitry technology.
The four RM-SQ matrix circuit is built in.
It is also possible
to have adopted the OCL circuitry as a power amplifier part, and to double an
output by the BTL circuitry at the time of 2ch.
FET is used for FM tuner
part.
The pair mic mixing circuitry is carried.
