Commentary
A 4-channel rear amplifier consisting of a Sansui QS synthesizer / decoder section and a rear main amplifier section.
You can enjoy 4-channel playback by connecting it to a tape monitor switch of your own amplifier such as a separate type, modular type or receiver.
Equipped with a function switch that allows you to you to choose the effect that matches the difference in the music number and composition of the source and the difference in the recording method.
The rear speaker can be arranged in two ways (2-2 system, front 2-2 system) depending on the number of songs and composition by using the switch.
By switching the switch, you can enjoy the 4-channel effect by comparing 2 methods.
A slide type is used for front and back volume adjustment.
Equipped with a stereo main amplifier using silicon transistors.
The synthesizer and decoder uses a pure electronic circuit system that employs an IC originally developed by SANSUI.
