Around early 1970
(japanses translation)
Commentary
4ch Amplifier equipped with a Sound Field Composer. I am equipped with a Sound Field Composer circuit where you can enjoy the atmosphere of 4ch in 2ch source. By a device to reproduce the pseudo 4ch, is output from the speakers of another reverberation only component that is included in the 2ch source, this circuit is aimed to reproduce the sense of reality.
It uses a 2ch-4ch complementary circuit by BTL Type of actuation in the MCA-V7, to drive each speaker in the SEPP circuit four sets 4ch playback, I get a high-powered by BTL connection 2ch time. I have adopted a quasi-complementary ITL · OTL circuit to circuit configuration. In addition, with the aim of noise reduction by adopting a low-noise silicon transistor. Equalizer circuit has become a two-stage, and is stopping the transistor noise by using a PNP transistor in the first stage. 4ch and two inputs, it is equipped with the 4ch recording and playback terminal.
It is equipped with an pre-out main-in terminal of 4ch, it can be used independently of the main amplifier and preamplifier.
