Factory Specs;

The highest-class receiver announced as 4 chFM/AM synthesis stereo amplifier.
2ch stereo can be enjoyed and it has become the design by which the output at the time of switching from 4ch is doubled. The SEPP-ITL-OTL circuit is adopted as a power amplifier part.
Furthermore, the power supply stabilization circuit and the protection circuit are carried. A preamplifier part considers it as a whole page direct connection circuit, and builds in NF type tone control.
Moreover, discrete and CD-4 system, SQ, and the decoder amplifier for four channels of the regular matrix (RM) system are incorporated.
Furthermore, surround balance can be operated by remote control, and also 4ch dubbing jack is equipped and an impedance level meter can be attached. To the front end of FM tuner part, it was considered as FET and the two-step RF magnification circuit using a frequency straight line type Joint 4 variable condenser, and the disturbance exclusion capability to have excelled is acquired.
Furthermore, the ceramics filter and four-step direct connection IC were used for IF stage, and IC and a 15kHz low pass filter are adopted as a MPX circuit. In AM tuner part, a triple variable condenser is adopted as RF stage, and the ceramics filter is adopted as IF stage. Preset volume is carried.
