Commentary
This is a pre-main amplifier with enhanced power supply, low impedance power amplifier, and wide range so that various and unique speakers can be driven.
The power amplifier uses a discrete method.
By using a discrete method instead of IC, the advantages such as current margin, freedom of parts and circuits, and heat radiation are utilized.
It is equipped with a source direct switch that bypasses the tone control circuit and inputs directly to the power amplifier.
You can choose between a direct position that does not use tone control and a tone position that uses the control function according to your preference.
Two tape terminals are installed, one of which is capable of simultaneously monitoring a 3-head deck.
There are two types of speaker jacks, A and B. You can play A/B independently or simultaneously.
The terminal is screw-type and also supports banana plugs.
Equipped with a loudness switch that increases the impact at low volume.
It comes with a RI system remote control that can control not only amplifiers but also CD players, cassette decks and tuners with the RI mark.
Power cord has polarity display.
