Commentary
An integrated stereo AV amplifier with video input / output.
Low impedance load drive capability of up to 2 Ω has been obtained by improving the power stage.
The audio and video signal circuits are separated from the board level, and the two layer structure is strictly shielded to eliminate interference between audio and visual signals.
The video input / output is equipped with a wide-band video amplifier with a 10-MHz passband, which is used in high-grade video selectors, to prevent image quality degradation.
In the power supply section, the analog, video and microcomputer systems are separately wound from the transformer to prevent mutual interference.
The terminal panel is fixed with copper screws to eliminate the influence of high-frequency video signals on sound quality.
Equipped with a remote controller, volume can be adjusted by motor volume and input can be switched.
It is equipped with an Audio Rec Selector, Source Direct Function, and Last Memory Function for timer usage.
