Description
@
The Integrated Amplifier which carried the video input and carried out AV correspondence.

The original power amplifier which investigated high speed magnification in high purity unreturned [ of 0dB ] is adopted.
A power stage canceled dynamic distortion generated by signal return, and has improved the dynamic characteristic while it loses the influence of the back electromotive force from a speaker by separating electrically a voltage magnification stage and an electric power magnification stage.

By adoption of the pure dynamic power supply circuit by a 2-2 system block capacitor, generating of dynamic IM distortion (inter-modulation distortion) was suppressed, and the quality on Hearing impression is improved.

In order to eliminate invasion of an external noise ingredient, the power-source part and the main signal system are made into the chassis structure separated through a radiator.
Moreover, while adopting the input selector by an electronic switch and arranging a signal line ideally, leading about of wiring is lessened and simple signal courses, such as shortening a wiring wire, are formed.

The processor loop printer is equipped.

Two video inputs by the complimentary push pull circuit are carried.

The Subsonic Filter only for Phono is carried.

The high-speed protection circuit is built in.

Real-time tone control is carried.
