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

Dual super unreturned power amplifier is carried.
Moreover, the perfect direct-current composition which does not use a coupling capacitor for all the signal courses between MC input - a speaker output terminal is adopted, and the voltage magnification stage has realized the outstanding slew rate by adoption of the new current mirror circuit of the high-speed transistor use excellent in the high region characteristic etc.
Furthermore, the large-sized pellet power transistor of the fT50MHz multi-emitter structure of Pc200W was carried out in margin 10 minutes, it had it, and expansion of the full operation domain is aimed at.

Generating of low-pass distortion is reduced by setup of the floating circuit which clarified ground electric potential.
Furthermore, by adoption of the "pure dynamic power supply circuit" by an original 2-4 system block condenser, generating of dynamic IM distortion (inter-modulation distortion) which considers ripple current as a cause was suppressed, and the low-pass play is improved.

In order to prevent the noise invasion from the power-source part by the increase in various digital equipment etc., while adopting the newly developed power transformer that carried out special electrostatic shielding processing, the disturbance characteristic is improved by making a power-source part and the main signal system into the structure separated through a heat sink.

direct-current servo system super equalizer of a low noise FET differential amplification input and high-speed operational amplifier use is carried, and RIAA deflection of 20Hz - 100kHz, and }0.3dB has been obtained at the time of MC cartridge use.

The processor loop printer is equipped so that a graphic equalizer etc. can be utilized.

The input selector by an electronic switch is adopted, a wiring wire is decreased, and the simple signal course is formed.

The Subsonic Filter only for Phono is carried.

High-speed protection circuit built-in.
