JVC - JA-S22 - DC Integrierter Festkörper-Verstärker

Pre-main amplifier that uses DC power amplifier.

The power amplifier section is fully DC, and transmission performance from the DC band to the ultra-high band is improved by eliminating large-capacity capacitors from the NFB loop.

Stability is ensured by the current mirror input circuit.

We have carefully studied circuit components and printed circuit board patterns to reduce the distortion factor of all circuits.

The front panel is equipped with two tape terminals and a logarithmic compression type power meter.

Equipped with a two system speaker selector that can be driven in parallel.

Equipped with a relay type three Oshige point protection circuit.

Equipped with a subsonic filter to cut low-frequency noise.
