Description
@
The Integrated Amplifier which adopted the whole page direct connection pure complimentary OCL circuit, and realized power of 40W+40W.

Adopting low noise type a transistor and resistance, the signal to noise ratio from the phone input of a preamplifier part has become 70dB.
Moreover, the engine performance of an equalizer is also 170mV (RMS) of maximum permissible inputs, and RIAA deflection. }0.5dB is realized.

Distortion is 0.3% in the time of 40W output. Usually, the low distortion in the volume heard at home is planned, and 0.05% and a low distortion are saved with 4W output.

Loudness switch loading.

The wide-range power meter is carried.

It is using optional microphone mixing amplifier MX-1, and mixing recording is possible.
