The power which has allowance in basic thought in
tone-quality serious consideration, and the Integrated Amplifier which gave the
tone control functionality.
The dual transistor with high stability to
which the property was equal is adopted as an output stage, and circuitry is
made into the whole page hardwired-connection pure complimentary scheme.
Moreover, a distortion harmful from low-pass to a high region is pressed down by
supplying +-2 power source to all the circuitries.
source was used and the it1 noise generated at the time of a switchpoint
switching is reduced.
The two-step hardwired-connection circuitry which
combined the low-noise transistor and the part selected carefully is used for an
equalizer part, and it has become a low-noise and a low distortion.
tone control part has adopted the it1 step type. Moreover, the gentle property
has been acquired by two-step hardwired-connection tone amplifier and CR type
tone control circuit.
The mic mixing circuitry in which level adjustment
is possible is carried.
The voice of the stereo source and a mic is mixed,
it can play, and the mixed voice can be taken out from a sound-recording
The electronic circuitry and the protection network by
relay are adopted.
A push-button type selector, a row / high filter, a
loudness, a muting, the tapes monitor, the mode switching, the headset jack, and
the mic jack are carried.
