The Integrated Amplifier which carries sufficient
power and abundant functionalities.
The dual transistor with high
stability to which the property was equal is adopted as an output stage, the
power stabilized over the wide band has been obtained, and circuitry is made
into the low distortion whole page hardwired-connection pure complimentary
Furthermore, by supplying +-2 power source to all the circuitries, a
distortion harmful from low-pass to a high region was pressed down, and the
stable operation has been obtained. Moreover, +-power source is used and the it1
noise generated at the time of a switchpoint switching is made to reduce.
The two-step hardwired-connection circuitry which combined the low-noise
transistor and the part selected carefully is adopted as an equalizer part, and
it has become it with the low distortion by the low-noise.
control part has adopted the click stop type, and has acquired the gentle
property by two-step hardwired-connection tone amplifier and CR type tone
The mic mixing circuitry is carried. The mixed voice
can be taken out from a sound-recording termination, and also can perform a
coordination of mic level.
The electronic circuitry and the protection
network by relay are carried.
The one-touch push-button type is adopted
as an input selector.
A high filter, a loudness, a speaker changeover
switch, a tapes monitor, a mode switching, a headset jack, mic level, etc. are
