The Integrated Amplifier which avoided coloring in all respects of
the engine performance, a function, and a design, and was developed more
The pure complimentary OCL circuit of one step of
differential is adopted as circuit composition, and change of sound quality is
suppressed by simplifying the course along which a signal passes as much as
Moreover, the margin was given to all the parts and especially the
power transistor has adopted what raised Pc40W and a rank. Moreover, the
somewhat larger thing than the conventional thing is adopted also about a
In order to be able to drive a speaker in the best state
certainly, the drive of the speaker of low impedance is also taken into
consideration and designed.
it is possible to have the separation terminal of a preamplifier output
and a power amplifier input, and to come out and for even a slide switch
to use it, dissociating
The high proof-pressure
low noise silicon transistor is adopted as an equalizer circuit.
Interface Connector input terminal and two REC terminals are carried.
BAX type modification is used for tone control. The variable system is a
click stop type of 11 positions.
Moreover, loudness control and a high cut
filter are carried.
There was a wood case as an option option.
