Commentary
New class A amplifier with built-in microphone mixing circuit with echo.
In addition to a synchronous bias circuit that eliminates switching distortion and crossover distortion, it is equipped with a linear feedback circuit that realizes 0 theoretical distortion.
Equipped with FL peak power meter, can display from 0.001W to 100W by 2 range selector switch.
Equipped with a microphone mixing amplifier with a built-in BBD electronic echo circuit.
It also has a mixing recording switch that can output the mixed sound as it is.
Equipped with 2-tape monitor function.
Equipped with an input selector with indicator.
