Commentary
A pre-main amplifier that adopts a pure complimentary service OCL circuit directly connected to all stages.
A low-noise transistor and resistor improve the SN ratio of the preamplifier section.
Equipped with a loudness switch.
Equipped with a wide range power meter.
Mixing recording is possible by using the separately sold microphone mixing amplifier MX-1.
