Commentary

A pre-main amplifier using LTP transistor developed with Hitachi semiconductor technology in pursuit of low distortion.

Pure complimentary service outputting circuit is adopted.

It is equipped with a circuit breaker to protect the circuit and speakers in case of trouble.

A built-in microphone amplifier allows mixing with other audio sources.
