Description
 
Tuner amplifier which unified amplifier and a tuner.

An operationality and a feeling of an operation are valued, it is designed, and consideration is made each switchpoints.

The light emitting diode signal indicator is carried.

The mic mixing circuitry and the loudness switchpoint are carried.
