Setting and sound quality

Bal (Left-right balance adjustment), Level (Input level
adjustment), Gain (Gain selection) are all selections related to
sound output. These settings and the position of the VOLUME
knob are detected comprehensively by a micro computer and
wholly controlled by a singular volume control amplifier.
It is therefore different from normal amplifiers where sound
signals pass through several circuits. In this design
implementation, there is no deterioration in sound quality
caused by any of these the settings.
