audio processor which incorporates volume, tone(bass and treble) ,

balance(left/right)and fader(front/rear) into a single chip. Selectable

input gain and loudness function are provided to build a highly

effective electronic audio processor having the highest performance

and reliability with the external components. The AC signal setting is

obtained by resistor networks and switches which are set by

programming serial input signal via I

processes are utilized for low distortion, low noise and low DC

stepping.
