    4-CH OUTPUT STEREO AUDIO PROCESSOR WITH 3 STEREO INPUTS AND TONE/VOLUME CONTROL

    The SC7313 is a volume, tone (bass and treble), balance (left/right) and fader (front/rear) processor for quality audio applications in car radio and Hi-Fi systems. Selectable input gain and external loudness function are provided. Control is accomplished by serial I2C bus microprocessor interface. The AC signal settings is obtained by resistor networks and switches combined with operational amplifiers. Due to the used CMOS technology, low distortion, low noise and low DC stepping are obtained.
