The SC7314 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.
Input multiplexer:
4 stereo inputs
Selectable input gain for optimal adaptation to different sources
Four speaker attenuators:
4 independent speakers control in 1.25dB steps for balance and fader facilities
Independent mute function
All functions programmable via serial I2C Bus
Loudness function
Volume control in 1.25dB steps
Treble and bass control
Input and output for external equalizer or noise reduction system
