Digitally controlled audio processor with surround sound matrix and voice canceller

General Description:
The TDA7430/TDA7431 is volume tone (bass middle and treble) balance (Left/Right) processors voice canceller for quality audio applications in car radio and Hi-Fi systems. The reproduce surround sound by using programmable phase shifters and a signal matrix. Control of all functions is accomplished by serial bus. The AC signal setting is botained by resisstor networks and switches combined with operational amplifiers.
