DESCRIPTION

The TDA7466 is a volume tone (bass middle and

treble) balance (Left/Right) processors with stereo

SRS and voice canceller for quality audio applications in car radio, Hi-Fi, TV systems.

It reproduces SRS (Sound Retrieval System)

sound by external components and surround

sound by using phase shifters and a signal matrix. The AC signal setting is obtained by resistor

networks and switches combined with operational

amplifiers according to the SRS laboratories

specification. Control of all the functions is accomplished by serial bus.

Thanks to the used BIPOLAR/CMOS Technology,

Low Distortion, Low Noise and DC stepping are

obtained.
