DESCRIPTION  
D96AU483C  
The TDA7464 is a volume tone (bass middle and  
treble) balance (Left/Right) processorswith stereo  
SRS and voice canceller for quality audio applica-  
tions 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 ma-  
trix. 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 ac-  
complished by serial bus.  
Thanks to the used BIPOLAR/CMOSTechnology,  
Low Distortion, Low Noise and DC stepping are  
obtained.
