The TDA7464 is a volume tone (bass middle and
D96AU483C treble) balance (Left/Right) processors with 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 ponents and surround specification. Control of all the functions is ac- sound by using phase shifters and a signal ma- plished by serial bus. trix. The AC signal setting is obtained by resistor Thanks to the used BIPOLAR/CMOS Technology,...
