DESCRIPTION

The TDA7465 is a volume tone (bass middle and

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 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. An Extra Mix Input is available to

connect microphone for KARAOKE feature.

Control of all the functions is accomplished by se-

rial bus.

Thanks to the used BIPOLAR/CMOS Technology,

Low Distortion, Low Noise and DC stepping are

obtained.
