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
SDIP42

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.
