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
May 1997
