GENERAL DESCRIPTION
The SAA7707H performs all the signal functions in front of
the power amplifiers and behind the AM and FMMPX
demodulation of a car radio or the tape input.
These functions are:
Interference absorption
Stereo decoding
RDS decoding
FM and AM weak signal processing (soft mute, sliding
stereo, etc.)
Dolby-B tape noise reduction
The audio controls (volume, balance, fader, tone and
dynamics compression).
Some functions have been implemented in hardware
(stereo decoder, RDS decoder and IAC) and are not freely
programmable. Digital audio signals from external sources
with I
2
S-bus formats are accepted. There are four
independent analog output channels. This enables, in
special system configurations, separate tone and
equalization control for front and rear speakers.
The CDSP contains a basic program that enables a set
with:
AM/FM reception
Sophisticated FM weak signal functions
Music Search detection for Tape (MSS)
Dolby-B tape noise reduction system
CD play with compressor function
Separate bass and treble tone control and fader/balance
control.
For high-end sets with special and more sophisticated
features, an additional Digital Signal Processor (DSP) can
be connected. Examples of such features are:
Noise-dependent volume control
10-band graphic equalizer
Audio spectrum analyzer on display
Signal delay for concert hall effects.
