Preliminary specification
Car radio Digital Signal Processor (DSP)
SAA7705H
The DSP contains a basic program that enables a set with:
AM/FM reception
Sophisticated FM weak signal functions
Music Search System (MSS) detection for tape
Dolby-B tape noise reduction system
CD play with compressor function
Separate bass and treble tone control and fader or
balance control additional to the equalizers.
