The SAA7706H performs all the signal functions in front of
the power amplifiers and behind the car radio tuner
AM and FM outputs and the CD, tape and phone inputs.
These functions are:

Some functions have been implemented in hardware
(FM stereo decoder, RDS-demodulator and
FM Interference Absorption Circuit (IAC) and are not freely
programmable.
Digital audio signals from external sources with the Philips
I
or SPDIF format are accepted.
The big advantage of this SAA7706H device is the ‘dual
media support’; this enables independent front seat and
rear seat audio sources and control.
