The Linedriver handles all analog input- and out-
put-signals for the Digital Carradio Signal Proces-
sor TDA7501. The device contains four inde-
pendent input multiplexers to select the sources
for the DSP鈥檚 four AD-converters. Four additional
gain stages allow an adaptation to run the ADCs
in best S/N condition.
The six outputs have independent volume stages
with a large dynamic range. Using a 12V-supply
the outputs are able to drive up to 4Vrms .
