RD-XS24 has three line
inputs and one RF input from
tuner. These analog signals
are converted to digital data
by audio AD onverter(AIC03).
The signal passed AD con-
verter transmit to main
board which have Dolby
Digital encoder/decoder.

RD-XS24 has two stereo outputs and one digital output(coaxial) Decoded
converter(AIC04), then filtered and amplified AIC05(OP-amp), and finally
ouputted via RCA terminals and Scart terminals. The digital audio signal is
