3.3.2.1 DAC analogue output
The same Digital to Analogue Converter (DAC IC) as applied
in the conventional CD player will be used in the CD-Audio
Recorder/player.
3.3.2.2 Digital output
From Decoder CD60 is used the DOBM signal (IEC958
format) to connect this signal via an electronic switch to the
digital output connector.
3.3.2.3 Monitoring
Monitoring of the input signal at I7S level is possible via the
direct digital out and analogue out generated from the same
I?S datapath information. However it is not possible to read
and write at the same time the disc information. That's why
the "monitor" signal does not proof the written signal.
