CS DATA Button & LEDs
This button will select the type of channel status bits to be
embedded in the digital audio output – either professional
or consumer. The channel status type can be set directly or
can follow the digital audio input source.
BITS Button & LEDs
This button sets the bit depth of the RB-ADDA2 Analogue
to Digital conversion to 16, 20 or 14 bits. The bit depth is
reflected in the appropriate channel status bits in the digital
output stream.
D/A SOURCE Select Button & LEDs
This button will select the digital audio input source
for the RB-ADDA2 Digital to Analogue conversion and
will also set the level of the output signal corresponding
to full-scale digits to +12, +18 or +24dBu. The D/A
SOURCE select button will flash if the digital audio
source selected is not present.
Reset Button
In the unlikely event that the RB-ADDA2 unit fails to respond, press
the reset button to reboot the unit (see Fig 2-1 for location).
