Basic structure

With the DA source button you select the source for the built in 8/2 mixer and for your 
analog outputs. You can choose between the input selected on the AD-D button or any of 
the digital interfaces. If a valid digital signal is present the green “Carrier” LED will light up.  

If you have installed a ProTools Mix 24 compatible I/O card you have to choose this 
interface as Multi 1 or Multi 2.  

With the AD-D source button you can choose the input (for 2 channels at a time) which 
will be availably as a digital signal on all digital multi-channel outputs with the sample-
rate, dither and sync selected at the sample-rate, dither and sync buttons. 

If you choose an analog signal the converter will work as an A/D converter.

If you choose a digital signal the converter will work as a sample-rate and/or a format 
converter. If the incoming digital signal is not in sync with the converter it will be detected 
and the signal will be sample-rate converted.

If a valid digital signal is present the green ‘Carrier’ LED will light up.
