How have you been using the DAC until now? What method of connection between computer and DAC?
I don't know what dig thru is, you should be using line out mode.
I honestly just got everything, and I'm relatively new to all of the equipment, although learning.
I was under the impression that digital through (labeled as dig thru on the ADI-2 PRO FS) would take the USB input signal (the audio), and then send out the audio out of the unbalanced audio outputs in the back of the amp. However, it doesn't appear to work.
The ADI-2 Pro came with a breakout cable which contains female coaxial SPDIF (RCA) that can connect into the back of the unit as well, so I'm not sure if I should use those RCAs instead of the TS outputs?
