Perhaps I've set the xtant input gain too low? Based on the xtant manual:

I've tried input gains of -10dB and +10dB. Output gains set at 1/4. Using balanced input, RCA outs from the MS-8.

Make sure there is a signal at all coming from the MS-8. Some have failed that way...(didn't you have issues with that before?).
