Hello everyone -

I've had my Firestudio 2626 for years and it has always worked great. Today I decided to connect an ART Digital MPA (http://artproaudio.com/discontinued_products/discontinued_products/product/digital_mpa/) via ADAT to get 2 extra channels of inputs.

Everything is routed fine except I get some digital distortion and noise on the 2 ADAT channels. I've tried every combo of slave/master, with BNC cable/without, input/output levels, etc I can think of. Am I missing something? Or are one of the units just going bad?

Running on a 2012 Macbook Pro (OSX 10.6) and recording in Reaper (noise and distortion is heard in both Universal Control and Reaper).

Thanks!

I'm sure you've checked, but do the sample rates match?

Yep - sample rates match (and I have tried them all).

Thanks!
