check the bypass button on the front
Check the rear inputs with a line-level source. Then contact support@fractalaudio.com
Check I/O menu, input 1 source too--if it was switched to digital this would happen.
Results from the RMA:
Support says "both converters were blown".
They said it could happen if you take an amplified signal into either the inputs or outputs. Funny as that was NOT my case. I've not moved my Ultra in the rack for over 2 years & the only connections made each time are guitar to input, amp out to cab in, and midi in to midi out on pedal.
$150+ the $2700 I just spent on the II. BAH! B A H I say.
