I’m completely stumped. Somehow Input Ch 4 is killing its input signal by 15 dB. What’s worse, it clips the signal
starting at -15 dB (compared to where Ch 3 clips), but the Ch 4 clipping LED does not indicate clipping.
I use Ch3 Ch4 as a stereo input to my synthesizer, but it’s effective only passing thru Ch 3 to recording and output.
Any ideas what could be wrong? I tried restoring to the initial settings (in UR44 dsp44fx program), but no help there.
I’ve had the unit a little less than 3 years.
