Resolved: 8pre Clipping From Guitar Amp

[WildVines]

I have a 8pre and I'm getting distortion that sounds like clipping coming from the output of my guitar amp. It seems to only be present in the main outs to my studio monitors, not the headphone out. I tried using a direct box Hi to Lo Z, but that didn't help. Everything was connected to my previous interface, a Roland Octacapture, the same way without any problem. Any help would be appreciated.

From the manual:

■ Eight 24-bit analog combo XLR/TRS mic/
instrument inputs with preamps, each equipped
with individually switchable 20 dB pad…

Mismatched sample rates cause distortion and
crackling. If you hear this sort of thing, check the
sample rate settings in your hardware and here in
MOTU Audio Setup.

Not sure if either is the problem other than I would look there first.

Thanks Mike for the response. I have the main outs of the 8pre going into an amp with passive speakers attached. Looks like the problem was that I had the output level on the 8pre all the way up. When I lowered the main out level the distortion went away.
