Main output defeats monitor output?

sage · Jun 4th 2013

I played a live show a week and a half ago and used the monitor and main out, no problem. Changed absolutely nothing in the meantime, and then went to record a band last night. Monitor out to the cab so he could hear it in the room (live tracking of a six piece bluegrass band, buddy had a gorgeous hand made Weissenborn copy) and when I plugged in the XLR to the main output, the monitor out shut off. I ended up mic'ing the cab with a 57 and it sounded great anyway, but what the heck happened?

Any help would be appreciated.

That's odd as there is no defeating of outputs.
Did you look up the actual monitor volume in the master/output menu when this happened?

Sorted out the problem. My recording interfaces have phantom power. When the phantom power is on, the signal does not go through to the monitor out. When the phantom power is off, no problemo.

But you mean the interface's monitor out then?
How can the interface's phantom power affect the KPA's monitor out?
