I've read the owners manual for the outputs section and can't figure out what I have set wrong.
Monitor output is set to Master mono, monitor volume set at 0.0 db
Main out and monitor out link are both checked
monitor cab off is checked
Monitor output is going into the FX return of an amp. If I unplug the cable from the monitor output jack and plug into the headphone jack it works (though with the cab sim still going obviously)
Any ideas?
