Matty,
Thank you for the information. I have a couple follow up questions:
1. Are the AMP OUT and MAIN OUT/LEFT MONO equivalent? Since you use the latter, I'm inferring a difference between the two. Is there? (I have figured out--the hard way--that if you use the MAIN OUTs, you need to pay attention to the volume knob. Using AMP OUT, the volume knob seems to do nothing if not running external effect/pedal loop, which I'm not.)
2. If I wanted to use stereo, would I use an adapter/cable that combines the 1/4" left and right main outputs into a single XLR for the house connector, or would left and right each need to go to separate XLR house connectors?
Thank you again!
