Automatic Summing - from NDSP - "The QC won’t automatically sum to mono if you connect only one output. You need to set the output of the preset to mono in case you want to connect only one XLR. "

This sucks because if you get somewhere with only 1 XLR for you to use, you have to change every preset 1 by 1
