Since I moved it away from my monitors(screens) its running a lot cooler now.
All my problems are user error/ignorance, not the unit. I’ve spent most of today with it ,and have made good progress I think. I’ve only ever used DAW mixers before, so having another “mixer” between my DAW and interface has been confusing.
Thanks again to everyone who has helped with this, much appreciated.
I’m sure to have a few more dumb questions soon, watch this space!!
