Hello Graham,

Leaving the channel faders up when powering on/off the mixer will not hurt anything. NOTE: Be sure that the power amp is off before turning the mixer on or off to avoid damaging the speakers.

That being said, it is always best to lower all faders and zero the pots (knobs) when the mixer is not in use. Leaving a potentiometer in the same position over time can create a little oxide build-up that can cause the potentiometer to not work smoothly and cause scratchy noises when the fader or knob is passed through that area. Granted it is a pain to have to readjust the mixer each time, but it is a very good preventative measure.

Best Regards,

Dave
