Just purchased a new Denon x1800 that arrived this afternoon, brand new out the box I set it up and updated the firmware but I seem to have a problem with all 4 channel faders - though they work they all seem to only cut in after going up around 80% then from 80% the cut in audio volume gain is really fast.
You can barley hear it at 80% so nudge them up a little and the increase in volume is far to fast, they just seem far too delicate and all top end.
