On my 7.1 Denon AVR 1912, I seem to have to have the volume turned up quite considerably for the audio to be loud enough... The audio also shows up as neg decibels (is that standard?). I've adjusted the channel levels to their highest levels now, which has helped, but that seems a bit janky considering that the levels are supposed to be set by distance needs and now are all just set high. I'm not saying the sound is bad, because it isn't, it just seems a bit counterintuitive to me. Any ideas, thoughts or comments to edify me better?
