A general question. The sound level displayed on the box is showing as -33 give or take. Is this normal for this receiver? The sound is fine, I'm just wondering why the minus number?

Hi,The -db thing is a bit of an anachronism these days some receivers give you the choice of changing to a + ('normal') volume range in the menu. IIRC the -db ratings are because an amp is at max. volume at -0db so for example -90db is holding the power back and by going up/down! in -db steps you are allowing more power to flow. I'm sure someone could explain it better but I hope I have helped rather than confused you.

No, the AVR is not at its maximum volume at 0db. The 0db represents the reference level to which the receiver was levelled according to during calibration. You can exceed this, but I'd suggest not doing so because you'd be listening at levels that can damage your hearing.
I think you probably are aware that I knew this but I didn't want to confuse the OP
Why not simply tell him what he wanted to know?
Judging by his thanks I think I did.
I'm not being arguementative, I'm expressing the fact that you misinformed the OP. How do you know that the answer to his question would confuse him and if it did then you can simply take the time to explain it to him.
Your explanation is like telling someone who asks what a door is to go use the window.
Thanks. I never really understood what was meant by reference level until I read this. Just tried watching a film at 0db on my Denon AVR-X2000 with Q Acoustics speakers. Bloody Hell!!!! How can anyone watch a film at this level? Think my eardrums would explode after about 5 minutes
