I’m not quite sure how to phrase this question.

I’ve been reading a little about people calibrating their sound systems. People keep referring to the fact that they have their mains calibrated to 10db less then their subs or it’s reading 80db on the SP meter.

I just took delivery of my HK 635. This is the first AV receiver that I’ve owned that reads a negative number on the display with regards to volume levels. I guess I assumed that this number was based on some kind DB scale. But after reading what people have posted I’m not so sure.

I have the Avia disk and the HK has an EzSet and EZQ. It directs you to set you volume level to –35db and then it performs a calibration of my speakers accounting for room acoustics and volume levels.

I’m sure this is just a matter of a particular scale but how do some of you set it up to 80db when my receiver is cranked at –10. I’m confused.

Don’t get me started on reference levels. I don’t think my walls can handle 105

Thanks in advance for the lesson.
