I have heard this term for years, and never really thought much about what it really means. So, what exactly is "reference" level?
In a related (maybe?) question. I just upgraded my receiver to a Denon 2802. Unlike my old Sony STR-DE915, the Denon manual actually tells me what to calibrate my speakers to, so I picked up an SPL and got everything balanced at 75db/C/slow. But, when I adjust volume on the Denon, it is showing me everything as an offset in dB (starting at -55db, I believe).
Ok, so I assumed that if I balanced to 75db, that '0db' would get me back to 75db, but when I test the levels at the '0db' volume level, I'm actually getting about 94db output. Does this make sense? What does this volume setting dB value actually refer to? And, does this tie back to the "reference" level definition, or do Dolby Labs and dts have their own levels they consider "reference"?
