Very good, Chet. In calibrating manually(I'd suggest using auto-calibration when available)most{all?)receivers put out a test tone that's 30dB below the 105dB maximum "reference"level that movie soundtracks are supposed to be recorded at. So, if that tone measures 75dB at a convenient reference point(often 0 on the scale, but not necessarily)then the setup is properly calibrated to play the sound at the reference level when the volume is set to 0 or whatever the reference point for the calibration was. For home use the reference level is generally considered too high for a steady diet and a setting 10 or more dB lower is common, resulting in a maximum level on peaks of no more than 95dB. The low frequency effects(LFE)occasionally present during movies are in a separate channel usually assigned to the sub, if available, and have a maximum level 10dB higher than the regular soundtrack.

It can also be noted that music recordings have no standard "reference" level and can vary widely in the volume setting required for a given loudness level.
