I always thought this was cut and dry, and easy to do. However, after updating my Rotel it seems very loud when I listen to movies at 75dB. Here's how I calibrate...please tell me if I'm wrong. I take the AVIA DVD, and run a test tone on my LF speaker. I turn up the volume on the Rotel until it reads 75dB on the meter, C weighting, slow... Then, I make note of the volume setting for future reference. I then make sure all other speakers/sub match that decibel reading as well until they're all equal. I only go to 75dB because 85 seems way too loud. However, now even 75dB seems too loud using AVIA. I understand that AVIA intends users to calibrate to 85dB. Does this mean that I should calibrate to 85dB using Avia, and then simply turn the volume down until I reach 75dB and remember the volume setting for movies etc? I've run several searches on this forum and can't seem to find a concensus... Thanks!
