Re: Room Calibration for Film and TV Post
Dan,
AFAIK, you use 82 db SPL for a mono surround track (i.e. Dolby Stereo LCRS). In that case, when the channels sum up acoustically, 82+82=85, but only for theatrical mixes. LCRS mixes for TV and DVD use 85 dB for the surrounds. 85 is also used for 5.1 (discrete surround) mixes, theatrical or otherwise.
At least, that's what I think it is. There are a lot of folks on this board who know more than I, so, as always, take the info with a grain of salt and double-check it.
Hope this helps.
