I'm constantly changing my speaker volume levels, mostly the center and surrounds to get a particular movie to sound better. Sometimes it's low dialogue, or surround efx that I know are there, but I can't hear. I take it there is some kind of standard level the audio guys on the film are working to when they do a final mixdown and when the DVD is made, but every film seems to have different levels. Maybe they should put bars and tone on the DVD before the film starts. I have a B&K 4090 which was set up using Video Essentials and a sound pressure meter. My speakers are Paradigms, all matched. Anybody elese find themselves adjusting individual speaker volume from film to film?
