OK, here's fair warning: If you're not familiar with how dialnorm works on Dolby Digital soundtracks, you might as well skip this thread, 'cause it won't interest you.
I recently upgraded to digital cable and now have access to a wonderful array of alternate programming, including OAR-friendly services like Sundance, IFC and TCM. But I'm having a technical problem with TCM, and I'm trying to determine whether it's TCM's problem or that of the cable service (corporate cousin Time Warner Cable).
TWC's digital cable service sends a Dolby Digital soundtrack for every channel except the major networks. The most common format is, not surprisingly, DD 2.0 -- which is appropriate for many of the mono sources shown on TCM.
But I can barely hear it, even with the volume on my Lexicon turned to the max. I finally checked the technical readout on the TCM signal and was astonished to find a dialnorm setting of -31db. Yes, that minus thirty-one. Those of you familiar with previous dialnorm discussions in Software know that the default setting on the Dolby encoder is -4db, and that's what most DVDs use. Minus 31db is a much greater reduction in volume than anything I've never encountered before, even on DVDs from Columbia TriStar DVDs, which are known for their aggressive use of dialnorm. It has to be a mistake. There's no reason on earth for such a setting.
I would much appreciate it if anyone here who receives TCM with a DD signal could check the dialnorm setting and let me know what it is. When I start pursuing this, it's going to be a battle just to find a customer service person who even understands what DD is, let alone dialnorm. So before I start, I'd like to try to identify whether this is a TCM problem or a Time Warner Cable issue. Thanks in advance!
