In Reply to: DTS vs. DD: Shouldn't DTS sound better? posted by sjt78 on January 6, 2005 at 10:15:50:
My receiver is a brand new Yamaha RX-V1500 which is mid-priced. I imagine it is up to the challenge of decoding both DD and DTS fairly well. In the few DTS discs I've tried, the center channel sounded muffled compared to the DD. Maybe I need to boost the CC in DTS mode and see if I like it better. A 1-2.0 db boost shouldn't screw up with the overall sound, would it? Also, maybe I need to play around with the dynamic range function and put it on MAX? Any other suggestions? Thanks.

I have a Yamaha receiver as well, although much older, and experience the same thing on the center channel. Using a calibration disk and SPL meter helped me figure out that there was an almost 6db drop in volume for the center. The muffled sound you're hearing could be a combination of the decreased center volume in addition to more information on all the other channels (from DTS).Playing with the settings (6db boost to the center) helped greatly, although this is a pain to set every time I rent a DTS disk, so I normally default to DD.
That's good information to know. I got the receiver right before the holidays so I haven't had the chance to do any calibrating with the spl meter. Does your receiver have built in test tones? Mine does and I was thinking about using these to calibrate the front three channels. But if it is a brand-specific problem, it's not that difficult for me to up the db's on the CC on this receiver. I can do it by the remote. Thanks.

I think it does, but I used the DD and DTS calibration from the Home Essentials setup disk. This showed that I had the drop on DTS, but not on DD. I set the SPL to 70db, which is where I usually watch movies at, then turned the volume up until L/R were at that level, then matched the center.
