Ok... got fios installed. I am running an optical to my amp and a handful of sd channels are incredibly loud and distorted. I've tried using several optical/coax cables , different configs, no change...I called Verizon they said they send unfiltered signals and I need either a preamp or some filter...(using rca jacks the sound is normal...all other hundred plus channels heve excellent sd or 5.1 sound)...Is there some cheap filter that takes a optical/coax in and sends the signal out via optical /coax? If not what's my fix? Thanks a lot
FIOS doesn't know what they are talking about. The problem is with mixing by the studios/stations. The only way an receiver can help is by buying something like Denon's (really Audyssey's) dynamic volume that can clamp it down.
Google for "loud commercials" and you'll get a lot of hits.
