Hi Drifter--
Everyone's given you excellent advice. So I would try those. But I have had an experience that sounds similar, and I *know* it is broadcast related, not the sound system or setup.
Here is when I have an issue:
When I am watching digital cable, and I am feeding the receiver/processor the digital audio signal for 5.1 processing, some broadcasts are very screwed up. Specifically, the two most common issues I experience are:
1) The 5.1 mix is just terrible. For example, last year during a few football games, sometimes the announcers were mixed incredibly low, but the fans in the surrounds sounded like they were on my sofa! While not always sporting events, live events seem to be the most common times I experience this sort of mix issue.
2) Going from a "national" commercial to a local air spot. Suddenly the receiver is processing a locally produced commercial and it is clearly a very different mix, and all of a sudden everyone is jumping for the remote to turn down the volume because it has become unbearably loud *and* distorted.
Are those the kinds of things you're experiencing? Or is it more general and common? If the latter, the prior recommendations should really help. If it is similar to my experience, I've got no advice other than keep the remote handy!
Seriously, if anyone has any ideas on how to help with the kind of issue I'm referring to, please chime in!
Regards,
Rich
