My setup
Thanks for your replies.
My current setup is:
A brand new Panasonic HD Plasma TV (sweet!), although I had the problem with my old RCA set as well. I also had HD Cable set up just two weeks ago.
My receiver is an RCA 600W Home Theatre.
My DVD/VCR is a Toshiba.
This sound issue has been this way since I first hooked up the Home Theatre setup a couple years ago. I just never bothered to straighten it out. I assume you are correct in that I must level the speaker channels. But which channel is "booming" through?? I'd like to resolve this without buying additional equipment. I can't believe it's not a typical problem that everyone has. My set up shouldn't be unique. Doesn't anyone else have this issue?... and how did you resolve it? When I go through the normal channel testing (through the receiver), I don't notice any unusual sound level in any of the channels.
There's got to be a simple solution, and as suggested, maybe I just need to play with the channel levels to level out the sound. But it's crazy to have to sit with the remote to adjust the sound everytime a new scene happens.
