Intelligability Problem

oops...to answer jeffreybehr... 5 channel NHT speakers all.

Do you have your TV muted? I used to run the HDMI direct to my TV and the sound to my pre/pro. If I forgot to mute my TV the timing in the sound from my TV did not match that coming from my HT system and it made it very difficult to understand. While you wrote that only the video is being sent via the HDMI to the TV, I would double check this. Since you indicate that this only happens with videos (vs. music only), it may be the cause.

Outside of this, it would seem it would be a set-up issue. If I am correct, you have run the full set-up, speaker placement/distances, etc. . . from the DVD player and during set-up the test signals all worked well?

I just keep going back in my mind to the dual outputs using the HDMI and the analog 5.1 channel output. Since it is not your HT receiver that is decoding anything (ie. based on the analog input approach and assuming you haven't programmed the Denon to do any changes to the analog signal).

I don't think my DVD player (Oppo) allows me to restrict the HDMI output to just video, but I may be mistaken.

As other have suggested I would check:

1) The set-up parameters of the center channel in the Denon

2) Use a different input/channel of the Denon for the center to see if it a problem within the Denon specific to the center input you are using (e.g. bad amp channel)

3) If possible substitute a satellite speaker for the center speaker to see if the problem is the speaker itself

4) Also play music through all channels as another way to check the center speaker

5) Turn off the center channel in the panasonic so the dialogue is handled by the front L and R speakers

This all should help pinpoint the problem.

Thanks for the suggestions. When I put my ear to the center channel, it is working...its just the QUALITY (bad) of that speaker is not good. I will connect the output wires that go into the center channel to one of the towers to see if it is indeed a defective center channel speaker. I'll get back. Thanks again. By the way...there is a definite page for HDMI distribution on my BD-55 Panasonic... HDMI Video, HDMI Audio, Both. I have it set only to Video. The TV sound is set to "off" on the Sony.

Lots of DVDs and Blue Rays are mixed with the dialogue rather low relative to all other sounds. Presumably, the viewer is expected to raise the volume until the dialog can be clearly heard. Unfortunately, loud effects are then LOUD! I think that's the idea - recreate the in-cinema experience, but it can create the issue that you're describing. Particularly since you don't have an issue with TV content, which does not feature this type of audio mix.

My fix is to manually raise the level of the center channel while leaving all other audio channels at their "default" level.

Just one more ideafor you to consider.
