Soi just set up my 7.1 with the extra speakers going into the front high area. I have a Marantz SR7007

Thought id test it out, got test signals. Great lets put a movie on.

I put Avengers in (thought this would be a great movie to check) and im getting zero sound out of the front high speakers. Anyone know why?

If the Marantz is selecting Dolby True HD, with a bluray disc, then no you will not get the height speakers to play. I believe you need to select something like Pro Logic IIZ. I had the same problem with my Onkyo 1007. It wouldn't play wides or height with a blu ray disc because I had selected Dolby True HD as the prefered sound field on blu ray. I could be wrong, but it wouldnt hurt to try changing the sound processing to see what happens. Oops! someone beat me to it.

Cant really give you advise one that one because the Onkyo doesnt offer it. Give them both a shot and see what you preffer. Glad you got your problem resolved. Now get off the forum and enjoy your new set up!

True HD + A-DSX (height)


is that any good? compared to the PLIIz
Listen to them both and decide which you prefer. Just so you know how they work: PLIIz extracts ambience from the surround channels to feed the height speakers; by comparison, DSX generates early reflections (that weren't in the soundtrack) to feed the heights.

I now have Dolby True HD + PLIIz set but would i be better just using True HD for a movie like Finding Nemo that does support 7.1 and not the PLIIz setting?
The list of movies with 7.1 channels are all 5.1 + 2 rears; none of those 7.1 soundtracks are 5.1 + 2 heights. The only way you'll get all 7 of your speakers to light up is to use PLIIz processing.

Could you elaborate on this please, i dont quite understand how it generates something that is not there....

Ever play with the reverb knob on a karaoke machine? That reverb wasn't in the recording (otherwise you wouldn't be able to adjust it).


Same basic concept, more sophisticated processing, and you can simulate a few of the early reflections from a concert hall or jazz club. And that's essentially what Yamaha DSP and Audyssey DSX do: room simulation (give you the impression of being in a larger space).


You can hear it for yourself without extra speakers IF your receiver has any of those Hall or Stadium or Club modes.
