Converting 5.1 to 7.1 Using Dolby PLIIx

post #1 of 3
Thread Starter 
I set up my system a few days ago and have been watching everything, mostly 5.1 movies, using a Dolby PLIIx setting. I found this interesting article .... http://www.hometheaterhifi.com/volume_11_1/feature-prologic-iix-3-2004.html

I wondered if this is the appropriate setting. The center channel seams a little too soft on some movies, like Terminator 2. Just curious for some input on this setting and if there is anything I can/should do about the center channel. (I haven't tweaked the Audyssey settings.)

Thanks!

creating back surrounds with PLIIx (or anything really) does NOTHING to the center channel. These back surround matrix schemes just operate on the two surround channels and use the data in those two channels to extra the additional back surround channels. The front 3.1 channels are untouched.

in general PLIIx is the preferred setting for this function.

if you are having issues with dialogue intelligibility it is a totally separate issue. What receiver do you have? Are you using Dynamic EQ and/or Dynamic Volume? Is your center channel well-placed with the tweeter aimed at ear level?

My center chanel is under the display and angled slightly up (tried to aim at ear level) and there is nothing between me and the center channel... so, I don't think that's the problem. I have a Denon 3312ci set up with Audyssey Auto Setup. I did not change the settings using Dynamic EQ or Dynamic Volume. I read the section in the Manual, but have not tried to make any adjustment. The center channel sounds fine when listening to TV shows.
