7.1 channel surround

[jshannon]

This may be a dumb question, but I have a 7 channel surround system set up. My question is, if I am playing a 5 channel blu-ray disk, will only 5 speakers put out sound? My rear surround speakers do not put out any sound while playing movies. Is this just how it is, or am I doing something wrong?

If ur receiver is capable of matrixing than that works. If u have listening modes like PLIIX or NEO6 than ur good. Theres some other thx listening modes but im not sure what they are.

it will play whatever the movie is. if its 5.1 then it will be 5.1 UNLESS, you use a listening mode on your receiver to matrix the audio from 5.1 to 7.1

I have the Sony STR DG-720 set on PLIIX and it does a good job of matrixing 5.1 sources to 7.1. As was mentioned, if you haven't set the receiver to matrix then you will only hear what is recorded on the mix.

What happens if your playing truehd or dts hdma?

if you've got a 7.1 system and your playing a 5.1 movie then of course you shouldn't have any sound coming from your rear 2 speakers. try playing a 7.1 movie and see if you have sound then. in most cases on blu 7.1 is going to be DTHD or DTS HD MA rent or buy (unless you already have it like i do) sleeping beauty and play the dragon encounter there is incredible 7.1 sound usage in this segment, trust me!

I prefer playing the intended 5.1 track rather than matrixing with the receiver to a 7.1, but that's up to you..... but to answer your question, "YES" it's normal
