Hello everyone I´m BladeDTS and i need some information, I'm new to AVS forum and pleased to make your acquaintance. My question is as follows I have a Pioneer VSX-520 which is 5.1 but if i tell the receiver that there are back surrounds i get DPLIIx and extra modes. However I do not have any way of adding the 2 other speakers (space, economical confrindgments) do I gain anything from running 7.1 modes on a 5.1 system? example DPLIIx Music with just five speakers. Any help will be most appreciated.

I'm not sure I understand. The VSX-520 receiver is a 5.1 receiver - you physically cannot connect another pair of speakers.

So when running a 7.1 source into it via HDMI, it will down-mix the rear surrounds into the "regular" or "side" surrounds to provide a 5.1 mix for the 5.1 set of speakers.

Since you are in the Surround Music Formats forum, I should mention, in case you are not aware, that SACDs and DVD-As (and most regular DVDs with DTS or DD) are all 5.1 mixes. The most common source of 7.1 material is BD movies - even most BD music disks are mixed in 5.1, I believe (though I am happy to be wrong).

I suppose the DPLIIx modes are engaged if you tell the receiver you have a 7.1 source to allow you to choose various downmix implementations (maybe there are some downmixes that mix some of the side-surround into the front channels...I dunno, just guessing).

Can you provide more info about what you are trying to do (i.e. you do indeed have 5.1 speakers, you have a BD or SACD player model x, etc), and what kind of source material (SACDs, DVDs, BDs) you are wanting to play?

Thank you. Yes I can clarify my amp has surrback pre-out to which I can connect another amp or active speakers making it 7.1. Nevertheless the question was do I gain any benefit from running 7.1 enconding in stereo music and movies on wothout adding the 2 extra speakers. You see I add them in the menu although there is nothing connected to the pre-outs.
