Need Some Advice on Audio Setup

post #1 of 7
Thread Starter 
Okay so I may be out of luck here because I'm not the most techy person in the world and may just have the wrong equipment. So really, I just want to know what I can do to get the most out of what I have without spending more money asides from new cables etc;

This is what I have:

Sharp XR 10X Projector - Capable of 1080i HD - uses 2 VGA slots which double as component inputs via an adapter (no HDMI)

Pioneer 7.1-Channel XM Ready HDMI Receiver
http://www.bestbuy.ca/catalog/prodde...69&catid=20313

Sony PS3

Right now I am only using composite cables for the audio and I know that's not getting me anything fantastic. I am under the impression that I can't get 7.1 surround without HDMI, is that right? If so, what do I do. I know that I can convert the HDMI signal to component with a 200 dollar adapter, but I don't really want to spend that much because it's not that important to me.

What is my best option without spending a ton of cash to get some decent surround sound out of this setup? Would an optical sound connection probably be my best bet? Any suggestions as to what I can do would be hugely appreciated.

Oh and also - I keep hearing about lossless audio etc; when reading forums on blu ray - now I'm pretty sure I probably didn't spend enough money on the reciever to get that kind of feature (and also I've heard that the PS3 isn't even capable of it anyway) but what is the best type of surround sound setting to use when watching a blu ray with the reciever I have and the setup I will hopefully have after all of this is over. I'm hoping to keep my spending to under $100 - but I am always open to hear what I can do with more. Thanks a ton.

Here's the back of my reciever


And the back of the projector if it's of any importance

7.1 is available with any 7.1 receiver with a DPL IIx or Neo:6 decoder. It's also available with a 7.1 receiver with Dolby EX or DTS ES decoders when playing an EX or ES DVD. You need to use an optical or COAX S/PDIF connection or an HDMI connection (not all HDMI equipped receivers support the proper features, but yours probably does.)

What HDMI gives you is lossless audio from the PS3 in the form of TrueHD (DTS-HD Master Audio is not supported.) The PS3 decodes the TrueHD soundtrack and sends the audio via multi-channel PCM (MPCM.)

So you would suggest optical. The only thing I don't understand is that when I go into the PS3 audio settings and select Optical - it only gives me up to 5.1 surround as an option. I need to go into HDMI to select 7.1 what's the deal there? Anyway, optical seems to make the most sense for my set up. How much do you think that cable should cost? 10, 20, 30?

A Digital Audio Cable shouldn't cost much.. under 20$ depending on the length..

Look on Monoprice.com for your cables they seem to have the best prices anywhere.

I am not 100% sure what you are asking, and don't own a PS3.

I will make some a guess here. If you can select 7.1 in the PS3, that's probably telling the PS3 that your AVR can support 7.1 MPCM. That would be helpful for games or movies which support 7.1 channels, because the PS3 could then properly redirect the rear surround channel(s) to the proper 5.1 channels (when 7.1 is off.)

For optical, a 6.1 DVD soundtrack should simply be sent on to the receiver. For a 6.1 or 7.1 game, if there is such a thing, I can't say, but I would not expect the PS3 to be able to do anything but send it as 5.1 Dolby Digital (sending 6.1 would require it to encode to Dolby EX which seems unlikely.) For 6.1/7.1 Blu-ray movies, which don't exist AFAIK, I really have no clue, but would once again expect it to send 5.1 Dolby Digital, perhaps sending the rear surround channels to the surround channels.

If you want 7.1 from the PS3 you need to use an HDMI cable. It will not send 7.1 through optical.
