Planned Home Theatre 5.1 Setup

[Tomm]

Hey,

As some of you may know a couple of months ago I purchased a 1080p projector. Since headphones is not exactly the best options for movies (and your limited to one person or two people with a splitter watching) i've decided to invest in a sound system.

Heres my current plan:

I've decided to spent my budget on quality speakers rather than attempting to include a subwoofer in the budget (Ill get one a bit later on) especially considering I need to splash out on an ATI 5xxx series for the audio bitstream over HDMI support.

The floor standing speakers are my front l+r speakers and the bookshelf ones are for the surround - center being center obviously :P

There wouldn't even be room in my house for this. Post pics when you get it all set up :D.

It sounds like you're using a computer? If so, drop the idea of audio over HDMI and get yourself a sound card in there with a digital optical ouitput. Much better alternative.

Also, you don't need a 5xxx series for it, the 4850, 4870 and 4890 can do it also as far as I'm aware. By far your best bet is a souncard in there with digital optical out though.

I know some people sware by Onkyo recievers, but I don't really know anything about recievers. Sony are gererally good too though.

I see you've posted on AVForums, which is your best bet for acvice on the speakers and reciever though. I'd take the plunge and get a subwoofer now though.

S/PDIF optical can't carry dolby truehd or dts master audio streams due to bandwidth limitations. Also if I wanted to do the processing of the audio on the PC for some reason I can't use 5ch or 7ch LPCM (at higher sample rates at least) as again there is not enough bandwidth with optical.

Also i'm not 100% sure but I think only the 5xxx series supports dolby truehd and dts master audio bitstreams.

Quote from Wikipedia:


A common use for the S/PDIF interface is to carry compressed digital audio as defined by the standard IEC 61937. This mode is used to connect the output of a DVD player to a home theater receiver that supports Dolby Digital or DTS surround sound. Another common use is to carry uncompressed digital audio from a CD player to a receiver. This specification also allows for the coupling of personal computer digital sound (if equipped) via optical or coax to Dolby or DTS capable receivers.

Edit: I didn't realise there was a difference with master stream. Ignore that.

Second Edit: Yes, it seems like you need an ATi 57xx or 58xx for the truehd and DTS master.

Yeah the master audio and truehd streams are 5 or 7 channels of complete lossless audio. Same with LCPM - tis uncompressed audio.
