can anyone think of any reasons why getting an external 5.1 amplifier, with full size speakers, would not work with an xfi, also would it be better to use a coaxial out or the analogue especially as the main use will be gaming

cheers
 
i understood that you'll only get digital pass through ie no game sounds, could be wrong though
 
The digital output would only be in stereo in games. You'd only get surround sound by passing DD/DTS straight from a DVD.

If your amp has a multichannel analogue input, you'd connect it up just as you'd connect up any other analogue speakers. This means that the card is doing any processing, and your amp is just amplifying the signal.
 
ok guys, jsut got the amp, its a cambridge audio Azur 540r and it has all the in and outs anyone could ever need :D

ive tried playing battlefield 2 with both analogue and digital, via toslink out on front panel of XFi, as far as i can tell the toslink has better quality, however when playing around in the settings for the xfi it has DTS out and Dolby Digital out, which of these is better? and how do i disable one, or can they both run at the same time without interefering, as the only options i see are setting it to an external decoder or the built in one, as the amp has its own DD and DTS decoders, surely both the amp and the Xfi will both be decoding :confused:

sorry for the millions of questions but this one has me really stumped :(
 
No games afaik produce DD or DTS sound. If you're playing games over digital, you won't be getting true surround sound, only the amp's upmixed version.
 
If you have a cdp with digital in or external dac, couldn;t you pipe the sound via that way?

Although that mean the you would get the cdp/dac decoding it wouldn't you?

Or could you pipe the xfi sound to a 5.1/7.1 av amp using digital connection, would that work as well?
 
The problem though is that the X-Fi doesn't encode DD or DTS on the fly, so in games it will only ever output stereo through a digital connection. Doesn't matter what you do to the signal after that, it's still just stereo. The only solution is three stereo 3.5mm to RCA phono cables and using analogue.
