A surround sound question from a guy who knows jack about surround sound

I've got both a Wii that outputs in Dolby Pro Logic II, and a PS3 that outputs in Dolby Digital or Dolby TrueHD. If I buy a surround sound system, would it be compatible with both of them, or just one or the other?

Re: A surround sound question from a guy who knows jack about surround sound

Your Wii puts out an analog signal on those red and white RCA connectors. Basically, it puts out two channels, then your receiver turns it into surround. As far as I know, every surround system ever made except some that don't take external inputs at all will handle that. Anything vaguely recent should be able to process it as Pro Logic II as well. (Early system only did Pro Logic I).

Your PS3 can put out Pro Logic II as well, but you are better off using digital audio because it can natively put out surround channels instead of faking it. You can do Dolby Digital and DTS with the optical connector, but to do Dolby TrueHD (or any of the DTS-HD formats), you need to use HDMI. These formats are different ways of compressing the audio, kind of like mp3, but higher quality. Your PS3 can actually decompress the signal itself, so your receiver only needs to take HDMI, not decode these formats. (The optical doesn't have enough bandwidth for uncompressed surround sound.) I actually recommend setting your PS3 to decode the audio itself because otherwise stuff like sound effects on a Blu-ray menu won't work because it can't send the compressed movie audio and the menu audio at the same time. It has to decompress to mix them.

Thanks!

So I will be able to plug both consoles in to the same surround sound system then?

If you get one with the right inputs (which most modern ones should have), yes. Most receivers prominently list their inputs and the formats they handle.
