I've got my Pioneer VSX-921k and Diamond 10 Package ready to wire up when I finish work on Friday.

I was just thinking. I have my PS3 with Optical and HDMI output (for DTS) but Sky HD is only via HDMI. I realise that Sky HD can only output 5.1 sound via Optical however I won't be able to do this without getting the electrician back in as the HD box is in a different room.

Will the AV Receiver still be able to take advantage of surround sound via Dolby Pro Logic or something similar? I'll be really annoyed if Sky HD literally only sends a 2.0 signal vida HDMI.

Cheers

Is this right, that is utterly ridiculous!?
 
550w will be pretty much worse case. I'd expect it to use somwhere around 80-120w when idle.

prologic II is pretty good with any stereo source (except music, blurgh) so I'm sure it'll be fine :)
 
It's a Maximum of 550W, balls to the wall, all speakers blazing.

I think my Sony is rated at 450W, when attached to a power meter it's typically around 80W.

Sky only sends stereo via HDMI, however, Pro-Logic can upmix any stereo source, so you'll have pseudo surround sound :)
 
Thanks for the replies gents, really excited about setting up the kit now! :)

I also splashed out on the 10.CS centre speaker and cannot believe how enormous it is!

I am no expert but I seem to remember that Pro Logic works by filtering out sound which is 180 degree phase inverted and then sending it to the rear channels. Is this right? I remember when I used to make films as a kid I used this trick to create an unofficial Pro Logic sound track to go with my films :D
 
There are two approaches with ProLogic. Some programmes will have a dedicated Pro-Logic mix so there's no need for pseudo-anything. The information will be encoded in the stereo track and picked up by the amp to reproduce the centre and mono rear surround info.

Those programmes in stereo only can be "surround-ised" with Pro-Logic. It's not as effective but it'll do. :D
