I would for the sake of simplicity make sure that you have a set of satellites and a matching centre/sub woofer speaker. Two reasons really, one the hookup will be perfect, secondly the frequency responses of the satellites and the sub will be matched correctly at the same crossover frequency. As you have it now the sound may be a little sparse or over boosted. Your card has two stereo mini jack outputs for front and rear speaker pairs, hook yours up to the one marked front. In a 5:1 setup you would have one more pair to hook up. The C/sub will be a mono minijack connection. SP/DIF is the Sony/Phillips digital interface and is most probably of coaxial type (althouth it could be optical on some models) locked to 48KHz if you need to connect a digital source. If you were determined or had to keep the Logitec speakers it should (somewhere in Glasgow) be possible to obtain a phono to minijack convertor with which you could connect your sub directly to the soundcard even though I suspect this was never intended as it should have been sold you. Many 2:1 speaker packages assume you have only a basic stereo out on the sound card and therefore you need to cascade either from the satellites to the sub or the other way around to get signal to all three speakers. The type of people in PC World generally know little more than how to shift a box out the door with your money having left its wallet. Their PC health checks are somewhat dodgy since they more or less involve wiping a machine and starting again. Regards.

Thanks for responding to my enquiry. Having trouble though getting my non-technical mind around what you are saying. hahaha. You mention the Sub. Is this the larger centre speaker? if so, there is a line from the powered satellite to this centre speaker; another to the other satellite and a third with a phono socket at the end, which I presumed, plugged into the Soundblaster. The Soundblaster has a USB to my computer. The Soundblaster has a number of sockets on the back and these are as follows: C/sub Rear Front Line in Spdif out Din Usb I am hoping that PC World will replace my Logitech speakers and exchange these with a Creative system. Am I correct in thinking then, that the Creative system, will all have individual miniplugs to fit each of these sockets, and that the USB will power them? Thanks. Best wishes.

It is most usual that either the powered satellite feeds the sub or the other way around rather than taking another feed directly off of the soundcard with 2:1 sound systems. The SP/DIF will be no good for this. Regards.

I have just purchased a set of Logitech speakers, which come with an additional central speaker. I have also purchased Creative Soundblaster 24 bit external soundcard. Audrey from this list kindly assisted in setting up the soundcard in order that I could retain my existing speakers for jaws. The sound card seems to be working for I can listen via headphones plugged into the front of it. However, I think I was sold an incompatible system from PC World. I've been on the phone to them for over an hour and all they can suggest is that I travel into Glasgow and take the speakers with me. It's over 2 hours for me to get in there on public transport. I thin the system is incompatible because the plug from the speaker system that plugs into the sound card is a phono plug and not a minijack. Although the soundcard does have a phono socket called Spdif out and the phono plug fits into this, I get no sound at all coming through the speakers. Can anyone shine some light on this problem please as I'd hate to go into Glasgow for nothing. Best wishes.
