Connecting 5.1 Computer Speakers to Computer via a Receiver

[hador7]

Hi guys,

I'm looking to buy the Logitech x-540 5.1 Speaker System and I want to know, is there a way to hook these speakers up to my receiver? I want to be able to use these speakers to output sound from different inputs, whether it be the computer, my dvd player, or cable tv. For those of you who don't own this, here is a pic of the back of the subwoofer:

The lime green, black, and orange mini 3.5mm jacks connect the subwoofer to the computer. The other 5 are RCA jacks that connect to each individual speaker.


--------------------------------------------------------

If this setup is not possible, then is it possible to output 5.1 channels from my computer to the receiver (so that I can use my stereo speakers)?

I know it's possible to do 2 channels by using a 3.5mm mini-RCA cable, but I'm not sure whether it's possible to do a 5.1 channel setup or even a 2.1 channel for that matter.


Thanks in advance for the help

I'm not sure how you mean... if you want to use the receiver to provide amplification for the Logitech speakers, you can just cut the RCA jacks off the speakers & plug them in to your receiver, but you won't be able to rig the sub to your receiver (and therefore not recommended). If you just want to use the receiver as a means of switching inputs, you can; all you need to do is connect it to the preouts on the back of your receiver. Ideally, the receiver will have 6-channel preouts so that you can get true surround this way, but if you only have two channel preouts (sometimes labelled as tape rec or VCR REC), then you'll have to use the matrix mode to get a surround effect.

Yeah, all you need is to have a 6 channel input on the receiver & three 3.5mm to RCA cables. If not, you're out of luck for anything more than stereo.

Thanks Kwirky for confirming what I was thinking.

If I were to cut the RCA ends off the computer speaker cables, and plug it into the receiver, will there be any issue because the speakers are already amped? Or has that got to do with the subwoofer?

Sorry if the question is unclear, I got that response from another poster in another forum where I posted this message and I am not too sure what it means. This is my first time setting up a speaker system through a receiver and I want to make sure I don't blow out anything.

The amplifier is in the subwoofer, so if you bypass that by plugging the speakers directly in to the receiver, you won't fry anything. Still, that's not to say I'd recommend it - the speakers are made to take the power of a 7 watt amplifier & your receiver will have a lot more power than that. The amp in the subwoofer probably also has a high-pass filter to stop the low frequencies from going to the satellites & redirecting them to the subwoofer; if you send these low frequencies at high power to the Logitech satellites, they will at least distort, and and worst rip themselves apart.

You can still use the receiver, but I would use the 6-ch preout on it & connect that to the Logitech via 3 RCA - 3.5mm cables. That way, you're not likely to ruin anything, and it won't void your warranty (which I'm sure would be the case if you cut the connectors off the speakers.

You can try one of these:

LOGITECH 5.1 Game Adapter (http://www.memoryexpress.com/Products/PID-MX9842(ME).aspx)

Basically, it takes up some room but you can still make it work. Connect your R/W rca audio out from your receiver to this adapter and then connect the 3 3.5mm plugs to the adapter and finally to your logitech sub. So basically, you are only using the receiver as a switcher. But the problem is the decoding, I don't know if the signal from the receiver will be properly split by the logitech amp.

you could fry your amp and or your logitech speakers if the amp has a different ohm rating other than the speakers. Speakers are not just speakers they are all not built the same......... some of these sets have 3ohm, 4ohm, 8ohm, 16ohm ect ect I'd check to make sure they are compatible with your amp before I cut anything. And to add to this your amp could kill these speakers if you send to much power to them, they are rated to the sub/amp it came with not a stand alone amp ...................all the numbers can and probably are different.

Could Logitech X-540 5.1 Speaker System connect to Samsung TV LCD? It would get damage?

Please let me know
Thanks
