my logitech Z-5500 system is picking up a radio frequency and I can hear it talking all the time.. It is really faint but it does not change with a volume increase or decrease, it is there all the time. Is there any way to fix this? I haven't had this problem in any other location. Thanks!
 
You could buy a small magnetic choke to see if that solves the problem. Other than that I'm not aware of any sure fire ways to kill RF bleed. Copper wire makes a good antenna.

We need to know if it's from the internal wiring or if a cable is picking this up.
Does the RFI occur even with the system not being connected to the computer?
If not, then you might try a better cable.
If it's being detected within the unit, a brief touch up job on contacts with a soldering iron or re seating of header connections may fix this.
Physical shock can cause cold solder joints, which can act as a detecting diode.
Think crystal radio construction 101

Thanks. I will have to try a few things and narrow it down.
 
the set i had did the same thing, ended up just replacing them. i tried a choke which didn't fix anything, tried moving them around, surge protectors, other stuff. if you look on the intrawebnets you'll find it's a common problem with that set of speakers.

It's not really a big deal, the faint noise goes away when you turn it off and you can't hear it when you listen so i'll just turn the system off when I go to bed
 
Hey yoyo, do you know of a good newbies guid to correctly setting up a speaker system, and choosing the right options in your sound card options?

And what materials do you suggest to build a cheap easy speaker stand?

Sorry, I just know your the sound guru, and I had to ask.

Lots of other people know as much or more than me about all this sort of stuff but I tend to get around a bit more for these subjects 😛

Setting up as in placement and such?
http://www.dolby.com/consumer/home_entertainment/roomlayout.html <-- read the tips at the bottom too
http://www.polkaudio.com/education/advice.php <-- this is a bit dated and is a little pro-polk as could be expected, but has a lot of info

Those are both related to HT oriented systems. Is that what you're setting up? What are you using?

For your soundcard, it's going to depend on what you have, how you're connecting, and what you're connecting to.
If you're connecting to a receiver, a card that encodes DD/DTS makes things a lot easier.

I'm not sure exactly which area of AVSforum would be the best bet to look for DIY stands, but this might be a place to start looking for ideas

Im using THIS 7.1 speaker system, hooked up to an Audigy 2 ZS Platinum. Right now, im only using 5.1 though. Its hooked up through the green, black, orange (analog?) wires, so its not digital. I know its not the wisest speaker purchase (now) but its what I got.

Im using CMSS 2 right now, which sounds pretty good. I was planning on buying some thin PVC pipe at Home Depot, and setting up some crappy stands. Once I get the stands, I was planning on hooking up the other 2 speakers.

Thanks for the links, I really wasnt sure if I should angle them toward me, or just put them forward. Ill see what I can do with my meager setup.

With that set, pretty much the best thing you could do to calibrate it once you have things set up is to adjust the channel levels of each speaker through the soundcard to get them all equal volume at the listening position.

If you wanted to get fancy, you could try to even out the response with the equalizer, but that would require getting additional equipment to do it right and I don't know if it would be worth it vs. saving up for a physically better system eventually.

For music most of the time it's a good idea to just leave it in stereo and not apply any fake surround effects like CMSS and such. This is totally personal preference though. Don't feel like you have to use all your speakers all the time just because you have them. Sometimes less is more.

For angling them, it's kind of up to you want you want to do. For example, I'm using dipole speakers for my surrounds and normal direct radiating speakers for my rears. You could play around with aiming the surrounds and rears in different ways to see what you like best. For gaming and multichannel music though, keeping everything pointed in your direction is probably a good idea.

Computer speakers are often very directional so keeping them aimed at you will probably yield good results.

Oh and I haven't used a creative card in quite a while so I'm not too familiar with CMSS settings vs. other options. Can you do DD/DTS from your DVD software instead of CMSS? I'm not sure how the options work on the creative software and how CMSS settings relate to audio on DVDs.

Some of the subwoofer placement ideas on those sites might not be the best idea for a computer setup. Due to limitations of the lower frequencies the small satellites computer speakers use, computer "subwoofers" often play much higher frequencies than a typical HT sub. Because of this, you'll probably be able to locate the sounds coming from the subwoofer wherever it is the room. Keeping it close to centered in the front of your listening area might be a good spot to try it.
