I've had this Logitech Z-2200 speaker system for about 2 months now, and I've been very content with it (it's a 2.1 desktop speaker system with a massive sub; great speakers, I highly recommend them). However, lately I've been noticing that there's a lot of...trash noise in the background. It's not really static; sometimes it sounds like bass or just something thumping around. Anyway, it's annoying background sound, and it happens even when I don't have any music running. I've narrowed the problem down to the left speaker, but I have no idea what's causing it. I was wondering if any of y'all might know anything before I go talk to the nice people over at Logitech. Any help would be appreciated.
I'd go to the nice people at Logitech first, but... you can get a hum in a speaker if the speaker wire runs parallel to an electrical wire for any reasonable distance (aka, the 60Hz buzz). Outside of that I'm not sure...
What DoD said sounds most likely to be what's happening.... And I have the same set of speakers, I freakin' love them, especially for the price I paid!
I got mine for $60 after some sweet rebates, so I love them too... DoD, thanks for the advice, I checked it out. The sound isn't a constant hum or anything, just sporadic bumps. I checked for electrical wires and didn't find any that really ran parallel for more than, say an inch and a half. I e-mailed the Logitech dudes and they should get back at me sometime within the next week. But thanks for all the help!
It could be one of your cable connections -- dust or something -- have you tried unplugging and then re-plugging every cable? Also, sometimes you have problems with random things that have feedback. Next time it happens, try to identify something that's running at that time that wasn't before. I have a fan that when I turn it on, it causes the speakers to hum.
First, you check to see if it's the source or the speakers. You do that by unplugging it from your computer (I assume that's what they're playing from right now) and plug it into a portable CD player or any other source that the plug will fit. If you have the identical problem, it's in the speaker system. Then you check to see if it's specific to the left speaker, or the connector where the left speaker plugs in. If you can, reverse where the left and right speakers plug in. Some 'multimedia' speakers won't allow you to do that. If the problem switches to the other speaker then the problem is in the main unit. It's a good idea to unplug and clean and replug every connection. If a connection is tenuous, the vibration of the sub can shake it enough to put some scratch into the sound.
