Speakers

[Noics]

Hi

I recently bought the X-530 5.1 Surround sound speaker system and I've only had them for about a week now, but when I turn the volume all the way down to 0 on the right front speaker, it makes all of the speakers make this buzzing/humming sound but it goes away if you turn up the volume dial on the speaker, but it contiunes to do this even when the computer is turned off, i've check everything in my sound options on the computer and can't find anything and i've also plugged the bassbox into an actual wallsocket rather than in the extenstion cable

Any ideas?

Would be greatly appreicated cause I really like these speakers! =)

Thanks.

I bought the same speakers today. They worked perfectly for the first hour, then the buzzing started..... If I unplug the rear speakers, the buzzing stops. They buzz with the PC turned off, so it has to be some kind of interference. Are there such things as speaker connection filters? I wonder if I'm picking up a mains frequency buzz from somewhere? Hope someone helps us!!!!

Update - my PC system has been turned off all day (including speakers). Just in from work, no buzzing so far. I emailed Logitech technical support, and didn't receive anything by the way of useful help that I haven't tried already (except for "plug them into a power supply in a different building" for goodness sake). When/if the buzzing reappears, I'll find out if anything else in the house has been switched on which may cause the buzzing. The subwoofer is producing a very quiet buzzing sound - obviously the mains transformer - if you put your ear to it, you can hear it quite clearly. But it's not producing a signal which can be heard through the speakers. If it starts to buzz again, back to the shop they're going.

Hi,

I have a set of these speakers in my office. I do not leave them on all day, only when I am using them. The nature of amplifiers is to amplify. If there is no signal coming into them from a source such as a computer or MP3 player they will amplify the noise of the electrical circuit they are composed of.

Thanks for the reply, Mike. Not sure I believe your reply though. I've been playing guitar for 30 years, and I've never had an amplifier which buzzes louder with the volume turned down to 0. Why would the buzzing stop when the rear right speaker is unplugged? I really don't want to take the back off whilst under warranty, but I'm guessing the wiring from the top (rear right) connector is too near the transformer in the amplfier, and there is an inductance current produced in the top audio connector circuit. No other speakers I have ever owned have done this (including other Logitech ones, which I have found to be excellent, that's why I bought these). If they are buzzing loudly with no audio signal going to them, and the volume knob turned to 0, then they are obviously faulty in my humble opinion. Also, why are there pages of relevant results when I do a Google search for "x-530 buzzing"? If it's a design fault, then why are they not being recalled? Please take this reply in the spirit it is meant - I'm not "having a go" at anyone, just disappointed that the £55 I spent on these as a birthday present to myself is going to be lost .....

Another update. The shop where I bought them (CCL Computers) refused to replace them. They "tested" them, and returned them saying "no fault found". This isn't unusual for them - their prices might be cheap, but it shows if you ever need customer support. I received a new set of speakers from Logitech themselves - they have a very helpful and polite customer service. The new speakers are incredible - they sounded a little odd at first - but it's just because these are working correctly, and I wasn't getting anywhere near this sound quality out of the old ones!! A bit of tweaking with the equaliser, and now the sound quality is amazing! Thank you, Logitech!

Hi Mike,

I ready your reply to another post, and you seem pretty familiar with this system. I just bought it tonight, or last night, lol! I am curious how I should place the rear speakers?? They state to place them behind me, and there is nothing behind me but air. The wall behind me is a good 8 feet away. Also, any way to keep the wires from being "so" exposed"???

Any help would be greatly appreciated!!!

Thanks,

Rhonda

Hi,

From what I have read, placement of the rear speakers should be around ear height and about equidistant from the fronts. The sub, for the LFE channel, does not have to be in front of you and mostly I have seen it placed to one side and close to a wall. For music, I don't think it matters either.

There is lots of good info on where to place speakers at wikipedia and at Dolby's web site.

I guess some kind of stand would be needed.

The wires (always an issue!), you could run them under the floor, or along the walls... i guess it would depend on your room environment.

I tryed turning off my external hard drives and the buzzing was gone!

all the mucking around i have been doing searching forums etc 

anything with a spinning motor causes the interference.

just move your external hard drives away from pc or get a server in another room and connect to your externals through lan.
