Logitech Z-5500's producing a really annoying popping sound

DarkShadow · 26 Feb 2006 at 13:09

As above, it has now been occurring since I bought them, I always had the impression that it'd go away but now it has started producing ever so slightly more frustating popping noises.

It has also started producing a humming sound if the speakers are turned on.

There is no interference, as everything is well placed.

I know some people here had the same issues, how did you resolve it? I'v gotten to a point when my headaches just can't handle the random popping throughout the day on a daily basis.

Its most likely electrical interfirence on the power line. This speaker set is unfortunatly very sensitive to it. A good power stripe that included emi protection does minimise it.

Ive had the same issue from day 1 with my logitechs as well. Im living in an apartment off campus and whenever my roommate turns on a light or tv in his room it causes my speakers to pop so its never a random thing.

Anyways I remember reading you can get one of those backup power supplies to clean up the signal and help maintain a consistent power current to the speakers.

After a quick google, I had read up on other people having these issues and so on.

I have very high end surge protectors. I used 2 of these *Belkin Gold Surge Protectors*

So that eliminates the need for clean power supply. Has anyone contacted Logitech regarding this issue?

Just parroting info here but I have heard that this can be caused by the EM field from the gigantic subwoofer, have you tried moving the sub further away from the sattelites?

I only brought my Z-5500 last saturday(3 days ago) and there doing this popping noise

..
Sounds a bit like the amp is turning off and on.

I do wonder how logitech speaker sets get THX certification when they pick up and amplify interference/LineNoise so easily :/
