iPod Docks

[Demiurg0]

Hi all,

I've searching for this topic over the forum but i didn't find anything.

I have a Pure-Fi Elite speaker system since a month ago and yesterday they suddenly started having some kind of strange noise on the front speakers.

Some notes:

- The noise seems to be a static noise (white gaussian noise), IMO it comes from the power source

- The noise is present even when the speaker system is turned off (with or without any iPod connected)

- The noise is volume-variable, it has not always the same volume

- There is a strange "zap" when i change the music source when the speakers are on. I think this "zap" has appeared when i started hearing the noise, so maybe they are related

- The noise seems to be off (no noise) when I pause the music (pause on iPod source, pause on FM source, pause on AUX source)

- The noise seems to be off (no noise) when I unplug the power source of the speaker system and i plug it again. This situation will go on until the first time I switch on the speaker system, and then the noise will appear again

- I have already reseted the speaker system to factory defaults, having no results

 At the end, i think the problem is the power source, like if it has a static charge that is messing everything. I can't understand why Logitech does not place a "ground pin" in the power source of this kind of electronic devicesto avoid this things.

Any clues? I think im going to return them to the shop

Thanks in advance
