Hi all,
So, I moved to Toronto recently, and met a friend I haven't seen in a while. Long story short, she brought some speakers over from Austria. They have a problem.

1. Logitech x210 (shitty, I know. Not mine)
2. They run off 230v 50 Hz. Toronto is 110v idk Hz. A simple socket adapter is what she uses (wtf?)
3. The problem is that they fuzz really badly every 10 seconds. One turns them on, they fuzz. ten seconds later, if still on, they fuzz. It lasts about a second, is quite bad. They do this regardless of whether the input cord is plugged, music playing, etc...

My hypothesis is that they are not meant to be run on 110v. It seems pretty obvious, right? Well, here's what confuses me: they don't fuzz permanently. Unless the AC runs at 0.1 Hz (which I can confirm is not the case), they should fuzz permanently, right?

So, I put that hypothesis on hold. I open the thing up (woofer encloure). No sign of trouble, so wire connection issues are out.

Next, I bypass the woofer entirely and plug the satellites into my output jack raw. I know it's bad, but what's to lose? Man, terrible sound quality. They work. Wierd...

Any opinions? I' still sicking with the power supply incompatibility hypothesis.

Fuse set properly?

It could be some capacitors are not charging/discharging quite properly because of the voltage. That could very well make the fuzz every 10 seconds.

Yeah, just opened up the woofer control module (what crappy workmanship, only rubber glue holding everything in place), seems like some of the caps are messed. I just can't open up the cover on the actual board, as they basically sealed the power wire around one end. I think I'll suggest a replacement.

Since they're getting half the voltage, the capacitor that decides if the cheap TDA chip-amp is on or off might not be at a sufficiently high voltage for it to stay on stably. The chip doesn't deliver a lot of current on that pin, so it might as well just be draining it faster than it is getting charged.

That said, just get some new speakers and blow those up with a shotgun.
The idea of any hi-fi system is to reproduce the source material as faithfully as possible, and to deliberately add distortion to everything you hear (due to amplifier deficiencies) because it sounds 'nice' is simply not high fidelity. If that is what you want to hear then there is no problem with that, but by adding so much additional material (by way of harmonics and intermodulation) you have a tailored sound system, not a hi-fi. - Rod Elliot, ESP

I like the way you think. I won't be able to get my hands on the 870 for a while . I'll get pics though.

That's a 220 to 110 converter. What he would need is 110 to 220.
I need around tree fiddy.

No. He has speakers from Europe that are 220V and are using them in Canada that is 110V so he needs to convert 220V>110V

He has speakers that need 220V and his power outlet is 110V. In order to get 220V into his speaker PSU, he needs to make that 110V into 220V.

He needs to make the 110V in the wall to 220V. Not the other way around.
