I bought some wireless microphones of ebay. Now they were meant to come with a convertor to change the plug from what I believe is US to UK. They didn't. So I have been using a shaver adapter I had. I seem to be getting feedback, and have worked this out to be the plug. Now the adapater I am using says for shavers only, and I wondered if I should be using a more specific one, and if so what one. Also, I am pretty sure I can't, but can I just put a UK plug on it. The voltage is only 10 different, but I think the amps is different.

?

IIRC Voltage in the US is 110V. Putting a plug on a US device and plugging it into a UK supply (220-230V) is going to result in a few fizzles and fireworks!

The plug has 6A 250V written on it, maybe its not US?

What voltage[s] do they work at, nominally? (Some devices support multiple voltages with a selector switch.)

If it is designed to run on a 250V supply, then it will be fine to put a UK plug on it.

I can only assume that it has come with a european two-pin plug on - which means that you can use it via a "shaver adapter" type plug, but the device will not be earthed.

Having said that, fitting a UK plug means it will still not be earthed, as there will only be two wires (live and neutral) in the cable.

Tell me more about the system, or point me to a link, I may be able to help.

If it's American the problem is that the electricity flows slightly slower than it does in the U.K.

I bought an American ipod and whenever I listen to stuff it sounds like the chipmonks as the electricity is making the songs play quicker.

It's the other way around using a U.K. one in America.

How have you come to the conclusion that the wrong sort of plug is the cause of the feedback?

Because I can get it to stop, by fiddling with the plug! smile

j-mark wireless microphone JM-306

Basically a receiver which plugs into the mains, and 2 wireless mircophones. I bought it a couple of months ago and can't find the link any more.

Yeah you can whack a UK plug on that no problem.

Don't forget that US volts are smaller than UK ones.
Something to do with the imperial measurements they use.

You positive on this one, I bought them for a mate for his wedding speeches, and as these are taking place at the weekend, want to make sure I'm not going to blow them up! smile

Some power supplies are global ie operates 100v - 240v and it should state this on the unit.

However in this case I think its just a euro model with a euro plug and not US (why do you think its US). You can just chop it of and stick a uk plug on but this will void your warranty.

You can get a uk adapter that wraps around the two pin plug and srews down tightly (best choice) or just buy a travel set in WHsmiths.

Its got 2 thin metal pins, not like a shaver has i.e. like this

The diagram worked in the edit window! smile Its got 2 flat straight pins, not rounded. Maybe it is continental, I can't remember what the plugs look like.

Just buy a travel set to be sure. You have already used it on UK power so its no problem. Also your feedback problems I doubt are related to the shaver plug.

Probably to much gain on the input of the mic to receiver making it over sensitive.

For quick setup put the output at 3/4 and turn mic gain up just so your voice can be adequately heard.

Set you mixer input gain to 0db whilst talking in a "real word" style. All should be fine.
