Power converters -- 220 to 110

Recommended Posts

Well, I shall soon be headed for the world of 220 volts, and this raises questions about amplification. I'm guessing that prices overseas will be much higher for amps, so I'd prefer to take my own (it won't cost me anything to move it, since the new job is moving me). I know that converters exist...does anyone here have experience with them? Are they reliable & feasible? Anything I should know? Thanks in advance!

I don't know, but I'd be leary of using a converter for something as sensitive as MI equipment.

 

Have you considered having the factory convert the power supply to 220?

 

How long are you planning on staying?

 

I know my Eden WT-330 can be easily converted to 220 volts, but I don't know what you're running (that Genz-Benz combo, right?).

lol we sell a converter at radioshack, but i wouldn't reccomend it for your amp

If you look at the standard 220 volt outlet here in the US, you will see that it is actually just doubled 110 volt lines.

 

Open up your fuse/switch box and look at the fuse/switch that is for your dryer or electric range. This will give you an idea of what I'm talking about.

 

This may or may not be feasible for you, but you can always bring your own sockets and convert it at the box by tapping off of 1 side of the inbound line and the ground. Be sure that power is off at the main switch. Test with something cheap!

 

We used 220 - 110 converters when I was in Kuwait/Iraq. They were the big, heavy, expensive kind for industrial applications.

Many devices are switchable for 110/220(ish) volts; either with a switch on the back (usually by the fuse holder / power lead socket), by opening the casing and moving the connectors on the transformer, or by returning it to the factory and having them swap certain components in the power supply. I bought my QSC PLX off eBay and it cost less than $50 for QSC to switch the voltage and service the amp.

You may care to check the frequency of the A/C where you're going. Some countries use 50Hz, rather than 60Hz. It's easy/reliable for a transformer to convert voltage, but I wouldn't trust a converter to convert frequency too.

I don't think the frequency matters much - a transformer rated for 60Hz will have a slightly lower current capacity at 50Hz but not drastically so. And I don't think a rectifier circuit cares what frequency the AC is at.

Brilliant! I think that'll be the way to go.
