German tube mics: Power supplies Condenser Microphones

German tube mics: Power supplies

So I bought this Neumann M582 for some folk sessions, to use on acoustic guitar and the like.

I plugged it in, ran it in to my laptop, and got signal just fine.

Then I noticed on the power supply it says 220v ~ 50Hz, and wondered if I was going to have problems using it here in the States at 110v ~ 60Hz?

Should I be using a step down transformer between the wall and the power supply? I've used these mics in studios and can actually remember a step down transformer attached to one of the tube mics, but maybe it was a U47, or a CMV563.

Electrically semi-illiterate (and all of the sudden paranoid),

I'm not sure how you got your mic and power supply to sound "fine" and work in the U.S. at 110 volts if it was wired up for European 220 volts. Many of these power supplies have internal jumpers which can be set for either U.S. current or European 220, and its possible yours has been set up for U.S. voltage and you don't realize it. Excellent, reliable, and clean step up/step down transformers can be purchased for about $50 to convert the voltage but if your power supply is already set up correctly for 110 you could damage it by putting 220 volts into it. You need to see who made your power supply, is an original Gefell or an aftermarket? If you can find out who made it, you need to call them and make sure everything is OK.

I'm very sure you wouldn't be happy with mic's sound if it was done for 220 and runned on 110. So if it is ok than someone already fixed that thing.

It had an old original (or I would assume) American standard plug, that probably came with it, or was an accessory. It is an original power supply. I wasn't thinking about the switch being internal for the 220v to 110v. I'm sure that's what it is, and it's already been set. Sounds great I'm excited


Thanks,
Aaron
