Does a pre-amp have "electronic" circuitry?

I bought a "M-Audio Tampa" from the US, and since I live in Europe, I bought a power converter (120v-220v).

However, on the box it says:
WARNING: Do not use with TV, PC, VCR and things with electronic circuitry.

What will happen if i try it out? Is there a risk here?

Thank You
 
I think the problem lies in the fact that your converter doesn't convert the Hz difference, only the Volts. Which would make some things not work correctly.

Don't know if it can be harmful to the actual equipment though.
 
Are you sure you even need the converter?

There should be a little sticker next to the power input telling you what voltages you can run the unit on.

I bought a M-Audio DMP-3 from the US and it runs off US and European voltages, I just needed to buy a UK adapter because the plugs are different.
 
Yes, of course it has electronic circuitry.

About the only electric thing that does NOT have it are lamps and old power tools. I have no idea what they actually expect you to use with that converter...

However, the TAMPA is driven with a 12VAC converter (according to the manual at least), which means that what you SHOULD get is a 220V 12VAC converter instead. You should be able to get that from your local M-Audio dealer.
 
Thanks for the reply's !

Do not use with Tv's, VCR's, PC's, Etc (a mic preamp?)...however it says you can use it with hairdryer's and Radio's amongst other things. I suppose nothing can happen, but I just don't want the Tampa to "blow up".
 
I think this has to do with the frequency. I don't think it's still the case, they use crystals now, but the line frequency used to be what TV signals used to be synchronized to. 50 Hz in Europe dictates the 25fps frame rate used there, and the 60 hrz dictates the US and Japan 30 fps, well 29.97 now with that darn color crap! But as far as it blowing it up, I doubt it, but I don't know for sure.
 
I'd by a 220VAC to 12VAC adapter because that's still what you should use.

Having a 220VAC to 110VAC and then a 110VAC to 12VAC adapter just makes no sense.

That said, it's probably safe to use the 220-110VAC adapter. It's just kinda silly. ;)
