I decided to make battery packs for my ART II. So in my stupidity I didn't look at the unit before I built and plugged in the battery box ::)
The plug needed to have the center tip negative, instead of positive. So I plug in the battery pack and I smell smoke, then figuring out what I have done. So I reversed the tip, and I have the following:
When I used the battery pack I made on the jack, the power button is one while in the off position, 48V, or 12V position.
When I put in two 9V batteries, it appears to operate correctly, with no power light on off, and power lights on the 12 and 48 volt positions.
Now I'm afraid of plugging my mics in to test it...what is the chance it will fry my mics.
I figure since it smoked, I could take it apart and find the burned component and replace.
Note to self, ALWAYS check polarity becofe making power cables :o

You might be ok depending on what you fryed maybe a voltage regulator maybe more it depends on the duration of the reversal.

I probably had it in no more than 3 seconds

What is an ART II is that an effects processor?
-
It's a phantom power box for mics. It puts out either 12V or 48V.
I'm just scared to put my mics into them, as I don't want them fried.

You may want to try a multimeter to see if the phantom box is accurately giving off the correct voltage at either setting (12v/48v). Once you know how many volts the box is supplying, then you'll know for sure if it's ok to plug your mics in.
My guess is....you probably won't hurt the mics by plugging them in. If anything, the ART may be supplying too low of a voltage.

That's what I figured....may be easier to just get another?

Easier sure, but test it out first. If you don't have a DMM you can grab one at Wally World or Rat shack under $20.

a great investment!! ^^
The best investment for people that are building power supplies and hey with a digital one you can see the polarity before you connect it to your phantom supply :P
-
I have a DMM...just looked up the pin outs on an XLR....I will be certain to look at it a few times....PRIOR to just the output ;D
-
OK...I checked the output....on the 12V switch it puts out 11.2 V.....on the 48V side it puts out 45.0V this is one both inputs.
I would assume it should be ok to plug in???
Thanks everyone for their help.

sounds like as much as you could expect from that box! do it to it.
