Phantom power supplies

    Does anyone here use external phantom power supplies?

    I blew up the phantom power on my Apogee Mini-Me :evil: It was accidental but due to my own stupidity -I let a probe slip while measuring voltages in an AKG pattern box, and created a short that sent 120v into the mic input! It now crackles on one channel when phantom power is turned on. Having it fixed would cost as much as a phantom power supply, but I know many people prefer to use external supplies anyhow, for the same reasons that they don't like wall warts for preamps.

    Just wondering what people think. I'm looking at the 4 mic AT power supply.

    Cheers

    You should probably have your mini-me repaired. That dose of 120V a/c most likely zapped more than just the phantom supply. Even if your mini me is passing signal, those input components are probably not working at full performance any longer.

    Thanks Zilla

    I don't suppose there's much point in discussing nice pre's and mics if they're passing through something that doesn't work right. I'm spending a lot on having my mics brought up to spec. so I suppose I should do the same with this.

    Those preamps are going to take a little longer to acquire :(

    PS it's at times like these that I hate surface mount electronics. Round 1 to Kurt!

    Following your advice to have my Mini-Me checked out,
    I am rather pleased that the damage is minimal, and is relatively easy to fix. It's behaving as if a rather high voltage hit it, but not 120V. I find that odd, as the AKG schematic shows this as the control voltage for the mic pattern I was testing. Anyway, I'm delighted it has not been fried competely.

    Thanks for the advice :)

    Since this is unoficially dead, I'll mention that I have an Apex APP 22. It comes in a sturdy box, has 2 channels of 48 volt phantom, and uses the kind of plug in the back of a computer instead of a wal wart. Seems to do the trick and only set me back $65 'dollars light,' (about 50 Yankee bucks)

    Happy am I.

    I'm told the Audio technica 4 channel unit is also good but I couldn't get it to Canada in less than 5 weeksso I went this route.

    Cheers

    Thanks Keith
    I've been looking at the Audio Technica, but I never thought about the Apex, but I'll look into it :cool:

    Cheers
