    Can I connect a mic with a mono 1/4" male plug to a female 1/4" plug wired as stereo, and plug that into my mixer with a XLR connector wired as stereo?

    I've read some posts that look like you can, and some say it may damage equipment. I'd be shorting the ring to the sleeve, if I'm understanding it right.

    Thanks.

    You won't damage anything, but you'll have an impedance mismatch, which will affect the sound and reduce the signal level significantly.

    You need a matching transformer - many make them.

    Thanks, I'll look into matching transformers.

    Is my question a common scenario? It's not a issue on mic's with XLR connectors, right? I ran across some mic's with a male mono 1/4" and got confused. Are these type of mic's real cheap or something?

    High impedance mics aren't really all that common anymore.

    And yes, they tend to fall in the budget category.

    Thanks Loudboy. It's makes more sense now.

    It's not mono to stereo-it's unbalanced to balanced. And, the 1/4" unbalanced (mono) mic is high impedance and needs to be low impedance to plug into the balanced input on your mixer.

    So, as loudboy says, you need a high Z to low Z transformer.

    Would plugging it into the balanced Line input of my mixer do the same thing as going thru an impedance transformer and plugging it into the MIC input of my mixer?

    Thanks.

    So there's no quality advantage one way or the other?

    Thanks.

    No, it will not do the same thing. You need to plug in to the mic input to get the right amount of gain. Line inputs do not have enough gain for mics. You need the transformer to make the mic low impedance and then plug it into the mic input on your console.

    Really, why pay $50 for a transformer for a crappy hi impedance mic when you can buy a new Shure SM-58 for $99?

    Thanks for all the great input! I'm keeping notes. I would never have known line inputs don't have enough gain for mics. I know I'm beating this thread to death, but I'm new at this and am I learning alot.

    Shure SM58 - $65
    transformer - $12
    GLS Audio ES58 - $30

    I may do all three! Thanks again!

    Yes. Do not over complicate this.

    well, one out of three at least ;)

    get the real 58 (where are you seeing them for $65?) and don't bother with the other junk.

    Your sig states

    "Just a sound man, can't play a note"

    and you're not familiar with this sort of thing?

    Had to ask
