So i bought a handful of dirt cheap old mics on eBay, and i need to re-wire them to actually be usable. they are all hardwired, mostly with mini-jack connectors, meaning they have only 2 wires to connect, not 3 like most decent mics. basically my question is: i figured out how to attach a male xlr plug to the end of these so they would connect just like all my other mics, but since these are all high impedance mics, would it be better to attach 1/4" jacks and plug them into the direct ins on my mixer? would plugging a high impedance signal into the xlr input on a board cause problems? any insight would be greatly appreciated. thanks.
