I'm planning on miking my Guitar amp using an Audiobix iTwo with the M7 condensor mic (supplied in the kit) and a Shure SM57 dynamic mic.
I've read warnings to not use Phantom power for dynamic mics. Thing is, it looks as though the phantom power switch controls both inputs simultaneously. Any tips on what settings I should use when mixing condensor/dynamic types? Thanks |
Phantom power is a low current +48V (or thereabouts) dc voltage put on both signal wires (2 and 3) using the shield (pin 1) as the return wire.
On most professional dynamic mics there is no electrical connection between the shield (mic body) and the mic capsule (between pins 2 and 3), so the capsule is floating wrt. the shield. Putting 48V on it (even with wires 2 and 3 crossed) won't hurt a bit. If in doubt check the mic's user's manual. Ribbon mics are notorious for not having a floating 'capsule'. Phantom power will damage them. |
