Does Phantom Power have any detrimental effects on a dynamic mic? Here's the situation... If I wanted to plug two mics into a Presonus Firebox http://www.sweetwater.com/store/detail/FireBox One being a condenser and one being a dynamic. Since the box only has one phantom 48 switch, this means that there will be power flowing to both mics. It's the dynamic I'm worried about (obviously), could phantom power damage the mic or affect the recording in any way?
