Members Rawkkitten Posted February 5, 2010 Members Share Posted February 5, 2010 Can phantom power damage dynamic microphones? I thought I read that somewhere once. I just got a condensor mic (Shure Beta 187a! Sounds great!) but the rest of my band uses various dynamic mics. There is only one button to turn phantom power on/off for all channels on the mixer. I assume the dynamic mics and other inputs can handle the phantom power even if they don't need it. Am I right about that? Link to comment Share on other sites More sharing options...
Members Mogwix Posted February 5, 2010 Members Share Posted February 5, 2010 Short answer: No. Long answer: Phantom power can damage some ribbon microphones. Applying phantom power to modern dynamics (anything REALLY old might do something weird like shock you, but that's unlikely) won't damage or affect anything, because they're designed to accept it without harm. It's a good idea to avoid plugging in or unplugging any mics connected to phantom power while the system is hot and the levels are up... POP fzz POP. It's a good idea to avoid plugging anything in or unplugging anything while the system is hot and levels are up, anyways. Link to comment Share on other sites More sharing options...

Members oldschooler Posted February 5, 2010 Members Share Posted February 5, 2010 Beta 187A... ??? That mic model is for gangster rappers. It just kills all other mics making it the sole survivor.. Link to comment Share on other sites More sharing options...

Members boseengineer Posted February 6, 2010 Members Share Posted February 6, 2010 I assume you mean "87a". There is no "187", at least not made by Shure Dynamics are fine with phantom, however they can create huge pops when phantom gets turned on/off or when they are plugged or unplugged while phantom is on. Mute the board when rewiring or pushing the button. The pop goes to all outputs (i.e. mains & monitors) so it's not enough just to pull the master faders down, you also need to mute any Aux sends or (best) make sure that all power amps are still off.

I guess I like this mic so much I got excited and added 100. Yes, it's a Beta 87a. Thanks for the helpful information, guys. What makes a mic good for gangsta rap? I like to scream sometimes, but I got this mic because my {censored}ty old mic was feeding back too much and I read some good reviews. Link to comment Share on other sites More sharing options...
Members TimmyP Posted February 6, 2010 Members Share Posted February 6, 2010 No problem so long as the mic cables are OK. If a mic cable were to have a short between pin 1 and either pin 2 or 3, you might get enough phantom current through the mic to damage it. (Andy might be better able to asses the possibility of this.) Link to comment Share on other sites More sharing options...
Members agedhorse Posted February 6, 2010 Members Share Posted February 6, 2010 Generally current is limited to around 7mA, which shouldn't cause any damage. Link to comment Share on other sites More sharing options...
