nah, generally its ok to send phantom to a dynamic mic like an sm57.

its ribbon mics that'll get blown if you send them phantom. you'd know if you had a ribbon mic (y)

Thank you.

Is there a preferred way to use my SM57 with the E Mu 1616,
Phantom on or off?

Thanks,

The only mics to worry about re: Phantom power, are Ribbons.

But if you don't need it, (as with the SM57) turn it off anyway.

Back in the old days, I'm told they actually used to demagnetize dynamic mic outputs (like the SM57 and others) that had been exposed to phantom power over long periods of time. (I had a nice chat with Wes Dooley about this a few months back.) Some dynamic mics do sound a bit better without the phantom power applied anyway, and it just makes good sense to turn it off if you don't need it.

Thank you very much. :D
