There is a motion picture accessories manufacturer that makes a barrel
adapting a T-power mic to 48 V phantom. When I tested one for a
customer, I was surprised to find it putting out 48 V to the mic
connector open circuit. A call to their service department and a test
confirmed that the voltage came down to around 10V when the Sennheiser
MKH 415 was plugged in.
But further investigation revealed that at the moment of hot-plugging,
at least one 10 V-rated capacitor in the mic was being pulsed with 16
V. Not good. "Quick and dirty" circuits may work, but that one's risky.
I recommend the Denecke PS-T. It's battery, but it's safe. Disclosure:
I'm a Denecke dealer.
