Hmmm....did you patch it while phantom power was on? This could definitely cause a problem.

If you just turned it on while the mic was plugged in, it shouldn't be an issue.

Ribbon microphones are like little fuses that don't accept any current. If you have a bad cable that could possibly have intermittents between any of the pins, you risk " popping the fuse". End of story. End of ribbon microphone.

the Royer 121 ribbon mic will tolerate phantom power. For best and safety reasons, turn on your preamp first - ensure that the phantom power is of - then plug the Royer 121 ribbon microphone.

Other ribbon microphones are not as tolerant on phantom power, for that the Royer design is great.
