My At 4040 just stopped working, no sound ?
I am going through an RME interface through the phantom input, I checked and ran my Shure SM58 and that works fine

Use a volt meter to measure the phantom power. Measure DC voltage between pins 2 and 1 and then between 3 and 1. They should measure the same and be between 12-48 volts dc.
