The microphone should be electrically insulated from the holder and hence from the stand. |

The BIPT that came to measure the RFI in the concert hall where my problems started (they measured no abnormal RF, just very high levels of the transmitter at 104 MHz) state that the best way is connecting a ceramic capacitor between the conductors of the mic cable and the earth (10 nanofarad or 100 nanofarad). |

...On phantom powered mics (and other mics with XLR three-pin connectors): Pin #1 and the ground lug of each connector's housing must be connected together, on both cable ends! |

...Then I asked him to use one of my ... cables... between the power supply and the wall panel. Problem solved: no more fuzz. |

On tube mics: Connect ground wire and cable shield together to the pin of the connector that is dedicated to ground and install a wire from ground to make contact with the connector's housing. This connection is often conveniently made at the cable strain relief, where a clamp is screwed into threads of the connector housing. |
