Flexible for All Your Needs
The C30 features a small microphone head attached to a flexible mini gooseneck, as well as a minimal profile that won’t attract attention away from your choir. The 30’ (9m) attached Canare® Star Quad cable resists twisting due to temperature and humidity changes, so you can rest assured that the microphone will stay put once it has been properly aimed.

There is also a giant organ very close to the ChoirMics, which is the largest organ in the state of Minnesota. It is a miracle that we can get as much sound from the choir with the organ and mics placed where they are. It is a real testimony to the exceptional quality of the Earthworks microphones.
