Earthworks C30/C-B Cardioid Condenser Hanging Gooseneck Choir Microphone

The C30 ChoirMic™ is the ultimate problem solver for miking choirs and other venues with high ceilings.

Choir microphones have always presented a unique design and installation challenge – the traditional solution is to use an angle guide on the microphone’s lead to aim towards the performance venue. The problem with this approach is that either a very small microphone had to be used to keep aimable weight within practical limits – or locate the microphone’s electronics at some considerable distance from the element – inviting losses and noise. The ChoirMic™ Series solves all of these problems. Our hanging choir microphones provide pristine audio quality without spotlighting and more gain before feedback while picking up almost no sound from the rear of the microphones. They are ideal for miking choirs and orchestra or band in front of the choir.

The Definition of Balance
A wide pickup pattern at all frequencies, with over 30db of rear rejection. The result is the pure sound of your choir.

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.
