Earthworks C30/C-B

The Earthworks ChoirMic Series of 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.

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.

High Definition Response
Earthworks High Definition technology results in an extended high frequency response up to 100kHz.

Accurate Off-Axis Response
The frequency response at 90 degrees off-axis is within 2dB of the on-axis response. This results in extreme accuracy and less microphone usage.

Unobtrusive Profile
The miniature C30 is easily installed in theaters, houses-of-worship, etc
