Earthworks EA-C30 30kHz Hanging Gooseneck Microphones

The Earthworks EA-C30 ChoirMic is a hanging gooseneck condenser microphone with 30’ (9m) cable designed for installation in churches and other venues.

The Challenge

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 Solution: Earthworks C30 ChoirMic

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

With its wide pickup pattern at all frequencies, you can easily cover large groups with just a few microphones. The C30 will reproduce the sound of the choir with incredible articulation and no spotlighting, so no one voice outshines the rest. Instead, the choir will sound like a unified voice. With over 30dB of rear rejection, the C30 has more gain before feedback while picking up almost no sound from the rear of the microphone.

The Earthworks EA-C30 features a small microphone head attached to a flexible mini gooseneck, which allows quick and precise positioning of the microphone. 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. Measuring just .86 inches (22mm) in diameter at its largest point, the C30 practically disappears from view when installed, providing a low profile miking solution.

Options

The C30 includes a 30′ (9m) unterminated cable. The C30-XLR accessory is available for purchase to terminate with an XLR. Standard cable length is 30′ (9m), but can be customized when ordering using accessory C30-CCL. Available in black or white. Available in cardioid or hypercardioid.

The Ultimate Problem Solver

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 minimal 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, noise, etc. Earthwork Audio’s ChoirMics overcome these issues by locating the element on a short flexible extension from the microphone’s body – resulting in excellent response and extremely low noise – while retaining the ability to aim the element at the precise point desired.

Less Is More

With its wide pickup pattern at all frequencies, you can easily cover large groups with just a few microphones. The C30 will reproduce the sound of the choir with incredible articulation and no spotlighting, so no one voice outshines the rest. Instead, the choir will sound like a unified voice. With over 30dB of rear rejection, the C30 has more gain before feedback while picking up almost no sound from the rear of the microphone.

Testimonial

“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.”
