It is the world’s first fully redundant microphone in a wearable housing—providing an all-in-one solution for critical live sound and broadcast applications that require back-up miking.

To ensure live wireless microphone backup in cases of frequency cross-talk, low battery packs, or connector or element damage, audio engineers and sound technicians regularly wire voice talent with two separate microphones and signal paths—a complex, time-consuming workflow that can lead to inconsistent sound quality and cable clutter, while weighing the wearer down with cumbersome hardware.

With the CO2-8WL, production professionals can mike up talent in half the time and count on stable, consistent audio performance in live, broadcast or streaming scenarios, thanks to built-in dual microphones with perfectly matched frequency and sensitivity elements. Both miniature microphone elements are water, makeup and sweat proof—making them ideal for use under hot stage lights and in outdoor productions.

The patent, which covers dual-element microphone design in a wearable housing, is the fourth awarded to Point Source Audio in just three years; the company also holds a patent for its CM-i3/CM-i5 modular, lightweight in-ear headsets and two patents for its EMBRACE Earmount microphones, which allows head-worn microphones to be easily concealed on the wearer.

These patents reinforce Point Source Audio’s position as a leading innovator of wearable miniature microphone technology and reflects the company’s culture of innovation that aims to elevate the user experience while solving real-world problems.

“Exceptional sound quality is our baseline,” says Point Source Audio President James Lamb. “But it’s not just about the audio superiority of a product; we take a hard look at the ways people are using audio tools in their jobs and develop products in response to those real-world challenges. We always focus on the usability of a product, whether that’s the microphone, the housing or an accessory. Products like the CO2-8WL make the process of redundant miking fast and seamless, so sound engineers can focus less on technology and more on getting their job done.”

It’s this philosophy that led Point Source Audio to develop such groundbreaking audio tools as the SERIES8 line of waterproof miniature microphones, EMBRACE concealed earmounts, and the interactive Mic Finder tool, which takes the guesswork out of selecting the right microphone for specific applications.

Point Source Audio’s award-winning products are in use on Broadway and the West End on high profile theatre productions including Hamilton and To Kill a Mockingbird, and among other prestigious venues including the San Francisco Opera, Lincoln Center, and Berklee College of Music.
