Consistent performance! Engineered and manufactured in Austria, its high sensitivity and low self-noise means it can handle everything from a whisper, to extreme SPLs without distortion, making it the perfect choice for studio, live and broadcast applications. The unique ceramic capsule design is so consistent, the OC18 can be match-paired with any other OC18 or paired with any OC818 set in cardioid mode. The heart of the OC18: CKR6 Ceramic Capsule Making Passion Heard! We bring passion to everything we do, and nobody brings more than our engineering team. Every CKR6 ceramic capsule is handmade in-house at our facility in Vienna and now we are developing the next generation of transducer and microphone builders to serve our expanding customer-base.
