The new viennese original! Engineered and manufactured in Austria, The OC818 is Austrian Audio’s premier, professional, large diaphragm microphone. Its high sensitivity, low self-noise and ability to handle everything from a whisper to extreme SPLs make it the most advanced microphone for studio, broadcast and live applications. As the unique ceramic capsule design is so consistent, any OC818 is match-paired with any other OC818, and when in cardioid mode, it can also be match-paired with any OC18, its affordable, smaller sibling. The heart of the OC818: CKR12 Ceramic Capsule. Making Passion Heard. We bring passion to everything we do, and nobody brings more than our engineering team. Every CKR12 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.
