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. Because 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.
