Austrian Audio OC818 Large-Diaphragm Condenser Microphone Studio Set, Black

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.
