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

    Next generation microphones
    After a long search for a suitable matched pair of large condenser microphones I chose the OC818 Dual Set. My expectations were not met, they were exceeded. And many thanks to Mario for his patient and thorough interactions. Well done!
