Austrian Audio OC818 Studio Set - Large-diaphragm Condenser Mic with Multiple Polar Patterns Overview:

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.

• Handmade CKR12 ceramic capsule : Made to the same critical dimensions as the classic CK12 capsules
• Multiple polar patterns : Cardioid, omnidirectional & custom programmable
