The New Viennese Original

The OC818, entirely designed and handcrafted in Vienna, represents the pinnacle of the Austrian Audio large diaphragm microphone series.

Its excellent technical features, such as low self-noise and high sensitivity, and especially its revolutionary design approaches, make it one of the most advanced microphones for both studio and live use. Since the CKR12 capsule, which is sonically inspired by the legendary CK12 capsule, is made of ceramic, the production variance is so low that every OC818 pairs perfectly with another OC818 or OC18 (OC818 in cardioid mode) to create a "Matched Pair."
