Large-diaphragm Condenser Microphone with Multiple Polar Patterns

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

CKR12 Ceramic Capsule

Making Passion Heard

We bring passion to everything we do, and nobody brings more than our engineering team. Every CKR12 ceramic capsule is handmade in-house at our facility in Vienna and now we are developing the next generation of transducer and microphone builders to serve our expanding customer-base.

The OC818 Studio Set includes:

Vibration-reducing shockmount, a traditional mic clip, a mini 5-pin XLR to 3-pin XLR cable, a windscreen for mitigating noise from breaths and blasts of air, and a protective carry case.
