Austrian Audio OC18 Cardioid Condenser Microphone

Versatile Cardioid Condenser in the Viennese Tradition

Handcrafted in the heart of Vienna, the City of Music, the OC18 is a versatile large-diaphragm condenser microphone with a fixed cardioid polar pattern, -10dB and -20dB pads, and a three-position, switchable highpass filter. You can use the OC18 on any source with excellent results. Austrian Audio microphones are rigorously tested with state-of-the-art measurement systems and are precision matched to within a stringent 1dB tolerance. This means you can confidently use your OC18 along with another OC18 (or the company’s multi-pattern OC818 set to cardioid) in a stereo-pair configuration and assure stunning results.

Outstanding results on any source

Austrian Audio pours into their products everything they have learned in more than 300 years of combined experience. The company’s proprietary CKR12 capsule bears this wisdom, and a superior handmade capsule is the heart of any classic mic. In keeping with a fixed cardioid polar pattern, the OC18 uses the single-diaphragm version of the CKR12 capsule, which — in concert with the microphone’s custom electronic circuitry — delivers excellent results when used for vocals, acoustic guitar, piano, drum overheads, strings, brass, percussion, and room capture. What’s more, the OC18’s robust, native 148dB maximum SPL capability — further increased by the inclusion of selectable -10dB and -20dB pads — also makes it ideal for louder sources such as tom toms and electric guitar cabinets.

Cardioid polar pattern

If you had to choose only one polar pattern for all the mics in your studio, cardioid would be the one. Although we certainly recommend having multi-pattern microphones — such as Austrian Audio’s OC818 — in your mic locker for tricky recording setups and advanced stereo miking techniques, your cardioid mics will be your “go-to” mics for the vast majority of recording and sound-reinforcement tasks. The OC18 uses the same handmade-in-Vienna CKR12 ceramic capsule as the OC818, but with only a single diaphragm (CKR6), which keeps the cost down. After all, if you don’t need multiple polar patterns, then why pay for them? With the OC18, you’re getting almost exactly the same microphone as the OC818 with identical sonic performance. A great-sounding cardioid condenser mic like the OC18 will enjoy constant use in your studio.
