A valuable tool to help you make recordings with better sound quality: the Austrian Audio OC18. 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 sound source with excellent results. Austrian Audio microphones are rigorously tested with state-of-the-art measurement systems and are precisely matched within a strict tolerance of 1dB. This means you can confidently use your OC18 alongside another OC18 (or the company's cardioid-tuned OC818 multi-pattern set) in a stereo pair configuration and achieve stunning results.

Exceptional results from any sound source

Austrian Audio puts all the knowledge gained from more than 300 years of combined experience into its products. The company's proprietary CKR12 capsule carries this wisdom, and a superior handcrafted capsule is the heart of any classic microphone. Following a fixed cardioid polar pattern, the OC18 uses the single-diaphragm version of the CKR12 capsule, which - in conjunction with the microphone's custom electronics - delivers excellent results when used for vocals, acoustic guitar, piano, drum overheads, strings, brass , percussion and ambient capture. Additionally, the OC18's robust native maximum SPL capability of 148 dB - further augmented by the inclusion of selectable -10 dB and -20 dB pads - also makes it ideal for louder sound sources such as drums and electric guitar cabinets. .

Versatile cardioid polarity

If you had to choose just one polar pattern for all the microphones in your studio, cardioid would be the one. While we recommend having multi-pattern microphones - like the Austrian Audio OC818 - in your microphone collection for complicated recording situations and advanced stereo miking techniques, cardioid microphones will be your "go-to" microphones for the vast majority of recording tasks. and sound reinforcement. The OC18 uses the same CKR12 ceramic capsule handcrafted in Vienna as the OC818, but with just a single diaphragm, which keeps the cost lower. After all, if you don't need multiple polar patterns, 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 microphone like the OC18 will see constant use in your studio.
