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 against 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.
