A Legendary Capsule Heritage, Redesigned for the Modern Studio
Designed around the handmade ceramic "CKR12" capsule modeled on the dimensions of the classic CK12, the OC818 continues the large-diaphragm sonic aesthetic that has marked countless recordings. This architecture is combined with modern electronics for top-level stability, production consistency, and reliability.
Who Is It For and What Are Its Uses?
Ideal for studios, engineers, and demanding creators, the OC818 excels in vocal recording, acoustic guitar, piano, overheads, ensembles, and sound design. Its multiple polar patterns, low self-noise, and very high SPL capability make it a versatile choice, from intimate vocals to the most dynamic percussive sources, in both mono and stereo.
Features and Innovations Serving Sound Capture
Microprocessor-Controlled Polarization
Internal control of polarization voltages ensures sharp and repeatable pattern transitions. Coupled with the OCR8, it allows remote adjustment of patterns to optimize the soundstage without interrupting the artist.
Bass Management, Headroom, and Outputs
Two types of analog low-cut filters offer three settings (40 Hz and 80 Hz at 2nd order, 160 Hz at 1st order down to 80 Hz then 2nd order below) to control proximity effect and structural noise. The -10/-20 dB pads increase headroom before saturation, while the dual output allows separate recording of each diaphragm for precise polar pattern shaping in post-production. The "Dual Set Plus" pack includes everything needed for coherent and repeatable stereo pairs.

Questions frequently asked
Is the OC818 Black Dual Set Plus suitable for recording vocals and acoustic instruments?
The CKR12 ceramic large-diaphragm capsule is suitable for vocals, acoustic guitars, and pianos. Its equivalent noise level of 9 dB SPL (A) supports capturing quiet sources.
What polar patterns are available on this Austrian Audio microphone?
Five modes are offered: omnidirectional, cardioid, supercardioid, figure-eight, and a customizable preset. Microprocessor-controlled bias ensures repeatable pattern switching.
Can the two diaphragms be recorded separately?
The dual outputs allow capturing each diaphragm separately to adjust the directional pattern during post-production.
What is the maximum SPL supported by this studio microphone?
With switchable pads of -10 dB and -20 dB, the maximum SPL reaches 158 dB SPL. Without attenuation, it is rated at 148 dB SPL. This headroom suits dynamic percussive sources.
What power supply and connectivity are required?
A balanced XLR connection and 48 V phantom power are required. The output impedance is 275 ohms, and the recommended load impedance is above 1 kohm.
