Austrian Audio OC818 Multi-pattern Large-diaphragm Condenser Microphone

Austrian Audio OC818 Multi-pattern Large-diaphragm Condenser Microphone

Designed by a team of former AKG personnel, the Austrian Audio OC818 Studio Set is a large-diaphragm studio condenser microphone offering detailed audio capture and immense sonic customization for producers and engineers in personal and commercial recording facilities. The handmade 1″ ceramic capsule features two gold-plated polymer membranes to enable multiple polar patterns. Utilize the 5-position switch to set the OC818 to figure-8, hypercardioid, cardioid, omnidirectional, or wide cardioid. Each diaphragm is routed to a separate output connector for dual-channel recording, which allows you to design custom polar pattern responses across five frequency bands via the open-source PolarDesigner plug-in or achieve a tweakable stereo image thanks to the StereoCreator plug-in (also open-source).

Alternatively, the secondary output can be connected to the optional OCR8 Bluetooth module if you wish to enjoy convenient wireless control and selection of 255 polar patterns via the free iOS/Android PolarPilot app. Front-panel switches are provided for easy access to the pad and roll-off settings. Set the pad to -10 or -20 dB to avoid distortion when miking loud sources such as drums or guitar cabinets. Activate the high-pass filter at 40, 80, or 160 Hz for attenuation of low-frequency problems including rumble and proximity effect. The OC818’s housing is constructed of zinc-aluminum alloy for strength and durability. The OC818 Studio Set includes a 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.
