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 simple dual-channel recording, which allows you to design custom polar pattern responses across five frequency bands via the open-source PolarDesigner plug-in. 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. Being 48 VDC phantom powered, the OC818 does not require batteries or an external power supply.
