Explore the sonic possibilities
The OC818 offers four selectable onboard polar patterns: Figure-8, Supercardioid, Cardioid, and Omni, giving you immense flexibility when it comes to exploring the sonic possibilities offered by different recording techniques. The fifth setting is Preset mode, which works in tandem with the optional Bluetooth dongle that plugs into a port on the rear of the mic body and lets you program custom patterns. Austrian Audio microphones are rigorously tested on state-of-the-art measurement systems and precision matched to within a stringent 1dB tolerance which means that with two of these excellent microphones, you can confidently implement stereo techniques such as Spaced Pair (A/B), XY (including Blumlein), ORTF array, Mid-Side (M-S), and Spaced Omni (with or without a center mic). It's worth noting that a single OC818, with its two separate XLR outputs, is a stereo microphone in and of itself. However, by employing two OC818s, your options will expand exponentially.
Dual mode and PolarDesigner
The second output on the back of the OC818 delivers the signal from the rear capsule membrane, while the front membrane is output via the normal XLR plug. Simply connect the OCC8 mini XLR cable supplied with your OC818 and set the polar pattern switch to the cardioid setting (the center position with the dual-cardioid icon). The OC818 will now work in Dual mode, with both capsule diaphragms being routed independently. In Dual mode, you can record the two signals to separate tracks and use the PolarDesigner plug-in to subsequently modify the polar pattern in post production. PolarDesigner even lets you independently choose the polar pattern for up to five different frequency bands. For example, imagine how a pair of room mics with a tight supercardioid pickup in the low frequencies, figure-8 for the mids, and omnidirectional for the highs would sound on a drum kit in a great-sounding room!
Real-time remote control
With Austrian Audio's OCR8 Bluetooth module (available separately) and the PolarPilot app for iOS and Android, you can remotely control your OC818 from your smartphone or tablet. Powered by the 48-volt phantom that powers the mic, the OCR8 is activated via the Preset mode switch setting (the "" position all the way to the right). Once paired with your device, the PolarPilot app gives you complete wireless control over the OC818's polar patterns, highpass filters, and pads. The app also features an overload monitor that displays a red bar if the signal is too loud. In that case, engage the 10dB pad to reduce bias voltage to the capsule and protect the mic's internal circuitry from clipping.
The heart of any classic mic is a superior handmade capsule, and this wisdom is borne out in the Austrian Audio's proprietary CKR12 capsule. In keeping with its multi-pattern design specification, the OC818 uses the dual-diaphragm version of the CKR12 capsule, which in concert with the microphone's custom electronic circuitry delivers excellent results when used for vocals, acoustic guitar, piano, drum overheads, strings, brass, percussion, and room capture. What's more, the OC818's robust native 148dB maximum SPL capability further increased by the inclusion of selectable 10dB and 20dB pads also makes it ideal for louder sources such as tom toms and electric guitar cabinets.
