Austrian Audio OC818 - Large-diaphragm Condenser Microphone

The new Vienna classics

Engineered and manufactured in Austria, the OC818 is Austrian Audio’s premier, professional, large diaphragm microphone. Its high sensitivity, low self-noise and ability to handle everything from a whisper to extreme SPLs make it the most advanced microphone for studio, broadcast and live applications.

The Austrian Audio OC818’s unique ceramic capsule design is so consistent that any OC818 is match-paired with any other OC818. Even the smaller OC18 is a perfect match if paired.

Rich Sonic Possibilities
The OC818 offers four selectable onboard polar patterns: Figure-8, Supercardioid, Cardioid and Omnidirectional, 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.  This means you can be confident when using a pair of them for stereo pickup that each OC818 is precision calibrated, regardless of their production date.

Dual mode & PolarDesigner Plugin
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 plug in the OCC8 mini XLR cable supplied with your OC818 and set the polar pattern switch to the cardioid setting (the centre 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 modify the polar pattern in post-production. PolarDesigner even lets you independently choose the polar pattern for up to five different frequency bands.

Real-time Remote Control & PolarPilot App
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.

Once paired with your device, the PolarPilot app gives you full 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.
