Austrian Audio OC818 Dual Set - Large-diaphragm Condenser Microphones (Silver)

Precision Stereo Imaging Defined

The Austrian Audio OC818 Dual Set Plus is the definitive solution for engineers who demand absolute phase stability and consistency in their recordings. This comprehensive kit provides a pair of factory-matched OC818 large-diaphragm condenser microphones, allowing you to capture everything from delicate acoustic performances to high-SPL ensembles with total transparency. It is the essential choice for professional studio engineers, location recordists, and broadcasters seeking the legendary Viennese sound evolved for the modern era.

Ceramic Core for Unrivalled Consistency
At the heart of each OC818 is the handmade CKR12 ceramic capsule. By evolving the legendary CK12 design into a non-conductive ceramic frame, Austrian Audio has eliminated the humidity-related reliability issues common in vintage brass capsules. This innovation ensures that every microphone delivers a perfectly balanced, detailed frequency response with ultra-low self-noise, providing a transparent canvas that accurately reflects your sound source.

Sculpt Your Polar Patterns in Post
The OC818’s unique dual-output design allows you to record the front and rear diaphragms independently. When combined with the free PolarDesigner plugin, you can modify polar patterns and even adjust the proximity effect long after the recording is finished. This revolutionary workflow lets you target specific frequency bands or remove unwanted bleed, giving you control that was previously impossible with traditional hardware.

Remote Management Without Digital Interference
For hard-to-reach placements, the OC818 system supports the optional OCR8 Bluetooth dongle. This allows you to control polar patterns, pads, and high-pass filters wirelessly via the PolarPilot app. Crucially, the audio signal remains 100% analogue; the app only governs the internal bias voltages. This means you can fine-tune your settings from the sweet spot of your studio monitors without introducing digital noise into your signal path.
