Austrian Audio OC818 Dual Set Plus

The Austrian Audio OC818 Dual Set Plus is a premium, professional-grade microphone system designed for critical studio, broadcast, and live applications. Centered around the handmade CKR12 ceramic capsule—a modern evolution of the legendary CK12—the OC818 is a large-diaphragm condenser that combines vintage sonic character with groundbreaking digital control.

The "Dual Set Plus" is a comprehensive stereo recording solution, featuring two factory-matched OC818 microphones and a full suite of professional accessories for advanced stereo configurations.

Key Features

* Handmade CKR12 Capsule: Engineered and built in Vienna, this ceramic capsule ensures extreme consistency, allowing any OC818 to be match-paired with another. 



* Dual Output Technology: Featuring a secondary mini-XLR output on the rear, the OC818 allows you to record the front and rear diaphragms independently. This enables "re-mic'ing" the polar pattern in post-production. 



* Remote Control & Plugin Suite:

* PolarDesigner Plugin: Change or automate polar patterns across 1–5 frequency bands in your DAW after the recording is finished. 



* PolarPilot App: (Requires optional OCR8 Bluetooth Dongle) Real-time wireless control over polar patterns, high-pass filters, and pads via iOS/Android. 



* StereoCreator & AmbiCreator: Specialized plugins for X/Y, M/S, Blumlein, and Ambisonic B-format processing. 



* Advanced Analog Circuitry: Despite the digital control options, the audio path remains 100% analog, ensuring sonic purity.
