From Austrian Audio

The New Viennese Original

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. As the unique ceramic capsule design is so consistent, any OC818 is match-paired with any other OC818, and when in cardioid mode, it can also be match-paired with any OC18, its affordable, smaller sibling.

PolarPilot App

Our free PolarPilot app (Android and iOS) allows real-time wireless control over your analogue patterns, high-pass, and pad in realtime via Bluetooth

 • Save, recall, and share favourite settings

 • Discover and create 255 discrete polar patterns

 • One setting may be stored in OC818 for use without the PolarPilot app

 • The OC818 is always pure analogue: only the analogue bias voltages are being governed remotely

 • Switching also is always analogue

 • No digital in either the audio or bias paths. It’s everything you want, with none of what you don’t

 • 60 second OC818 clipping monitor/logger

 • Wireless control from the comfort of your chair
