The Austrian Audio OC818 is a premier, large-diaphragm condenser microphone that marries the legendary heritage of Viennese microphone design with groundbreaking modern technology. At its heart is the handmade CKR12 ceramic capsule, engineered to the same critical dimensions as the classic CK12, delivering a transparent and natural sound that excels on vocals, piano, and drum overheads.

What sets the OC818 apart is its dual-output design, allowing you to record the front and rear diaphragms independently via the secondary mini-XLR port. When paired with the PolarDesigner plug-in, you can manipulate polar patterns across five frequency bands after recording, providing unprecedented control over room spill and proximity effect.
