Consistent performance
Engineered and manufactured in Austria, its high sensitivity and low self-noise means it can handle everything from a whisper, to extreme SPLs without distortion, making it the perfect choice for studio, live and broadcast applications. The unique ceramic capsule design is so consistent, the OC18 can be match-paired with any other OC18 or paired with any OC818 set in cardioid mode.

The same handcrafted design as the OC818 - Classic cardioid

Handcrafted CKR6 ceramic capsule - like the CKR12 capsule, but with single diaphragm

Every Austrian Audio OC18 and OC818 is within 1dB of each other - Making any two microphones a stereo pair
