CKR12 Ceramic Capsule

At the heart of Vienna is a deep tradition of love for music.

At the heart of our revolutionary OC818 and OC18 is an equally passionate commitment to sound and engineering excellence. Each of these Large Diaphragm Condenser (LDC) microphones has a handcrafted Austrian Audio CKR12 ceramic capsule as its heart and the heart & soul of any classic microphone is the capsule. There are very few people that can design, let alone construct, a classic edge-terminated capsule. There is also the question of building them by hand in Europe. The good news is that the skill, knowledge, and tradition live on at Austrian Audio.

We bring passion to everything that we do, and nobody brings more passion to making our CKR12 ceramic capsule by hand then our very own Monika. See, Monika has been building high-end transducers since the mid-1990s. Her hands have carefully constructed some of the most respected audio tools in the world. When she wasn’t making classics, she was training a new generation on the art and craft of proper transducer construction. That tradition and heritage continues as Monika has made every CKR12 to date along with most of our microphones and is now training the next generation of historic transducer and microphone builders at Austrian Audio.
