Austrian Audio OC818 Studio Set
Large-diaphragm condenser microphone with multiple polar patterns, spider mount, mini XLR, mic clip, windshield, case
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.
The heart of the OC818
CKR12 Ceramic Capsule
Making Passion Heard
We bring passion to everything we do, and nobody brings more than our engineering team. Every CKR12 ceramic capsule is handmade in-house at our facility in Vienna and now we are developing the next generation of transducer and microphone builders to serve our expanding customer-base.

Two of these arrived just in time to do a live recording of an audio play, 9 actors on stage. Got a chance to compare - not direct A/B comparisons but enough to recognize the qualities. Other mics on stage were AKG C414 (TLii and ULS), Neumann TLM 103, Audio Technica 4080, ADK 3Zigma Lol 67. Read more
All of them had their merits. The AA OC818s stood out with a buttery low midrange and a silky smooth high end with relatively little sibilance - still very clear. Worked very well with adult male and female voices as well as child characters.
I wonder a bit about the resonance of the grille, it has a definite tone when tapped but did not seem to affect the recording in any unpleasant way. We used the included foam pop filter which - I assume - would reduce such resonance.
The dual mode (i.e. front and back diaphragm) applications are really interesting and I can see them being very useful in studio recording when time with the voice talent is limited. Being able to alter the polar pattern and proximity effect after recording can be very helpful. Also (shhh don't tell anyone!) in dual mode it can be used with some well-known third party mic emulation software -free! ... at least for now.
