Austrian Audio OC18 Dual Set Plus Large-Diaphragm Condenser Mics

Precision Stereo Performance Right Out of the Box

The Austrian Audio OC18 Dual Set Plus provides a meticulously engineered, factory-matched pair of large-diaphragm condenser microphones designed for uncompromising stereo recordings. Built in Vienna by a team of former AKG personnel, these microphones deliver the legendary "Viennese sound" combined with modern engineering excellence. This set is the ultimate workstation for studio engineers, drum specialists, and location recordists who require instant phase coherence and lifelike spatial detail when capturing orchestras, acoustic ensembles, or drum overheads.

The Handmade CKR6 Ceramic Heart
At the core of every OC18 is the handcrafted CKR ceramic capsule. By utilizing ceramic instead of traditional brass, Austrian Audio achieves incredible manufacturing consistency. This allows every OC18 to be factory-matched not only to its pair but to any other OC18 or OC818 in cardioid mode. For the engineer, this means flawless stereo imaging and the removal of guesswork during critical setups like X-Y or ORTF recording.

Open Acoustic Transparency
Austrian Audio’s proprietary Open Acoustic technology eliminates unwanted internal reflections by suspending the capsule from three flexible rubber grommets. This internal shock-mounting removes the need for a traditional pedestal, ensuring the frequency response remains neutral, sweet, and transparent. You get the "air" and presence of coveted vintage microphones without the harsh resonances common in older headbasket designs.
