Austrian Audio / OC818 black Studio Set

Austrian Audio's OC818 is the world's first multi-pattern & dual output condenser microphone with wireless control options.

Featuring a CKR12 dual ceramic capsule, handmade in Vienna, Austria, multi-polar pattern, high-pass filter/pad, open acoustic technology, 255-level directional design/remote control with the PolarPilot app, and even dual-output post-production with the PolarDesigner plug-in, this microphone combines tradition and modern technology.


■Handmade CKR12 dual ceramic capsule
Designed and handmade in Austria with the same critical dimensions as the legendary CK12 capsule. Resistant to touch noise due to suspension structure

■Multi-pattern
Unidirectional, superunidirectional, omnidirectional, bidirectional, designable presets in the PolarPilot app

■Analog polarity voltage control
Remote control of directivity and various functions via Bluetooth from the PolarPilot app

■3-stage high-pass filter and 2-stage pad
Filter: 40 Hz/80 Hz/160 Hz, Pad: -10 dB/-20 dB

■Dual output
You can output and record the front/back of the diaphragm separately.

■Stereo pair anytime
Since the individual sensitivity differences shipped are adjusted to within 1dB, any two, regardless of whether they are OC818 or OC18, can be used as a stereo pair.
