Real sound. Real easy. The OC16 combines a handcrafted CKR6 capsule with clear, direct sound and everything you need to start creating. Fixed cardioid keeps things simple, while two high-pass filters add control. From vocals and acoustic instruments to streaming and amps, it’s the straightforward Austrian Audio choice for home studios, creators, musicians, and everyday recording sessions alike.
Five patterns. Almost any source. The OC616 combines its handcrafted CKR12 capsule with clear, direct sound, massive headroom, three high-pass filters, and two pads. Vocals, instruments, drums, amps, rooms, stereo, studio, or stage – it adapts without hesitation. Built for engineers and musicians who need one serious microphone ready to take on whatever the next session brings.
One pattern. Serious focus. The OC18 combines its handcrafted CKR6 capsule with rich, smooth sound, precise cardioid performance, massive headroom, and factory calibration for consistent results. From studio vocals and acoustic instruments to drum overheads, broadcast, and demanding live productions, it’s built for engineers and musicians who know exactly what they need – and want it done exceptionally well.
Record now. Decide later. The OC818 combines its handcrafted CKR12 capsule with rich, smooth sound, dual outputs, wireless control, 255 polar patterns, and powerful software tools. Shape directionality, stereo, and even immersive audio after recording. From flagship vocals and instruments to complex stereo workflows, it’s a complete recording platform built for engineers who want maximum control and creative freedom.
Four microphones. One unmistakable Austrian Audio DNA. A microphone family built to set the standard. From the essential OC16 to the no-limits OC818, these four bring together cutting-edge capsule technology, Open Acoustics, uncompromising sound, and years of engineering expertise. Closely related. Built to the same standards. But with four very different personalities, strengths, and ways of working.
They may look alike. They don’t work alike. Explore the differences, hear them for yourself, compare features and specs, and find the one that fits the way you create.
