Designed by a team of former AKG personnel, the Austrian Audio OC18 Studio Set is a large-diaphragm studio condenser microphone offering detailed audio capture for vocalists, voiceover artists, musicians, and producers in personal and commercial recording facilities. The handmade 1" ceramic capsule features a gold-plated polymer membrane and a cardioid polar pattern, which yields reliable on-axis directivity with enhanced off-axis rejection. Front-panel switches are provided for easy access to the pad and roll-off settings.
Set the pad to -10 or -20 dB to avoid distortion when miking loud sources such as drums or guitar cabinets. Activate the high-pass filter at 40, 80, or 160 Hz for attenuation of low-frequency problems including rumble and proximity effect. The OC18 s housing is constructed of zinc-aluminum alloy for strength and durability. The OC18 Studio Set includes a vibration-reducing shockmount, a traditional mic clip, a windscreen for mitigating noise from breaths and blasts of air, and a protective carry case. Being 48 VDC phantom powered, the OC18 does not require batteries or an external power supply.
Handcrafted Condenser Capsule
Handcrafted CKR6 ceramic capsule like the CKR12 capsule, but with a single diaphragm
Precision Matching
Matched within 1 dB of every other OC18 or OC818 to allow the creation of stereo pairs (additional microphones available separately)
Studio Sound Quality
High sensitivity and low self-noise means it can handle everything from a whisper to extreme SPLs without distortion
Onboard Settings
Two-stage pad (-10 or -20 dB) to prevent distortion and high-pass filter with three positions (40, 80, or 160 Hz) for reduction of low-frequency rumble and excessive bass
