Designed by a team of former AKG personnel, the Austrian Audio OC818 Dual Set Plus is a matched pair of large-diaphragm studio condenser microphones offering detailed audio capture and immense sonic customization that's ideal for stereo miking solo instruments, drum kits, and ensembles. The handmade 1" ceramic capsule features two gold-plated polymer membranes to enable multiple polar patterns. Utilize the 5-position switch to set the OC818 to figure-8, hypercardioid, cardioid, omnidirectional, or wide cardioid. Each diaphragm is routed to a separate output connector for dual-channel recording, which allows you to design custom polar pattern responses across five frequency bands via the open-source PolarDesigner plug-in or achieve a tweakable stereo image thanks to the StereoCreator plug-in (also open-source).

Alternatively, the secondary output can be connected to the optional OCR8 Bluetooth module if you wish to enjoy convenient wireless control and selection of 255 polar patterns via the free iOS/Android PolarPilot app. 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 OC818's housing is constructed of zinc-aluminum alloy for strength and durability. The OC818 Dual Set Plus includes two shockmounts, two mic clips, a stereo bar, two mini 5-pin XLR to 3-pin XLR cables, two windscreens for mitigating noise from breaths and blasts of air, and a protective carry case for easy transport and storage of the entire bundle.

Dual Set Plus vs Live Set

• Both bundles include two OC818 microphones, two mic clips, two windscreens, and two mini-XLR cables
• The Dual Set Plus bundle adds two shockmounts, a stereo bar, and a large case to house the entire bundle

Precision Capsule

• CKR12 ceramic capsule is handmade in-house at Austrian Audio's facility in Vienna
• Made to the same critical dimensions as the classic CK12 capsules
• Matched within 1 dB of every other OC18 or OC818

Studio Sound Quality

• High sensitivity and low self-noise means it can handle everything from a whisper to extreme SPLs without distortion
• Two-stage pad (-10 or -20 dB) to prevent distortion
• High-pass filter with three positions (40, 80, or 160 Hz) for reduction of low-frequency rumble and excessive bass

Microphone Features

• 5-position polar pattern switch for figure-8, hypercardioid, cardioid (dual-cardioid mode when using the secondary output), omnidirectional, and "preset mode," which defaults to wide cardioid, but can be set to anything via the free iOS/Android PolarPilot app and optional OCR8 Bluetooth dongle (required for PolarPilot control)
• Microprocessor control of polarization voltages allows remote controlled polar pattern settings
• Dual outputs for recording each diaphragm separately
• Balanced 3-pin XLR main output
• Mini 5-pin XLR secondary output
• Includes mini 5-pin XLR to 3-pin XLR adapter cable for secondary output
• 48V phantom powered
• Includes mic clip and windscreen per mic
• Includes protective carry case
• Debuts Austrian Audio's Open Acoustics Technology
• Works with select downloadable open-source plug-ins for extra flexibility

PolarPilot App

• Wireless control of polar pattern, pad, and high-pass filter settings in real time via Bluetooth (optional OCR8 required)
• Save, recall, and share favorite settings
• Discover and create 255 discrete polar patterns
• One setting can be stored in OC818 for use without PolarPilot app
• No digital technology in the audio or bias paths
• 60-second clipping monitor/logger

PolarDesigner Plug-In

• Craft different polar pattern responses across 1-5 crossover bands
• Store, recall, and share presets
• Powerful Terminator AI for eliminating or rescuing selected frequencies and instruments
• Equalization control for imprinting the tonality of free-field or diffuse-field idealized responses
• Per-band solo/mute
• Supports comprehensive automation
• Linear phase
• Optimized for use with the OC818 in dual-output mode, but works with any dual-output source

Stereo Creator Plug-In

• Stereo with one OC818
• Three different stereo techniques with fantastic post-processing possibilities using two OC818s
• One 4-channel recording, three different stereo techniques (X/Y, Mid-Side, Blumlein)
• Adjust spatiality in post processing
• Change stereo width in post processing
• Change orientation in post processing

AmbiCreator Plug-In

• Create an Ambisonic B-format signal with two OC818 microphones
