Austrian Audio OC616 Condensatormicrofoon voor studio

Multi-Pattern Studio Condenser Built Around the CKR12 Capsule

The Austrian Audio OC616 is a large-diaphragm condenser microphone designed for engineers and producers who want one workhorse mic that adapts to every source in the session. At its core sits the CKR12 — a handcrafted 1" true condenser capsule built in Vienna with an edge-contacted design and a ceramic isolator that improves unit-to-unit consistency.

From intimate vocals to broadcast-ready speech, from acoustic guitar to cranked amplifiers, this model covers the full tracking list in a project or home studio.

Open Acoustic Technology and Capsule Engineering

What separates this microphone from typical large-diaphragm condensers is the way the capsule is suspended inside the body. Open Acoustic Technology reduces reflective surfaces and contact points around the diaphragm, so sound reaches the capsule openly from every direction without comb-filtering artifacts. The CKR12's ceramic isolator keeps performance consistent across units — important for engineers planning matched-pair stereo work.

Five polar patterns — cardioid, hypercardioid, wide cardioid, omnidirectional, and figure-of-eight — turn a single mic into a flexible stereo tool. Mid/Side, Blumlein, and dual-source setups all become practical without buying a second microphone.

Polar Patterns and On-Body Controls

Pattern selection happens directly on the microphone body, giving the engineer immediate control over directivity during tracking. Cardioid handles the bulk of close-mic duties; hypercardioid tightens rejection for stage or loud sources; wide cardioid softens proximity effect; omni captures room and ensemble ambience; figure-eight enables Mid/Side and Blumlein stereo techniques.

• Polar Patterns: Cardioid, Hypercardioid, Wide Cardioid, Omnidirectional, Figure-of-Eight — five-position selector on the microphone body
• Switchable High-Pass Filters: 40 Hz (2nd order), 80 Hz (2nd order), 160 Hz (1st order down to 80 Hz, 2nd order below) — three settings for cutting rumble, tightening low end, or controlling proximity effect
• Switchable Pads: -10 dB and -20 dB — engage when tracking drums, percussion, or cranked guitar and bass cabinets

Capsule, Sensitivity, and Headroom

The CKR12 is a 1" large-diaphragm true condenser capsule with an edge-contacted design and a ceramic isolator. Its ceramic isolator delivers low distortion and consistent behavior between units, while the open acoustic design keeps transients fast and the high end uncolored.

• Capsule Type: 1" CKR12 large-diaphragm true condenser, handcrafted and individually measured in Vienna
• Frequency Range: 20 Hz – 20 kHz
• Sensitivity: 13 mV/Pa — consistent output across all five polar patterns
• Equivalent Noise Level: 13 dB SPL (A-weighted)
• Maximum SPL: 147 dB (157 dB with pad engaged)
• Dynamic Range: 134 dB

Connectivity, Power, and Physical Specs

The OC616 runs on standard 48 V phantom power and connects via a 3-pin XLR. Its symmetrical 108 Ω impedance and >1 kΩ load impedance spec make it compatible with any professional preamp. The body is compact enough for tight mic placements around drum kits or in compact vocal booths.

• Connector: XLR 3-pin
• Impedance: 108 Ω (symmetrical)
• Load Impedance: > 1 kΩ
• Phantom Power: 48 V (< 3 mA current draw)
• Dimensions: 157 x 66 x 34 mm
• Weight: 345 g

Who the OC616 Is For

The OC616 is the right choice for project-studio engineers, home recordists, and vocalists who need one microphone that can move between sources without swapping gear. Producers tracking full sessions — vocals, acoustic guitar, drum overheads, bass cab, room mic — get the polar-pattern flexibility of a multi-pattern mic with the headroom to handle loud sources cleanly. Stereo work is unlocked through Mid/Side or Blumlein setups using the cardioid and figure-of-eight patterns.
