Description

The Austrian Audio OC-B6 is a purpose-built large diaphragm condenser bass drum microphone, handcrafted in Vienna to capture the full weight, punch and character of your kick. With colossal SPL handling of up to 170 dB, a pure, uncoloured sound and a compact, swivel-head design, it is a flexible solution for both live and studio engineers who want total control over their low-end.
Unlike many pre-shaped kick mics, the OC-B6 delivers a clean, honest signal that responds beautifully to EQ and compression. Whether you are chasing vintage thump, modern click or anything in between, this mic gives you a solid, detailed foundation that slots straight into the mix. Its cardioid pattern and subsonic filter keep unwanted rumble at bay, while the rugged housing and built-in thread make it easy to deploy night after night.

Handcrafted Large Diaphragm Kick Mic
At the heart of the OC-B6 is Austrian Audio’s CKR6-B large diaphragm capsule, engineered specifically to handle the extreme sound pressure levels of a bass drum. This true condenser design captures the full frequency range of your kick, from deep sub lows to the beater attack, with impressive clarity and transient detail. The result is a kick sound that feels powerful and three-dimensional, without losing the natural character of the drum.

Pure, Flexible Sound for Any Genre
The OC-B6 is intentionally free from built-in EQ curves or hyped frequency bumps. Instead, it delivers a neutral, unfiltered signal that gives engineers complete freedom to sculpt the tone to suit the track. From warm, rounded jazz and soul kicks to tight, aggressive rock and metal sounds, the OC-B6 responds predictably to processing, making it a reliable go-to mic for a wide range of styles and sessions.

Effortless Positioning in Tight Spaces
With its ultra-compact body and 220 degree rotatable head, the OC-B6 is designed to fit into tight stage plots and crowded studio setups. The integrated mic thread means you can mount it directly on a stand without a separate clip, then quickly angle the capsule exactly where you want it. Whether you prefer placing the mic inside the shell, right at the port, or just outside the drum, the OC-B6 delivers consistent, usable results from all standard kick positions.

Built to Handle Extreme SPL
Capable of handling up to 170 dB SPL, the OC-B6 takes the most punishing kick hits in its stride. There is no need to worry about overloading the capsule or introducing distortion when players really dig in. A subsonic filter at 25 Hz removes inaudible rumble and stage vibration, helping keep your low end tight and controlled while preserving the musical weight of the drum.

Key Features
World’s First Large Diaphragm Condenser Kick Mic – Specifically designed for bass drum, the OC-B6 combines the detail and speed of a studio condenser with the robustness needed for extreme SPL, giving you a kick sound that is both powerful and highly articulate.
170 dB SPL Handling with Zero Distortion – With headroom to spare, the OC-B6 can comfortably cope with the loudest drummers and most energetic performances, ensuring a clean, reliable signal that does not collapse under pressure.
Neutral, Uncoloured Tonality – No pre-EQ or baked-in voicing means the OC-B6 delivers a pure, flexible sound that you can shape to taste. This makes it ideal for engineers who want one dependable kick mic that works across multiple genres and setups.
Compact 220 Degree Swivel Head – The small footprint, rugged housing and wide-rotating head make positioning quick and precise, even inside the drum or in cramped stage environments, while the built-in mic thread removes the need for an extra clip.
