Austrian Audio OC-B6

Meet the OC-B6 - the world's first large-diaphragm condenser microphone purpose-built for kick drum.
Handcrafted in Vienna and built to survive brutal sound pressure levels beyond 170 dB, the OC-B6 captures the full force of your kick with absolute clarity and zero compromise.

No pre-EQ. No hype. No distortion. Just pure, unfiltered kick drum tone - from deep vintage boom to razor-sharp modern attack. Shape it your way. This is condenser detail where no condenser has dared to go before.

The OC-B6 delivers consistent, uncompromising sound from every classic kick-mic position - inside the shell, right at the port, or outside the drum. Unlike conventional kick microphones, it doesn’t lock you into a single sound.

Its 220° swivel head makes placement fast and precise, even in tight setups, while the ultra-compact and rugged design performs flawlessly on stage and in the studio. One microphone. Every approach. Every genre. No swaps. No second guesses.

The OC-B6 is engineered without shortcuts. Its discrete electronics deliver lightning-fast transient response and extreme headroom - no chips, no bottlenecks, no loss of information. A precisely tuned 25 Hz subsonic filter removes inaudible rumble and infrasound, preserving headroom where it matters most. The integrated stand thread eliminates clips entirely, making setup faster, cleaner, and more reliable - night after night. This is professional kick-drum engineering, stripped down to what truly matters.

At the heart of the OC-B6 is the CKR6-B - a specially developed 1" large-diaphragm true condenser capsule, evolved from Austrian Audio’s ceramic capsule technology and re-engineered for extreme SPL.

By doubling the diaphragm-to-electrode distance and lowering the resonance frequency, the CKR6-B achieves virtually unlimited headroom while subtly shaping the low-frequency response for kick drum perfection. The result: a condenser capsule that stays clean, stable, and musical - even at levels that destroy ordinary microphones.
