Austrian Audio OC-B6

The OC-B6 represents Austrian Audio’s bold new approach to bass drum miking. As the world’s first large-diaphragm condenser microphone purpose-built specifically for kick drum, it delivers powerful low-end, exceptional transient clarity, and virtually unlimited headroom — equally at home on stage or in the studio with the very impressive 170 dB SPL.

The new OC-B6 Bass Drum Microphone delivers excellent results from all standard kick-drum mic positions. Unlike many other kick mics, the OC-B6 is designed to perform consistently whether it is placed outside the drum, right at the port, or inside the shell. This flexibility allows engineers to adapt quickly to different styles, stages, and recording situations without switching microphones.

With the OC-B6, you have one mic that covers every approach to kick-drum miking – making it a reliable and versatile solution for both live and studio environments.

Built around Austrian Audio’s CKR6-B capsule, the OC-B6 delivers unmatched SPL handling (>170 dB) and a pure, unfiltered sound that lets engineers shape tone exactly as they want — from vintage warmth to modern attack.

The 220° rotatable head and ultra-compact design make placement effortless even in tight stage or studio setups, while the rugged construction ensures it performs flawlessly night after night.
