Austrian Audio OC-B6

The OC-B6 is the world’s first large-diaphragm condenser

bass drum microphone – handcrafted in Vienna and

designed to capture the full impact of your kick with

clarity, punch, and authenticity.

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.
