Austrian Audio OC-B6: Pure Power for Bass Drum Recording

The Austrian Audio OC-B6 brings large-diaphragm condenser technology to kick drum miking, setting a new standard for clarity and headroom. Purpose-built for bass drum, this model captures every nuance from vintage warmth to modern attack, without pre-EQ or coloration. The OC-B6 stands out as a studio and stage solution that thrives on punishing SPL, while remaining compact and easy to position. A condenser microphone designed for challenging environments, it goes where others can't.

Breakthrough Features for Modern Drummers

Unlike most kick drum microphones, the OC-B6 features the unique CKR6-B capsule—a 1" ceramic-based large-diaphragm element custom-tuned for extreme SPL. Its 220° swivel head and robust, clip-free design allow for precise placement, even inside cramped shells or at the port. Reliability and flexibility are at the forefront of the design, making it a true asset for stage or studio use.

Designed for Unmatched SPL and Clarity

Recording bass drums at high volume requires a microphone that withstands extreme sound pressure without breaking up. Engineers benefit from the OC-B6's ability to be placed anywhere, free from concerns about distortion.

• Capsule Type:Condenser — delivers detailed transient response and full-bodied lows.
• Engineers can record even the most aggressive playing without distortion, thanks to the 170 dB maximum SPL.
• Frequency Range:18 Hz – 20 kHz — ensures all low-end energy is faithfully captured, right down to the sub-bass.

Intelligent Filtering and Signal Integrity

Low-frequency management is essential for modern drum miking. The OC-B6’s integrated 25 Hz subsonic filter eliminates inaudible rumble and infrasound, preserving headroom and preventing muddy mixes. This keeps the recording clean and focused even in loud live environments.

• Subsonic Filter:25 Hz — removes unwanted low-end rumble for a punchier, clearer kick sound.
• Impedance:108 Ohm — optimized for compatibility with modern audio interfaces and consoles.

Precision Engineering, Inside and Out

Inside, a discrete, chip-free electronic design ensures rapid transient response and uncompromised fidelity. The cardioid polar pattern targets the kick drum while reducing stage bleed. Durability is ensured for both touring and studio applications.

• Characteristics, Polar Pattern:Cardioid — isolates the kick drum and limits unwanted noise.
• This model is handcrafted in Vienna, guaranteeing precision and reliability.

Who Is the OC-B6 For?

Engineers and drummers needing clarity and impact in their kick drum tracks will find the OC-B6 a powerful tool. Designed for professionals in live and studio settings, this microphone allows total freedom in mic placement and excels across all genres.
