Neumann U 87 Ai Multi-Pattern Condenser Microphone

The Neumann U 87 Ai is not just a microphone; it's a studio legend. For over 50 years, this multi-pattern condenser microphone has been the gold standard for professional audio recording, revered for its smooth, refined, and iconic sound. Its unmatched versatility, thanks to three selectable polar patterns (omnidirectional, cardioid, and figure-8), makes it the ideal choice for a wide range of applications, from capturing the subtle nuances of vocals and speech to the dynamic power of acoustic guitars, drums, and even full orchestras. With its classic design, balanced frequency response, and exceptionally low self-noise, the U 87 Ai ensures every recording is delivered with clarity, detail, and that unique midrange presence that defines the Neumann legacy. Whether you're in a professional broadcast studio or a home recording setup, the U 87 Ai brings professional-grade quality and timeless sound to your productions, making it a sound investment for any serious creator.

Key Features

• Legendary Sound: The U 87 Ai is a true studio classic, trusted by professionals worldwide for its smooth, transparent, and iconic sound signature.
• Versatile Polar Patterns: Easily switch between omnidirectional, cardioid, and figure-8 patterns to adapt to any recording situation and acoustic environment.
• High SPL Handling: Equipped with a switchable 10 dB pre-attenuation pad, allowing it to handle extremely high sound pressure levels up to 127 dB without distortion.
• Low-Cut Filter: The switchable low-frequency roll-off helps to reduce unwanted subsonic noise and compensate for the proximity effect, ensuring a clean and clear recording.
• Precision Engineering: Features a large dual-diaphragm condenser capsule and a FET circuit with a transformer-balanced output for maximum signal integrity and minimal self-noise.
