Neumann U 87AI Large Diaphragm Condenser Microphone (B-Stock)

Multi Pattern Large Diaphragm Condenser Microphone for Professional Recording

The Neumann U 87 Ai is a large-diaphragm condenser studio microphone built around the renowned K 67 capsule and designed for critical recording applications. This pressure gradient transducer offers three selectable polar patterns—cardioid, omnidirectional, and figure-8—making it one of the most versatile microphones available for studio vocals, voiceover, orchestral recording, broadcast, and instrument capture. Powered by standard 48V phantom power, it delivers consistent, detailed sound trusted in professional studios worldwide.

Selectable Cardioid Omni and Figure 8 Patterns

With switchable polar patterns, the U 87 Ai adapts to a wide range of recording scenarios. Cardioid mode focuses on front-facing sound while reducing room reflections. Omni mode captures natural room ambience and extended low-frequency response. Figure-8 enables side rejection and is ideal for mid-side or duet recordings. This flexibility makes it suitable for everything from solo vocals to stereo recording techniques.

K 67 Capsule with Wide Frequency Response

The K 67 large-diaphragm capsule supports a frequency range of 20 Hz to 20 kHz, ensuring accurate reproduction across the full audible spectrum. Sensitivity values of 20 mV/Pa in omni, 28 mV/Pa in cardioid, and 22 mV/Pa in figure-8 at 1 kHz provide strong output levels for clean signal capture. The capsule design preserves clarity, detail, and balanced tonal response for both speech and musical sources.

High SPL Handling with Switchable 10 dB Pad

The microphone handles up to 117 dB SPL in cardioid mode at less than 0.5% distortion. Engaging the switchable 10 dB attenuation increases maximum SPL handling to 127 dB, allowing the microphone to capture louder sources such as brass instruments, drums, and guitar amplifiers without overload. This headroom makes it practical for both delicate and high-energy performances.

Professional Studio Electronics and 200 Ohm Output

With a nominal impedance of 200 ohms, the U 87 Ai integrates easily with professional microphone preamps and studio consoles. Its low-noise circuitry and balanced output support clean signal transmission through long cable runs. The microphone requires 48V phantom power and is engineered for consistent performance in demanding recording environments.

Classic Nickel Finish and Robust Construction

Finished in nickel, the microphone measures 56 mm in diameter and 200 mm in length, with a weight of approximately 500 grams. The durable housing protects the internal components during daily studio use. Compatible shock mounts and stand adapters are available separately, allowing users to customize mounting based on studio needs.
