Product Overview

The U 87 Ai Stereo Set (008505) doubles the legendary performance of the U 87 Ai. Each microphone in this set is meticulously tested and matched to ensure they are sonically identical, providing a flawless stereo image with a rock-solid phantom center. Featuring the famous K 87 dual-diaphragm capsule and transformer-balanced FET circuitry, the U 87 Ai offers a unique combination of linearity and charisma. With switchable Omnidirectional, Cardioid, and Figure-8 patterns, this set is a versatile powerhouse capable of handling any professional stereo technique, from XY and ORTF to Mid-Side (M-S) and Blumlein.

Product Description

The Global Standard, Multiplied by Two:

The U 87 Ai is widely considered the best-known and most frequently used studio microphone in existence. By offering them as a factory-matched Stereo Set, Neumann provides engineers with the precision tools needed for mission-critical stereo applications. Whether used as a main microphone pair for a symphony orchestra or as overheads for a world-class drum session, these microphones provide a smooth, refined sound that brings an immediate "finished" quality to every recording.

Advanced FET Circuitry & K 87 Capsule:

The "Ai" version represents the modern evolution of the U 87, featuring updated internal electronics that offer 10 dB higher sensitivity and an improved signal-to-noise ratio over vintage models. Despite these advancements, the capsule design remains faithful to the original 1960s specification. The result is a microphone pair that maintains its classic warm character while meeting the ultra-low noise requirements of modern high-definition digital recording (12 dB-A self-noise in cardioid).

Precision Controls for Perfect Captures:

On the rear of each microphone, two switches provide essential control over the audio signal:

• -10 dB Pre-attenuation Pad: Allows the microphones to handle high sound pressure levels up to 127 dB without distortion—ideal for loud percussion or brass sections.

• Low-Frequency Roll-off: Engages a high-pass filter to reduce subsonic interference and compensate for the proximity effect during close-miking.

Timeless Nickel Aesthetic:

The classic Satin Nickel finish is the hallmark of the Neumann brand, representing a legacy of German engineering and acoustic excellence. Every U 87 Ai is handcrafted with the same precision that has made the Neumann diamond a seal of quality for nearly a century.

Comprehensive Stereo Kit:

The U 87 Ai Stereo Set is a complete professional package. It includes two EA 87 elastic suspensions (shock mounts) in matching Nickel to isolate the microphones from stand-borne vibrations. The microphones and shock mounts are protected by individual dust covers and housed in a lockable, road-worthy Aluminum Case with custom-cut foam inserts for maximum security during transport.
