Product Overview

The U 87 Ai mt Stereo Set (008506) doubles the legendary performance of the U 87 Ai. Each microphone in this set is meticulously tested to ensure they are sonically identical, providing a flawless stereo image with a rock-solid phantom center. Featuring the same K 87 dual-diaphragm capsule and transformer-balanced FET circuitry that defined the "Neumann Sound," 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 stereo recording technique, from XY and ORTF to Mid-Side (M-S) and Blumlein.

Product Description

The Standard, Multiplied by Two:

The U 87 Ai mt 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 tools needed for mission-critical stereo applications. Whether used as a main microphone pair for a symphony orchestra or as spot mics for acoustic instruments, these microphones provide a smooth, refined sound that brings an immediate "produced" quality to every recording.

Advanced FET Circuitry & K 87 Capsule:

The "Ai" designation marks the modern era 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 electronic advancements, the capsule design remains unchanged from the original 1960s specification. The result is a microphone that maintains its classic warm character while meeting the ultra-low noise requirements of modern digital recording environments (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 guitar stacks.

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

Professional Matte Black Aesthetic:

The "mt" (Matte Black) finish is more than just a style choice; it is highly functional for film, television, and stage use, as it minimizes light reflections. The microphones are handcrafted in Germany 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 mt Stereo Set is a complete professional package. It includes two EA 87 mt elastic suspensions (shock mounts) specifically color-matched to the microphones to isolate them 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.
