Neumann U 87 Ai Stereo

Neumann U 87 Ai Stereo Set — a premium matched pair of the legendary U 87 Ai large-diaphragm condenser microphones. This iconic model has become the defining standard in professional recording studios, broadcast environments, and orchestral productions worldwide. Known for its transparent, natural, and musical tone, the U 87 Ai is the microphone of choice for vocals, acoustic instruments, and orchestral recordings.

Each U 87 Ai features a dual-diaphragm capsule with three selectable polar patterns — omnidirectional, cardioid, and figure-8 — allowing precise control over pickup characteristics. A -10 dB pad switch ensures distortion-free sound capture up to 127 dB SPL, while the built-in low-cut filter compensates for proximity effect and eliminates low-frequency rumble or background noise. The frequency response remains linear and balanced across all polar patterns, maintaining the microphone’s signature clarity even at close mic placements.

Whether in film, television, broadcast, or studio environments, the U 87 Ai delivers the sonic precision and reliability required by the world’s top engineers. Its ability to reproduce vocals and instruments with remarkable detail makes it indispensable for everything from symphonic recording to solo vocal performance.
