Neumann U 87 Ai Condenser Microphone - Nickel

Offering a choice of three switchable polar patterns (omnidirectional, cardioid, and figure-8), the U 87 Ai gives you impressive flexibility when it comes to exploring different recording techniques. With two 87s, you can implement stereo techniques such as spaced pair (A/B), X-Y (including Blumlein), ORTF array, and mid-side (M-S). For full orchestra, add a third 87 for the minimalist — and highly effective — Mercury Living Presence technique: three spaced omni 87s across the orchestral soundstage, centered above the conductor's podium.

Neumann produced the original U 87 from 1967 to 1986, when it was replaced by the current version, the U 87 Ai. The U 87 Ai features upgraded electronic components; however, the capsule design remains unchanged. The modern circuitry increases the mic's operational headroom by reducing the resistance through which the capsule bias voltage is supplied. This gives you 10dB higher sensitivity for identical sound pressure levels and improves the signal-to-noise ratio by 3dB.

If you're using the U 87 Ai to capture a loud source, the microphone's switchable 10dB pre-attenuation pad comes in handy. With the pad activated, the mic accepts sound pressure levels up to 127dB — perfect for miking tom toms or a dimed guitar amp stack.

An additional switch engages the mic's low-frequency cutoff, which reduces undesirable mud and rumble at the input of the microphone amplifier. This setting also compensates for proximity effect, the bass boost that all pressure gradient transducers exhibit when placed very close to a source.
