The Neumann U 87 is probably the best known and most widely used Neumann studio microphone. It is equipped with a large dual-diaphragm capsule with three directional patterns: omnidirectional, cardioid and figure-8. These are selectable with a switch below the head grille.
A 10 dB attenuation switch is located on the rear. It enables the microphone to handle sound pressure levels up to 127 dB without distortion.
Furthermore, the low frequency response can be reduced to compensate for proximity effect.
The U 87 Ai is addressed from the front, marked with the Neumann logo. The frequency response of the cardioid and figure-8 directional characteristics are very flat for frontal sound incidence, even in the upper frequency range. The microphone can be used very close to a sound source without the sound becoming unnaturally harsh. By means of a high-pass filter interferences through subsonic and low frequencies are reduced remarkably.
The dual-diaphragm capsule is elastically mounted and protected by a large head-grille. A switch below the headgrille selects the three directional patterns: omnidirectional, cardioid and figure-8. A window above this switch shows the symbol of the selected characteristic.
The letter A in the name indicates a more recent generation, as compared to the U 87 i microphones that were built from 1967 to 1986. Modifications apply to the electronic components of the microphone only; the capsule remained unchanged.
The present-day circuitry increases the operational headroom of the U 87 Ai by supplying the bias voltages for the capsule through a reduced resistance. The result is a higher sensitivity of 10 dB for identical sound pressure levels, and an improved S/N ratio of 3 dB.
Filter and attenuation
A switch located at the rear attenuates the sensitivity by 10 dB. When this switch is activated, the microphone accepts sound pressure levels up to 127 dB (equivalent to a sound pressure of 45 Pa) without distortion.
An additional switch at the rear allows to change the microphone's cutoff frequency. This reduces low frequency interference directly at the input of the microphone amplifier.
This setting also compensates for the unavoidable bass boost that occurs with all pressure gradient transducers when they are used at close distance (proximity effect).
The cardioid characteristic maintains a smooth frequency response at a distance of 30 to 40 cm, the figure-8 characteristic even at a distance of 15 to 20 cm.
Sharing the gain structure and Class A, fully discrete transistor circuitry design of the popular Daking Mic Pre IV, the Mic Pre One additionally features a unique variable high-pass filter and ships in a freestanding 'DI-style' steel enclosure, ensuring both strength and noise immunity.
Essentially a single channel of the Mic Pre IV, the Mic Pre One features switchable phase, 20dB mic input pad and +48V phantom power, plus a selectable 1/4-inch line/hi-z instrument input, all utilizing relays with gold bi-furcated contacts. Two large knurled aluminum knobs control the variable high-pass filter (0-200Hz) and continuously variable input gain, which is complemented by a full-width, twenty-segment bi-color LED meter. The rear of the unit offers a Jensen transformer-isolated mic input and fully-balanced XLR output, plus a 1/4-inch line output. A fourth connector introduces DC power from the external power supply to the unit.

Noted Brad Lunde, president of TransAudio Group, "This Mic Pre One is the very definition of value - a Daking-designed high-end mic pre for those who only need one channel. It's ideal for pros on tour and studios that seek to locate the mic pre in the vocal booth for short cable runs. Small project studios on a limited budget, can now use the same high-end sounding gear as the pros."
Mogami Premium-Grade Studio Microphone Cable
The Gold Series uses selected Mogami Neglex "Studio Quad" Oxygen Free Copper cable. This 4-conductor cable actually cancels noise caused by poor ground planes and high RF or electromagnetic fields. The ultra-low-noise spiral shield is the most densely wound available. All this engineering helps cure many of the problems encountered in a project or home studio, creating a much quieter recording environment with vastly improved Dynamic Range.
Virtually every major recording facility in the world is wired with Mogami cable. This means that just about any music you choose has been recorded using Mogami in the audio chain. This cable is famous for unmatched accuracy, extremely low noise and remarkable flexibility. Top engineers rave about its amazing clarity and silent background. If accuracy in reproduction is your goal, this is the cable for you.
