Static Microphone

A more sophisticated version of the classic U 87. Its 5 polar patterns, two-position high-pass filter and switchable attenuator ensure maximum flexibility.

ARTICLE N° 9276
  • The U 89 is a universal studio microphone.
  • Its grille protects a dual-diaphragm capsule.
  • A rotary selector under the grille allows you to choose from five different polar patterns, so the microphone can be easily adapted to large sound sources, when musicians are spread over a wide area, or for recording at great distances.
  • The built-in preamp accepts sound pressure levels of up to 134 dB SPL without distortion - a figure that can rise to 140 dB.
  • Another rotary selector activates a high-pass filter, effective from 80 Hz or 160 Hz.
  • Acoustic operating principle Pressure gradient transducer
  • Directionality Omnidirectional, wide cardioid, cardioid, hypercardioid, bidirectional (figure of 8)
  • Frequency response 20 Hz to 20 kHz
  • Sensitivity at 1 kHz, load 1 kOhm 8 mV/Pa
  • Nominal output impedance 150 Ohms
  • Recommended load impedance 1 kOhm
  • Input noise level, according to CCIR 468-3 28 dB
  • Input noise level, to DIN/IEC 651 17 dB (A)
  • Signal-to-noise ratio, to CCIR 468-3 66 dB
  • Signal-to-noise ratio, to DIN/IEC 651 77 dB
  • Maximum SPL level, for THD = 0.5% 134 dB
  • Maximum SPL, at THD = 0.5%, pre-attenuation activated 140 dB
  • Maximum output voltage 800 mV
  • Dynamic range of integrated microphone preamp, to DIN/IEC 651 117 dB

Applications
The look of the U 89 is similar to that of the U 87 - but it's smaller and lighter, and offers five different polar patterns (instead of three), as well as a higher maximum sound pressure level. So it's easier to use this microphone for different applications.
Polar patterns
In addition to the usual polar patterns (omnidirectional, cardioid and bidirectional), we have added a hypercardioid and a wide cardioid position. Compared to a standard cardioid pattern, the hypercardioid pattern attenuates sounds coming from the sides more effectively. As for the wide cardioid, it is very practical for recording sound sources spread over a certain aperture.
Acoustic characteristics
The microphone is side-incident - the Neumann logo must face the sound source. The large-diaphragm capsule has a very flat frequency response, for all polar patterns, over a wide angle. The frequency response curves are flat up to 10 kHz, with a pick-up angle of ± 100°.

As a result, the U 89 i has a very smooth diffuse-field response, for all polar patterns; an important aspect in a reverberant environment, where reflections arrive from all directions on the microphone capsule. The tonal quality of the acoustic information is not affected when it is picked up by the microphone.

These characteristics are obtained without recourse to corrective resonance effects.

The capsule is mounted in a flexible manner to avoid any transmission of solid-borne noise.
Filtering and attenuation
The microphone's built-in preamp accepts sound pressure levels of up to 134 dB SPL without distortion. With a self-noise level of 17 dB (A), the total dynamic range is 117 dB. The maximum sound pressure level can rise to 140 dB SPL when the rotary attenuation switch (-6 dB) is in the ON position.

Another rotary switch under the grille activates a high-pass filter with a switchable cut-off frequency of 80 Hz or 160 Hz. This filter suppresses low-frequency interference, but maintains a flat frequency response, even when recording at close range, when proximity effects could distort the sound spectrum.

In the LIN position, the high-pass filter acts very low in the spectrum, with a very steep slope, to prevent the output transformer from being overloaded by undesirable subsonic frequencies.
Safety and reliability
All exposed surfaces of the capsule, including the diaphragms, are at ground potential. This technology makes them immune to electrical and atmospheric interference, as well as contamination by microscopic particles and dust.
