Product Description

Shure SM89

 condenser shotgun microphone can be used for theater sound reinforcement, spot news coverage, or wildlife recording, thanks to its distant pickup characteristics suitable for on-location film and television production. The SM89 discriminates at a distance in favor of desired dialogue or effects and against ambient noise, even in noisy surroundings.

The SM89's on-axis frequency response is very smooth an extended. For clarity and speech intelligibility, a slight presence rise optimizes the high-frequency response to compensate for high-frequency losses. A low-frequency roll-off minimizes pickup of wind, mechanical vibration, ambient noise, and rumble without affecting voice frequencies. The off-axis response is virtually free of comb-filter effects. This is important when it is impossible to aim the mic precisely or when it is desirable to pick up dialogue or sound from moving sources.

Features
  • Designed especially for location film and TV production, theater sound reinforcement, and spot news coverage

  • Highly directional polar pattern optimized for distant pickup

  • Smooth, wide on-axis response

  • Greatly suppressed side pickup with minimum comb-filter effects

  • Two low-cut frequencies, switch selectable

  • Low impedance, high sensitivity

  • Extremely low hum, noise, and RF pickup

  • Uses readily available 11 to 52 Vdc phantom supply

  • Rugged and reliable, operates over wide range of temperature and humidity

  • Extremely lightweight, can be suspended on fishpole for long periods of time without operator fatigue

  • Aircraft-grade materials used throughout

  • Supplied with foam windscreen and strong luggage-grade carrying case
Specification

Type: Pressure gradient/line combination

Transducer: Condenser

Polar Pattern: Hypercardioid at low frequencies, lobar at frequencies above 1 kHz, symmetrical about axis

Output Impedance:
Rated at 150 ohms (100 ohms actual)
Recommended minimum load: 800 ohms (May be used with loads low as 150 ohms with reduced clipping level)

Sensitivity: (at 1,000 Hz):
Open Circuit Voltage: -33 dBV/Pa (22.2 mV)
1 Pascal = 94 dB SPL

Output Clipping Level (at 1,000 Hz, under 0.5% THD)
