The white-finished version of the U851R, the phantom-powered U851RW features a PivotPoint® rotating output connector, UniSteep® filter and UniGuard® RFI-shielding technology. Offering outstanding speech intelligibility and transparent sound quality for surface-mount applications, the U851RW accepts interchangeable condenser elements - available for boundary microphones in cardioid, hypercardioid and omnidirectional polar patterns. With a heavy die-cast case and silicon foam bottom pads to minimize coupling of surface vibration to the microphone, the U851RW is equipped with self-contained electronics, eliminating the need for an external power module.

  • Designed for surface-mount applications such as high-quality sound reinforcement, professional recording, television, conferencing and other demanding sound pickup situations
  • PivotPoint® rotating output connector allows cable to exit from either the rear or the bottom of the microphone
  • Superior off-axis rejection for maximum gain before feedback
  • UniGuard® RFI-shielding technology offers outstanding rejection of radio frequency interference (RFI)
  • Self-contained electronics eliminate need for external power module
  • Small-diameter UniPoint® capsule near boundary eliminates phase distortion and delivers clear, high-output performance
  • Heavy die-cast case and non-slip silicon foam bottom pads minimize coupling of surface vibration to the microphone
  • Low-profile design with low-reflectance finish for minimum visibility
  • Available in two colors: black (U851R) and white (U851RW)

  • Open Circuit Sensitivity: 34 dB (19.9 mV) re 1V at 1 Pa
  • Impedance: 200 ohms
  • Maximum Input Sound Level: 134 dB SPL, 1 kHz at 1% T.H.D.
  • Dynamic Range: 108 dB, 1 kHz at Max SPL
  • Signal to Noise Ratio: 68 dB, 1 kHz at 1 Pa
  • Phantom Power Requiremens: 11-52V DC, 4 mA typical
  • Switch: Flat, roll-off
  • Weight: 9.2 oz (262 g)
  • Dimensions: 4.25" (108.0 mm) long, 3.31" (84.0 mm) maximum width, 0.91" (23.0 mm) height
  • Output Connector: TB3M-type
  • Cable: 25.0' (7.6 m) long, 0.13" (3.2 mm) diameter, 2-conductor, shielded cable with TA3F and XLRM-type connectors

 

With its half-space unidirectional polar pattern, low-profile design, and outstanding sound quality, the PRO44 is ideal for conference tables, podiums, lecterns and other installed-sound uses. This versatile boundary mic\'s self-contained electronics eliminate the need for external power modules. The PRO44 is equipped with a wide-range condenser element with low-mass diaphragm for superior performance.

Designed to deliver easy, flexible control in conference and boardroom installations, the versatile U891Rx cardioid condenser boundary microphone features a touch-sensitive on-off switch that can be set to three modes: press-on/press-off, press to talk, and press to mute. The phantom-powered microphone is equipped with a unique PivotPoint® rotating output connector and an LED status indicator. UniGuard® innovations offer unsurpassed immunity from radio frequency interference; interchangeable elements are available in cardioid, hypercardioid and omnidirectional polar patterns; an 80 Hz low-cut UniSteep® filter reduces pickup of low-frequency ambient noise. The microphone's heavy die-cast case and silicon foam bottom pads minimize coupling of surface vibration to the microphone. The unit's self-contained electronics eliminate the need for an external power module.
