Cardioid Condenser Hanging Microphone

$315 + shipping (includes gst)

Perfect for speech, theater, orchestra and choir sound reinforcement and recording, the U853R cardioid condenser hanging microphone is equipped with UniGuard® innovations that offer unsurpassed immunity from radio frequency interference. With a consistent cardioid polar pattern, the mic offers natural sound from any angle, and superior gain before feedback. It is phantom powered and features an integral 80 Hz low-cut UniSteep® filter that reduces pickup of low-frequency ambient noise. The microphone accepts interchangeable elements, available in cardioid, hypercardioid, omnidirectional and UniLine® line cardioid polar patterns.

  • Designed for suspension over choirs, instrumental groups and theater stages
  • Superior off-axis rejection for maximum gain before feedback
  • UniGuard® RFI-shielding technology offers outstanding rejection of radio frequency interference (RFI)
  • UniSteep® filter provides a steep low-frequency attenuation to improve sound pickup without affecting voice quality
  • Accepts interchangeable elements to permit angle of acceptance from 90° to 360°
  • Low-profile design with low-reflectance finish for minimum visibility
  • Available in two colors: black (U853R) and white (U853RW)
