The white version of U853RU, the U853RWU UniLine condenser hanging microphone features Audio-Technica’s UniLine™ line-cardioid element and is equipped with UniGuard™ innovations that offer unsurpassed immunity from radio frequency interference. The phantom-powered microphone accepts interchangeable elements, available in cardioid, hypercardioid, omnidirectional and UniLine™ line cardioid polar patterns. Its 80 Hz low-cut UniSteep® filter reduces pickup of low-frequency ambient noise.

• Designed for suspension over choirs, instrumental groups and theater stages
  
• UniLine™ polar pattern provides narrow 90° acceptance angle
  
• 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 (U853RU) and white (U853RWU)
