Audio-Technica U891Rb Cardioid Condenser Boundary Mic with Switch RGB LED & Integral Power Module - Phantom Power Only

U891RB - Overview

• Features:

  • Cardioid condenser boundary microphone with touch-sensitive capacitive-type user switch
  • Designed for surface-mount applications such as high-quality sound reinforcement, professional recording, television, conferencing and other demanding sound pickup situations
  • The capacitive touch switch can be set to any of three operating modes: touch on/off, touch to talk and touch to mute
  • Integral, phantom-powered, two-state RGB LED indicator displays on/off status of microphone
  • Superior off-axis rejection for maximum gain before feedback
  • PivotPoint® rotating output connector allows cable to exit from either the rear or the bottom of the microphone
  • Small-diameter UniPoint® element near boundary eliminates phase distortion and delivers clear, high-output performance
  • Available interchangeable elements permit angle of acceptance from 100° to 360°
  • UniGuard® RFI-shielding technology offers outstanding rejection of radio frequency interference (RFI)
  • Self-contained electronics eliminate need for external power module
  • Heavy die-cast case and non-slip silicone foam bottom pads minimize coupling of surface vibration to the microphone
  • Low-profile design with low-reflectance finish for minimum visibility
  • Threaded inserts on bottom of microphone allow it to be mounted with screws for increased security
