RELACART | UB-200 | UB-200 Semi-Cardioid Condenser Wireless Boundary Microphone

UB-200 Semi-Cardioid Condenser Wireless Boundary Microphone



Key Features:
  • UHF band 490 – 860MHz wireless boundary microphone.
  • Bright and easy-to-read LCD display shows operating channel / frequency, battery level, mute and other working status.
  • Semi-cardioid polar pattern.
  • Ultra-quiet electronic switch can be set to any of four operating modes: "touch - mute”, “touch - on”, "touch-to-talk" and "touch-to-mute" (only cooperates with wireless receiver UR-220D & UR-220S).
  • RFI-shielding technology offers rejection of radio frequency interference (RFI).
  • Available interchangeable elements permit angle of acceptance from 120°to 360°.
  • The microphone switch can control or be controlled by external automatic central control system or other devices.
  • Superior off-axis rejection for maximum gain before feedback.
  • Heavy die-cast case and non-slip silicon foam bottom pads minimize coupling of surface vibration to the microphone.
  • Battery operation of max. 10 hours.
  • Designed for surface-mount applications such as high-quality sound reinforcement, professional recording, television, conferencing and other demanding sound pickup situations.
  • UB-200 can cooperate with RELACART digital and wireless automatic mixer WAM-400, wireless receiver UR-220D or UR-220S.
