UR-222S Antenna Diversity wireless mic system


The UR-222S series antenna diversity wireless mic system is popular audio equipment due to its sophisticated appearance, stable performance, convenient operation, and attractive price. This series is suitable for places with specific requirements like nigh clubs, multi-function spaces, hotels, conference rooms, and small to medium music venues.

Key features:
  • Antenna diversity uses two or more antennas to improve the quality and reliability of the wireless signal.
  • The main frame adopts EIA standard ½ U metals, has compact structure and light weight.
  • Super wide frequency range of UHF554MHz~936 MHz supports automatic frequency selection and CPU intelligent antenna diversity receiving.
  • The new optimized circuit design allows better sound quality as well as more stable and further transmission distance.
  • Precise low-power circuit design; uses two AA alkaline batteries but twice battery life as common mices.
  • UR-222S can match UH-222 handheld microphone and UT-222 bodypack transmitter.
  • UHF Wireless Receiver
  • Vocal Microphone
