UR-223S UHF True Diversity wireless mic system

UR-223S UHF True Diversity wireless mic system

The UR-223Sseries wireless mic system adopts a true diversity receiving method to ensure stable performance, convenient operation and superior professional quality. This series is suitable for applications with higher sound requirements such as night clubs, multi-function rooms, conference rooms, medium or large-scaled performance stages and more.

Key features:
  • The main frame adopts EIA standard ½ U metals.
  • The receiver is equipped with an LCD display and shows working channel/frequency, RF/AF, transmitter battery level, etc.
  • Super wide frequency range of 554MHz~936 MHz, intelligent antenna diversity and automatic connection.
  • PLL (phase lock loop frequency control) design can effectively block noise and radio frequency interference in the working environment.
  • The receiver has bandwidth of 32MHz, and you are allowed to use maximum of 10 sets of mic systems within the range of 32MHz.
  • The transmitter has bandwidth of 134MHz which allows simpler adjustment.
  • The capsule of the handheld microphone is detachable; you can choose either dynamic or condenser capsule, or even using global well-known brand microphone capsule.
  • Precise low-consumption circuit design; uses two alkaline batteries but has twice the battery life as common mics.
  • UR-223S system can cooperate with UH-222 handheld microphone and UH-222 bodypack transmitter.
