Wireless Microphones, Expanded!

Shure's UA844+SWB is a wideband UHF five-way active antenna splitter and power distribution system that allows for the expansion of wireless microphone systems by splitting one pair of antennas to multiple receivers. This unit amplifies RF signals for insertion loss that results from splitting signal power to multiple outputs, meaning you won't have to worry about dropouts when connected to this system.


  • Five-way RF signal output
  • Supports QLX-D, ULX, ULX-D, SLX, and BLX (BLX4R only) receivers
  • Front-mounting antenna hardware
  • Rackmounting hardware
  • Four DC power feeds for receivers (15 V, 2.5 A max)
  • DC outputs for antenna bias (12 V, 300 mA max)
