Shure PA421BX Four-channel Antenna Combiner, 865-960 MHz

Shure PA421BX Four-channel Antenna Combiner, 865-960 MHz 

The PA421BX Antenna Combiner designed by Shure combines up to four PSM transmitters to a single antenna set. The PA421BX can be used when multiple wireless systems are required for monitoring in sound reinforcement applications.

The PA421BX decreases rack clutter, optimizes RF management, and helps in providing DC power to compatible IEM transmitters. LED indicators for signal presence and signal overload provide four input LED signals (green when active, off inactive). Also, it is embedded with a very quiet, temperature-sensitive fan that keeps the unit cool.
