Shure PA421B Four-channel Antenna Combiner, 470-865 MHz

Shure PA421B Four-channel Antenna Combiner, 470-865 MHz

The PA421B Antenna Combiner designed by Shure combines up to four PSM transmitters to a single antenna set. The PA421B can be used when multiple wireless systems are required for monitoring in sound reinforcement applications.

The PA421B 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.
