Description
The Shure PA411 Antenna Combiner distributes DC power and RF signal for up to four Shure PSM®300 transmitters. The compact half-rack system significantly reduces the number of antennas and power supplies needed when using multiple systems.
Features:
- Main RF output connector connects to any antenna with a BNC connector
- RF LED indicators display signal present and signal overload per input
- Power output distributes DC power to PSM transmitters (accessory power cable required)
- Features a front panel power switch
