Shure PA411 Four Port Antenna Combiner

Shure PA411 Four Port Antenna Combiner

The PA411 designed by Shure is a wideband antenna combiner that distributes DC power and RF signal for up to four Shure PSM300 transmitters which are sold separately. The PA411 also features a compact half-rack system that is being used to reduce the amount of antennas and power supplies required when using multiple systems in application such as for live stage, theater, rehearsals, and more. It is featured with a RF LED indicator display to signal the presence of a signal and a signal overload. It is also built with a front panel power switch. The PA411 included are rack-ears, 1/4 wave antenna, BNC bulkhead adapter, BNC cable and power supply.
