Shure PA411 | 4-Input PSM300 Antenna Combiner
$866.00
Shure PA411 combines the RF outputs and distributes DC power for up to four Shure PSM300 transmitters. Its compact half-rack design allows multiple personal monitor transmitters to share one antenna while reducing the number of individual power supplies and antennas required in a rack.
The Shure PA411 is designed to simplify wireless in-ear monitor systems that use multiple PSM300 transmitters. Instead of placing a separate antenna and power supply on every transmitter, the PA411 consolidates up to four RF signals and routes them through one antenna output.
Four RF inputs allow compatible P3T transmitters to connect to the combiner, while four DC outputs distribute power to those transmitters. This centralized arrangement creates a cleaner rack, reduces the number of required connections, and makes multi-channel monitor systems easier to install and manage.
Front-panel indicators display RF signal presence and warn of input overload on each channel. The wideband RF architecture covers 470–865 MHz, allowing the unit to work across compatible PSM300 operating bands without requiring a band-specific combiner.
Its rugged half-rack enclosure is suited to touring racks, houses of worship, theaters, production companies, venues, and installed sound systems using up to four Shure PSM300 transmitters.
