Shure PA411 Four Port Antenna Combiner

Product Overview

The Shure PA411 is a four-port antenna combiner that consolidates RF signal and DC power for up to four Shure PSM300 wireless transmitters. It is the standard RF distribution accessory for multi-system PSM300 in-ear monitoring deployments, reducing antenna and power-supply clutter in racks. AV integrators use it to clean up RF management when running several P3T transmitters in the same venue. The compact half-rack form factor fits neatly into commercial monitoring racks.

Product Description

When a venue runs more than one PSM300 system, each transmitter would otherwise need its own antenna and power supply, crowding the rack and complicating RF coordination. The PA411 antenna combiner solves this by distributing a single antenna feed and DC power across up to four P3T transmitters from one half-rack unit. This simplifies installation, reduces cabling, and supports cleaner RF management in fixed installs and touring racks. It is well suited to houses of worship, auditoriums, and broadcast facilities deploying multiple channels of wireless in-ear monitoring. As a genuine Shure accessory, it is engineered specifically for PSM300 transmitter compatibility.
