Used Shure PSM900

The Shure PSM900 is a professional wireless in-ear monitor system built around P9T transmitters and P9RA receivers. It is used in live performance, studio recording and broadcasting, and scales across multi-channel configurations to suit sound engineers and musicians who need reliable wireless monitoring across multiple performers or sources simultaneously.

The PSM900 is available in more than one frequency band. Units have been supplied operating in the 470-506 MHz range and in the 702-742 MHz range. Buyers should confirm which band a specific unit covers before purchasing, as frequency availability varies by region and regulatory environment.

The PA821A combiner antenna is designed specifically for the PSM900 and is used to combine multiple transmitter outputs into a shared antenna system. The PA805WB directional antenna is also used alongside the system to extend signal strength and range, making both accessories relevant for larger multi-channel deployments at live events or in broadcast environments.

The PSM900 is made by Shure, an American audio manufacturer with roots in wired and wireless microphones and in-ear monitoring for live performance, broadcast and installation. The PSM900 sits within Shure's professional wireless in-ear monitor line, targeting sound engineers and performing musicians who require scalable, multi-channel wireless monitoring solutions.
