The PSM 900 Wireless Personal Monitor System from Shure is a professional-quality wireless monitoring system that provides high-quality audio and RF performance in a compact and durable design. The kit includes a P9T half-rack transmitter, a P9RA+ bodypack receiver, and a pair of SE425-CL clear in-ear monitors.

The system features an operating distance of 300' and a tuning bandwidth of 36 to 46 MHz. The digital stereo encoder offers audio detail and clarity and a patented Audio Reference Companding that sounds more like wired audio than other competing wireless systems. A rackmount kit is included along with a power supply.

The P9RA+ Wireless Bodypack Receiver from Shure is an updated version of the P9RA low profile, diversity stereo bodypack receiver for the PSM 900 wireless personal monitor system (sold separately). The receiver has a slim and compact extruded aluminum construction for easy placement on a performer. It offers improvements like more headroom, better stereo separation, and higher fidelity for robust RF performance and a cleaner, stronger signal with fewer dropouts and artifacts. With touring-grade features like full-bandwidth RF scanning, front-end RF filtering, and automatic RF gain control, the P9RA+ meets the needs of professional audio application of all sizes, including IEM and IFB applications.

The receiver syncs easily to a P10T transmitter over an IR link using the built-in Scan and Sync function. Volume and balance controls are provided for easy customization. A selectable 4-band parametric EQ is also provided. Shure's CueMode allows you to monitor different stage mixes, as well as store up to 20 different channels on a single bodypack. The receiver also includes audio and RF status LEDs, as well as audio level and battery life metering. The P9RA+ operates on a pair of standard AA batteries for 4-6 hours of continuous use, and it can also be used with Shure Li-ion rechargeable batteries for extended life. The P9RA+ has a standard 3.5mm headphone jack and is compatible with all Shure SCL sound-isolating earphones, which are designed specifically for use with PSM systems.
