Shure P9TRA+425CL – PSM900 Wireless In-Ear Monitor System

Product Overview

The Shure P9TRA+425CL is a complete PSM 900 Wireless Personal Monitor System combining the P9T half-rack wireless transmitter, the P9RA rechargeable bodypack receiver, and SE425 Sound Isolating earphones in a single package. Designed for commercial live sound, house of worship, broadcast, and touring applications, this PSM900 wireless IEM system delivers professional-grade in-ear monitoring with transparent audio, reliable RF performance, and the comfort of dual-driver earphones. Available in multiple frequency bands (G6, G7, H21, L6), it provides a complete turn-key solution for performers requiring in-ear monitoring.

Product Description

The P9T transmitter anchors the system from the rack with balanced XLR and 1/4" inputs, CueMode for private engineer-to-performer communication, and Scan and Sync for rapid frequency coordination. The P9RA rechargeable bodypack receiver enables performers to work without disposable batteries, with a rechargeable lithium-ion battery for extended run times. The SE425 Sound Isolating earphones provide up to 37 dB of ambient noise isolation through dual high-definition drivers—a dedicated tweeter and woofer—delivering detailed, balanced sound for in-ear monitoring. A detachable cable with MMCX connector and 360-degree rotation ensures a secure fit regardless of the performance environment. For the standalone transmitter, see the Shure P9T Wireless Transmitter.

Frequently Asked Questions

What is included in the P9TRA+425CL system?
The system includes three components: the P9T half-rack wireless transmitter, the P9RA rechargeable wireless bodypack receiver, and the SE425 Sound Isolating earphones with detachable cable.

Can I add additional receivers to expand the system?
Yes. Additional P9RA or P9RA+ receivers can be paired with the P9T transmitter in a broadcast/multi-receiver configuration, provided they operate on the same frequency band. Frequency coordination should be managed using Shure Wireless Workbench.

Do the SE425 earphones detach from the bodypack?
The SE425 earphones connect to the P9RA receiver via a standard cable; they are not permanently attached. The earphones use an MMCX connector with a lock-snap mechanism for secure attachment and easy swapping.

What inputs does the P9T transmitter accept?
The P9T accepts balanced XLR and 1/4" line-level inputs from a mixing console aux send or monitor matrix output, with a loop output for daisy-chain connections.

Is this system suitable for permanent fixed installation?
Yes. The P9T transmitter can be permanently rack-mounted and the system is equally appropriate for fixed-installation environments such as houses of worship, broadcast studios, and conference auditoriums, as it is for touring productions.
