{"product_id":"shure-psm900-system-p9tra-425cl","title":"Shure PSM900 – Wireless In-Ear Monitor System, H21 542–578 MHz","description":"\u003ch2\u003eProduct Overview\u003c\/h2\u003e\n\u003cp\u003eThe Shure PSM900 wireless in-ear monitor system is built for sound engineers and AV integrators who need dependable, high-fidelity wireless personal monitoring in demanding production environments. This configuration (P9TRA425CL) pairs the P9T half-rack wireless transmitter with the P9RA+ bodypack receiver and Shure SE425-CL sound isolating earphones, operating in the H21 band (542–578 MHz). It is a strong fit for wireless personal monitor system integration in broadcast studios, houses of worship, and auditoriums where RF reliability and audio clarity both matter. Integrators specifying a commercial wireless IEM system installation get rack-mount transmission, digital-stereo receiver architecture, and professional earphones in one verified frequency-band package.\u003c\/p\u003e\n\u003ch2\u003eProduct Description\u003c\/h2\u003e\n\u003cp\u003eThe PSM900 system uses Shure's patented Audio Reference Companding and precision front-end RF filtering to deliver clean, consistent in-ear monitoring even in RF-dense venues. The P9T transmitter is a half-rack, single-channel unit with front or rear antenna mounting, making it straightforward to integrate into an existing rack-mount wireless bodypack transmitter receiver system alongside other RF gear. The P9RA+ bodypack receiver uses a hybrid analog\/digital architecture for improved headroom and stereo separation, and its CueMode feature lets performers or presenters switch between multiple stored monitor mixes from the bodypack itself. Scan and Sync IR linking allows the bodypack to scan the local RF environment and auto-sync group and channel settings from the transmitter, which speeds up setup on multi-channel systems. A front-panel RF mute switch and auto RF gain control add operational safeguards for live events where dropouts or overload are not an option.\u003c\/p\u003e\n\u003cp\u003eThis specific unit is tuned to the H21 band (542–578 MHz), a UHF wireless in-ear monitor frequency range that AV designers should confirm against local spectrum coordination before deployment, particularly when running multiple wireless systems in the same venue. Paired SE425-CL earphones use dual high-definition drivers and a Sound Isolating design rated to block up to 37 dB of ambient noise, with a detachable cable and a fit kit of sleeve options for long-wearing comfort during extended sessions. Together, the transmitter, receiver, and earphones form a complete in-ear monitoring system for houses of worship, broadcast studios, and other commercial-grade production environments where performers, presenters, or on-air talent need a dedicated, interference-resistant monitor mix.\u003c\/p\u003e\n\u003ch2\u003eKey

Questions\u003c\/h2\u003e\n\u003ch3\u003eIs the SE425-CL earphone connector compatible with other Shure wireless bodypack receivers?\u003c\/h3\u003e\n\u003cp\u003eYes. The SE425-CL uses a detachable, gold-plated cable that connects to the bodypack's 3.5 mm output, so the earphones can be used with other Shure wireless personal monitor receivers if a compatible cable is used.\u003c\/p\u003e\n\u003ch3\u003eWill the H21 band (542–578 MHz) work in my region?\u003c\/h3\u003e\n\u003cp\u003eH21 is one of several regional frequency bands Shure offers for the PSM900. Confirm local spectrum availability and coordination requirements with your AV system designer or RF coordinator before specifying this band for a commercial deployment, especially in markets with TV band or licensed spectrum restrictions.\u003c\/p\u003e\n\u003ch3\u003eCan this system be rack-mounted with other wireless AV equipment?\u003c\/h3\u003e\n\u003cp\u003eYes. The P9T is a half-rack, single-channel transmitter designed for standard AV racks. Two units can typically be mounted side by side with an appropriate rack tray, and front or rear antenna connections support flexible RF distribution setups.\u003c\/p\u003e\n\u003ch3\u003eHow many channels can I run simultaneously in the same venue?\u003c\/h3\u003e\n\u003cp\u003eThe PSM900 supports up to 20 compatible frequencies per band within its tuning bandwidth. Actual channel counts depend on RF coordination, antenna distribution, and other wireless systems operating in the same space, so a site-specific frequency plan is recommended for multi-channel commercial deployments.\u003c\/p\u003e\n\u003ch3\u003eWhat is covered under warranty and how do I get support?\u003c\/h3\u003e\n\u003cp\u003eShure backs the PSM900 system and SE425-CL earphones with a manufacturer's warranty covering defects in materials and workmanship. Creation Networks can help coordinate warranty service and provide pre- and post-installation support for AV integrators and end users.\u003c\/p\u003e\n\u003ch3\u003eDoes this system require an external antenna or combiner for larger installations?\u003c\/h3\u003e\n\u003cp\u003eNot for a single-channel setup, but larger commercial deployments running multiple PSM900 transmitters typically benefit from an antenna combiner and distribution antennas to reduce RF clutter and simplify cabling. Contact Creation Networks for guidance on scaling a multi-channel wireless monitoring rig.\u003c\/p\u003e\n\u003ch3\u003eCan I integrate this with an existing house of worship or broadcast studio audio system?\u003c\/h3\u003e\n\u003cp\u003eYes. The P9T transmitter accepts standard balanced line-level or mic-level input via XLR\/TRS combo connectors, allowing it to tap directly into an existing mixing console or broadcast audio chain without additional signal conversion hardware.\u003c\/p\u003e","brand":"Shure","offers":[{"title":"Default Title","offer_id":46792779006188,"sku":null,"price":1729.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0603\/7982\/4364\/files\/CN_PSM900.jpg?v=1759139414","url":"https:\/\/creationnetworks.net\/products\/shure-psm900-system-p9tra-425cl","provider":"Creation Networks","version":"1.0","type":"link"}
