SHURE P9RAPLUS-L6E

Shure PSM 900 Wireless In-Ear Monitor System (P9RA+ Receiver) Premium audio quality thanks to the P9RA+ receiver with hybrid analog/digital architecture, offering greater dynamics, improved stereo separation, and high fidelity. Robust RF for challenging stage environments: up to 20 compatible frequencies per band, highly efficient RF filters, automatic RF gain control, and extended range. Professional tools for touring and broadcast: ultra-fast frequency scanner, bidirectional infrared sync, Cue Mode, RF Mute, MixMode. Comfort and listening safety: semi-parametric equalizer, adjustable limiter, and V-Lock function to lock volume at the receiver level. PSM 900: a third generation designed for modern RF environments With this third generation, the PSM 900 establishes itself as a wireless personal monitoring solution designed for demanding professional audio applications. Its operation is optimized for high RF density contexts, featuring an RF switching range of 36 MHz and functionalities aimed at maintaining stable and reliable transmission on complex stages. The P9RA+ marks a major evolution in the PSM900 range by combining digital signal processing and hybrid architecture to deliver more precise and controllable listening. Who is the Shure PSM 900 (P9RA+) intended for and in which applications? The Shure PSM 900 (with P9RA+ receiver) is primarily aimed at touring and broadcast professionals, as well as live performances where RF stability and in-ear mix consistency are non-negotiable. It suits musicians, vocalists, monitor technicians, and sound engineers who need to manage multiple mixes and quickly verify reception quality on stage. Thanks to Cue Mode, the engineer can control each musician's mix and monitor RF transmission quality without disrupting the show flow. For setups requiring direct control on the unit, MixMode enables bi-mono listening with mixing via the receiver's balance control, convenient for managing two sources (e.g., vocals and band) without multiplying sends. Performance, control, and innovations of the P9RA+ receiver RF: stability, dropout resistance, and easier coexistence The PSM 900 emphasizes reliability in crowded environments: high-performance RF filters to reduce interference, automatic RF gain control to limit intermodulation, and a transmission that is advertised as more robust with improved dropout resistance and extended range. The inclusion of an ultra-fast frequency scanner helps quickly find a clean and usable channel. Audio: Shure companding and onboard digital processing The P9RA+ receiver incorporates digital signal processing aimed at delivering more detailed reproduction, with increased dynamics and superior stereo separation. The system also relies on Shure's patented "Audio Reference Companding" designed to preserve musicality and signal coherence in a wireless transmission context. Equalization, limiter, and volume locking: a safer, more controlled in-ear experience To tailor the sound signature to the musician and earphone type, the P9RA+ offers a 4-band semi-parametric equalizer and a Match preset designed to replicate the original P9RA sound. For safety, the headphone amplifier limiter better controls peaks, and the V-Lock function locks the volume setting to prevent accidental changes during performance. The receiver also supports lower impedance earphones (down to 4 ohms), opening the door to a wide range of professional in-ear monitors while maintaining precise level control. Workflow: synchronization, control, and implementation without disrupting the stage The bidirectional infrared sync facilitates programming between transmitter and receiver, while the RF Mute function allows preparation or modification of a setup without disturbing other nearby wireless systems. The LCD screens on both transmitter and receiver display detailed audio and RF parameters, speeding up diagnostics and securing operation in real conditions. A standby function is also featured on the P9RA+ to optimize long-term use.
