Shure's PSM 900 Wireless Personal Monitor System is an industry standard for a reason. With patented Audio Reference Companding, exceptional transmitter linearity, and patented CueMode functionality, PSM 900 meets the needs of professional audio applications of all kinds, providing excellent audio quality and reliable RF performance. With 20 compatible frequencies per band and a 36 MHz to 40 MHz tuning bandwidth, the PSM 900 system has the horsepower to handle demanding environments, including professional IEM and IFB applications.

Unparalleled Audio Quality:
- Bodypack receivers with advanced digital signal processing technology deliver more headroom, improved stereo separation, and higher audio fidelity
- Patented Audio Reference Companding offers natural and transparent sound
- Available with Shure SE425 Sound Isolating earphones featuring dual high-definition MicroDrivers for accurate and balanced audio response

Robust RF Performance:
- P9RA+ bodypack receivers offer enhanced signal reception and range
- Precision front-end RF filtering significantly reduces RF interference for a cleaner, stronger RF signal, fewer dropouts, and fewer audible artifacts
- Exceptional transmitter linearity vastly reduces frequency intermodulation and allows up to 20 compatible channels per frequency range
- Automatic RF gain control prevents signal distortion due to RF overload before it can affect performance

Category-Leading Setup and Operation Features:
- CueMode allows monitoring of different stage mixes and storing of up to 20 separate channels on one bodypack for quick and easy reference
- Front panel RF mute switch enables or disables RF transmission during setup
- Scan and Sync scans the RF environment with the bodypack and assigns an identified group and channel to your system over wireless IR link
- MixMode technology combines two separate audio channels for simultaneous listening in both ears, or can transmit two independent IFB program feeds
- Four-band parametric EQ gives you the choice to adjust frequencies for a fully customized sound
- Input EQ Presets gives you the option to further tailor your sound, including the option to make the P9RA+ sound like the P9RA with a designated "Match" setting

Advanced Rechargeability Options:
- The SB900A lithium-ion rechargeable battery provides extended usage times and precise tracking of remaining life and charge cycle details
- The SCB800-US eight-bay charger brings up to eight SB900 batteries to full charge within two hours and has charge status LEDs for each battery
- The SBC200 dual-docking charger works with SB900A, P9RA+, P10R+, QLXD Digital Wireless Systems, and ULX-D Digital Wireless Systems, available with and without power supply
- The SBC220 networked dual-docking charger works with SB900A, PSM 900 (P9RA+ only), PSM 1000 (P10R+ only), QLX-D Digital Wireless Systems, ULX-D
Digital Wireless Systems, and Axient Digital (AD1 and AD2 only), available with and without power supply. When the SBC220 is connected to a network, battery information for each transmitter can be viewed remotely.
