Shure PSM300 TwinPack Pro Description

The Shure PSM300 TwinPack Pro provides professional wireless monitoring for two performers using a single P3T stereo transmitter and two P3RA bodypack receivers. Designed for live sound environments, the system delivers detailed 24-bit digital audio processing with Shure's patented Audio Reference Companding technology for clear sound reproduction and reduced background noise. The G20 configuration operates within the 488-512MHz UHF frequency range with up to 24MHz tuning bandwidth and 15 compatible frequencies. Its wireless operating range of up to 300 feet (90 meters) allows musicians and performers to move freely around the stage while maintaining their personal monitoring connection.

Each included P3RA bodypack receiver provides independent listening controls through Shure MixMode technology. With MixMode, two incoming audio channels can carry different monitor mixes, such as vocals and instruments, allowing each performer to adjust their preferred balance. Stereo mode provides conventional left/right monitoring with adjustable channel balance. Both receivers receive the same two transmitted channels, but each performer can customize the blend and overall headphone volume independently. The P3RA also features a two-band shelving EQ for bass and treble adjustments, an adjustable volume limiter, a high-contrast LCD display, and durable all-metal construction. Automatic frequency scanning and one-touch infrared synchronization simplify setup and wireless frequency coordination.

The PSM300 TwinPack Pro includes two pairs of Shure SE215 Sound Isolating Earphones, providing detailed personal monitoring with enhanced bass response and comfortable in-ear fit. Each earphone uses a single dynamic MicroDriver with a frequency response of 22Hz-17.5kHz and a sound-isolating design that reduces surrounding noise by up to 37dB when properly fitted. Detachable cables with MMCX connectors provide a secure connection and allow 360-degree rotation for comfortable positioning. Multiple ear sleeve sizes are included to help performers achieve a secure fit and consistent acoustic isolation during extended rehearsals and live performances.

The included P3T wireless transmitter features a rugged half-rack metal chassis with two balanced 1/4-inch TRS audio inputs and corresponding loop outputs for flexible integration with mixing consoles and monitor systems. Selectable Line and Aux input sensitivity accommodates professional audio mixers and consumer-level devices. Its front-panel LCD provides left and right audio metering, frequency information, and system settings, while a detachable quarter-wave antenna supports wireless transmission. The transmitter operates from an external power supply and provides up to 30mW RF output power in the G20 frequency band. The included rackmount hardware allows convenient installation in professional audio racks and touring systems.

Built for professional live sound applications, the PSM300 TwinPack Pro includes the essential components for two-performer wireless monitoring, including two P3RA bodypacks, two SE215 earphone sets, transmitter accessories, AA batteries, and protective storage bags. Each P3RA bodypack operates using two AA batteries and is compatible with optional Shure rechargeable lithium-ion batteries for convenient long-term use. With its detailed audio processing, personal mix controls, reliable UHF transmission, and professional construction, the PSM300 TwinPack Pro is suited for touring musicians, vocalists, bands, church worship teams, theater productions, and event sound systems.
