Shure P3TR112TW PSM 300 Twin Pack Wireless In-Ear Monitor System

The Shure P3TR112TW PSM 300 Twin Pack is a complete wireless in-ear monitoring system designed for two performers who want clear, dependable personal monitoring onstage. Combining one P3T wireless transmitter, two P3R bodypack receivers, and two pairs of SE112 Sound Isolating earphones, this package provides a convenient solution for musicians, vocalists, worship teams, and live production professionals.

The PSM 300 system delivers 24-bit digital audio processing, wireless operation up to 300 feet (90 meters) under suitable conditions, and Shure's patented Audio Reference Companding technology for clear, low-noise monitoring.

Each performer can independently adjust their listening volume and use Shure MixMode technology to balance two audio channels transmitted by the P3T. This allows both users to customize their monitoring experience while sharing a single wireless transmitter.

Complete Wireless Monitoring for Two Performers

The P3TR112TW includes the essential components needed to establish a two-person wireless monitoring system.

A single P3T transmitter receives audio from a mixing console and sends the signal wirelessly to two P3R bodypack receivers operating on the same frequency.

Each performer connects their included SE112 earphones to their bodypack and adjusts the listening level independently.

This arrangement reduces the need for conventional floor monitor speakers and allows performers to move freely around the stage.

It is especially useful for acoustic duos, vocalists, worship musicians, and small performance groups.

Shure MixMode Personal Monitoring

The PSM 300 system supports stereo monitoring and Shure's MixMode technology.

In stereo mode, performers hear the left and right channels as a conventional stereo signal.

In MixMode, each P3R receiver combines the two transmitted channels into a mono listening mix. Each performer can adjust the balance between those channels independently.

For example, one channel could carry a vocal-focused mix while the other carries the rest of the band. Each performer can then adjust the balance to suit their needs.

Both receivers share the same two transmitted audio channels, but each user can control their own listening balance and volume.

Clear 24-Bit Digital Audio

The PSM 300 system uses 24-bit digital audio processing and Shure Audio Reference Companding to deliver detailed monitoring with low background noise.

With more than 90 dB of dynamic range, performers can hear vocals, instruments, and musical cues clearly.

The system supports both mono and stereo monitoring configurations, making it adaptable to different mixing consoles and stage requirements.

Clear personal monitoring can help musicians maintain timing and pitch while reducing their dependence on loud floor wedges.

Easy Wireless Setup and IR Synchronization

The P3T transmitter and P3R receivers are designed for straightforward frequency selection and synchronization.

One-touch frequency scanning helps identify an available wireless channel, while infrared synchronization transfers the selected settings between the transmitter and receivers.

The transmitter features a front-panel LCD with audio metering and operating information.

Once both bodypacks are synchronized to the transmitter, the two performers can receive the same wireless audio transmission.

Actual operating range depends on RF conditions, obstructions, antenna placement, and local wireless activity.

Two P3R Wireless Bodypack Receivers

Each included P3R receiver provides convenient controls for personal monitoring.

The compact bodypack features a headphone output, volume adjustment, MixMode and stereo operation, and a battery status indicator.

Each receiver operates on two AA batteries and provides up to approximately six hours of operation, depending on battery condition and operating conditions.

The lightweight design allows performers to attach the receiver to a belt or instrument strap for comfortable use during rehearsals and performances.

SE112 Sound Isolating Earphones

The P3TR112TW includes two pairs of Shure SE112 Sound Isolating earphones.

Each pair uses a single dynamic driver to reproduce vocals and instruments with clear, balanced sound.

The sound-isolating design can reduce ambient noise by up to 37 dB when properly fitted, helping performers hear their monitoring mix without excessive volume.

Multiple earphone sleeve sizes are included to accommodate different ear shapes and improve comfort and isolation.

Professional P3T Wireless Transmitter

The included P3T transmitter features a rugged metal chassis suitable for professional stage installations.

Two balanced 1/4-inch TRS inputs accept audio from compatible mixing consoles, while corresponding loop outputs allow signals to be passed to additional equipment.

Selectable line and auxiliary input sensitivity provides flexibility when connecting different audio sources.

The detachable antenna and included rackmount hardware support installation in portable or permanent sound systems.

Recommended Applications

The Shure P3TR112TW is suitable for professional monitoring applications including:

• Live bands and acoustic duos
• Vocalists and instrumental performers
• Houses of worship and worship teams
• Theater and musical productions
• Touring and mobile performance systems
• Rehearsal studios
• School and community performances
• Small to medium-sized live stages

System Compatibility and Setup

The P3TR112TW connects to compatible mixing consoles through the balanced audio inputs on the P3T transmitter.

Both included P3R receivers must operate within the transmitter's matching frequency band.

The system transmits two audio channels, allowing each performer to use stereo monitoring or create an individual mono balance through MixMode.

Additional compatible receivers may be used with the same transmitter when operating on the same frequency and receiving the same transmitted audio channels.

For independent audio programs beyond the two transmitted channels, additional transmitter channels or separate wireless monitoring systems are required.
