Shure P3TR PSM 300 Wireless In-Ear Monitoring System
The Shure P3TR PSM 300 Wireless In-Ear Monitoring System is a half-rack 24-bit digital audio wireless transmitter for the personal in ear monitoring system. It can be used in various environments to send 2 channels of audio to a bodypack receiver (sold separately), up to 300′ away for applications such as live stage, theatre, rehearsals, and more. It features audio reference companding to ensure transparent sound quality with no artefacts or dropouts. This rugged transmitter is built with easy front-panel controls, including the one-touch sync and input level knobs which are there to enable quick setup and easy operation. Furthermore, the rear-panel has balanced inputs and loop outputs that can provide versatile connectivity to other audio sources or other P3T units.
Key Features:
- Up to 30mW output power (region dependant)
- 1/4″ (6.3mm) TRS balanced inputs and loop outputs
- 24 MHz tuning range (region dependant)
- High-contrast LCD menu with detailed L/R audio output metres
- Detachable 1/4 wave antenna
- External power supply
- Selectable line/aux level
