Shure PSM 300 Twin-Pack Wireless In-Ear Monitor Kit (G20: 488 to 512 MHz)

The Shure P3TR112TW-G20 is a complete wireless in-ear monitor kit built for performers who need clear, dependable audio on stage. It pairs a P3T transmitter with two P3R bodypack receivers and a set of SE112 sound-isolating earphones, giving two musicians their own mixes without sharing wedges or fighting stage noise.

Audio is delivered in 24-bit digital quality across the G20 frequency range of 488 to 512 MHz, and the signal can travel up to 300 feet, which suits everything from small clubs to midsize outdoor stages. A single button scans the airwaves, finds an open channel, and syncs the transmitter with both receivers, so setup stays fast even in hectic changeovers. Once connected, each user can choose MixMode to blend two sources or select standard stereo monitoring for a traditional left-right image, then adjust volume to taste on the lightweight belt-packs.

For vocalists, guitarists, drummers, or theater actors who move around the stage, the included SE112 earphones block up to 37 dB of ambient sound, letting the performance stay focused and consistent regardless of venue acoustics. The earphones sit low in the ear, and the reinforced cable routes over the ear to keep them secure during energetic sets.

Everything required to start monitoring ships in the box, including quarter-wave antennas, a power supply, AA batteries for immediate use, and zippered pouches that protect the gear between shows. The result is a portable, road-ready system that lets two performers step on stage with confidence and hear exactly what the audience hears.
