Shure PGXD14/PGA31 Digital Wireless Cardioid Headset Microphone System (900 MHz)


The Shure PGXD14/PGA31 is a wireless headset microphone system offering high-quality 24-bit / 48 kHz digital audio in a cost-effective, reliable package that's easy to use. The lightweight tabletop receiver is highly portable, making it an excellent fit for on-the-go presenters, lecturers, fitness instructors, performers, and DJs working in small venues—including weddings, houses of worship, classrooms, offices, and conference spaces.

PGX-D Digital systems operate in the 900 MHz band, far away from potential TV and cell phone interference. The receiver offers true digital diversity, using two antennas and two independent receiver circuits to ensure reliable transmission at a maximum line-of-sight range of up to 200'.

Operation is simple. Press the Scan button, and the receiver scans for a clean frequency. Press the Sync button, and the receiver and transmitter lock to the same channel via infrared ports. That's it, you're up and running. If the RF environment changes and interference is heard, simply rescan and resync to operate on a new clean frequency.

This configuration comes with a PGA31 headset condenser mic and a bodypack transmitter that will run for up to 10 hours on two AA batteries. Up to 5 wireless mics can operate simultaneously in the same space.
