Shure BETA 57A
Supercardioid dynamic microphone

The Shure PGXD24/SM86 is a wireless handheld 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, 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 handheld transmitter featuring an interchangeable SM86 condenser mic capsule with a cardioid pickup pattern. The transmitter runs for up to 9 hours on two AA batteries. Up to 5 wireless mics can operate simultaneously in the same space.
