Shure QLXD4

The QLXD4 is the half-rack single-channel receiver at the center of a QLX-D digital wireless system, delivering transparent 24-bit audio to a mixer from a QLXD1 bodypack or QLXD2 handheld transmitter. Automatic channel scan finds the cleanest open frequency, and one-touch IR sync pushes it to the transmitter, so setup takes seconds rather than a manual frequency hunt. Digital predictive switching diversity keeps the RF link solid, and AES-256 encryption secures the audio.

Ethernet networking lets multiple receivers scan and coordinate frequencies together and connect to Shure Wireless Workbench, with monitoring and control from an iOS device via the ShurePlus Channels app. The brushed-aluminum front panel carries a high-contrast LCD with a lockout, and the back panel offers a mic/line switchable XLR output plus a 1/4-inch instrument output, detachable half-wave antennas on BNC, and up to 60 dB of adjustable gain. It ships with the rackmount kit and external power supply.
