Shure QLXD4E G51

Shure QLXD4E G51 – single-channel digital wireless receiver in a half-rack chassis, European version operating in the G51 band (470-534 MHz), sold without a transmitter. The receiver processes 24-bit audio at 48 kHz with AES-256 encryption enabled from the factory and digital predictive switching diversity, which switches antennas before a signal gap occurs. The half-rack (PAR 9.5) housing fits a standard 19-inch rack when two units sit side by side, making it easy to expand a rig with more channels without using extra mounting space. The G51 band offers up to 72 MHz of switching bandwidth and 22 compatible channels within a single 8 MHz TV channel.

Flexible integration with existing transmission gear

The receiver works with the QLXD2 handheld transmitter, the QLXD1 bodypack, or the QLXD3 plug-on transmitter, letting you match the transmission type to the task at hand - vocals, an acoustic instrument, or a camera-mounted plug-on mic - without swapping the receiver itself when the application changes. That flexibility makes it easier to build a mixed rental inventory, where the same receivers serve different configurations depending on the client's order.

Operating in the European G51 band without regulatory overreach

The E version, cleared for the G51 band under regulations in force across Europe, lets you run an installation without manually restricting the frequency range to permitted spectrum slices. Automatic frequency scanning and IR sync deploy a clean channel to the transmitter within seconds, and the Ethernet port coordinates multiple receivers in a single installation through Wireless Workbench software, cutting the risk of accidentally straying outside the allowed band.
