Shure QLXD4 Digital Wireless Receiver (G50: 470 to 534 MHz)

The Shure QLXD4=-G50 is a digital wireless receiver that sits comfortably in a half-rack space and covers the G50 frequency range of 470 to 534 MHz. Designed for engineers who need dependable RF performance without lengthy setup, it offers a straightforward path from power-on to show-time.

Automatic channel scanning locates open frequencies across the 64 MHz tuning window, and one-touch IR sync transfers those settings to a compatible QLX-D transmitter in seconds. When you are running several receivers on the same network, Ethernet connectivity lets the units share scan results, so large multi-channel rigs stay organized with minimal manual work.

Audio quality stays consistent thanks to digital predictive switching diversity, a technology that maintains a solid RF link even in crowded environments. An adjustable audio gain range of up to 60 dB lets you match levels to a variety of sources, whether it is a quiet lavalier on a presenter or a hot handheld mic for a lead vocalist.

Security is often a concern in corporate boardrooms and houses of worship. AES 256-bit encryption keeps the signal private, while the high-contrast LCD with a lockout option prevents accidental changes during a live event. You can monitor and control every setting from a computer through Shure Wireless Workbench or from an iOS device with the ShurePlus Channels Mobile App, making on-the-fly adjustments easy even when the rack is out of reach.

The aluminum chassis handles life on the road, and the detachable half-wave antennas simplify storage or antenna distribution. Balanced XLR and quarter-inch outputs accommodate both mic-level mixers and line-level instrument rigs, so the receiver drops into touring racks, permanent installs, and portable PA systems with equal ease.

Whether you are coordinating wireless for a concert, streaming a lecture on campus, or managing audio in a conference hall, the QLXD4=-G50 provides the stability, control, and sound quality that professionals expect from Shure.
