Operates in the G50 frequency band 470 to 534 MHz

With transparent 24-bit digital audio quality and incredibly efficient RF spectrum usage, the QLXD4 Digital Wireless Receiver combines professional features with streamlined setup and operation.

Automatic scanning quickly finds open frequencies, and one-touch IR sync quickly deploys them to transmitters.

Ethernet networking enables networked channel scanning across multiple receivers and Wireless Workbench® software integration for remote control of receiver settings from a PC or Mac. Remote monitoring and control from iOS devices also is available via the ShurePlus™ Channels Mobile App.
