This model operates in the H51 frequency band (534–598 MHz) and features transparent 24-bit digital audio processing and highly efficient spectrum utilization. The QLX-D system allows more compatible channels to be fit into one 8 MHz TV channel than any other system in its class.

The receiver has an integrated Ethernet port, which enables networked channel scanning for multiple receivers simultaneously and system control via Wireless Workbench software or the ShurePlus Channels mobile app (iOS/Android). To ensure secure data transmission, the QLXD4E uses AES-256 encryption, making it an ideal choice for government agencies or confidential meetings. Its robust metal construction ensures durability.
