SHURE QLXD4E=-K51 Receiver

Shure QLXD4E Digital Wireless Receiver (K51 Frequency Band)

The Shure QLXD4E is a high-class, half-rack digital wireless receiver designed for professional events, conference centers, and live sound installations. This model operates in the K51 frequency band (606–670 MHz) and features clear 24-bit digital audio processing and highly efficient radio spectrum utilization. The QLX-D system allows for more compatible channels in a single 8 MHz TV channel than any other system in its class, ensuring stable performance even in heavily loaded environments.

The receiver has an integrated Ethernet network port, enabling network channel scanning for multiple receivers simultaneously and system control via "Wireless Workbench" software or the "ShurePlus Channels" mobile application. To ensure secure data transmission, the QLXD4E uses AES-256 encryption, making it an ideal choice for government agencies or confidential business meetings. The robust metal construction ensures durability and reliability.
