The Shure QLXD4E-K51 Wireless Receiver is a reliable and high-performance stationary receiver for wireless systems. Harnessing technology from Shure’s most advanced systems, it provides unparalleled signal stability. This receiver is built to perform in challenging environments, making it elevated wireless.
One of its powerful features is the Automatic Channel Scan, which quickly locates clear frequencies at the press of a button. Dropouts are eradicated thanks to intelligent Predictive Switching, making it effortless to run multiple systems.
For large events, the Shure QLXD4E-K51 is the ultimate choice. With the Network Scan feature, it is remarkably simple to set up many systems at once. A single receiver will scan and deploy open frequencies to all connected receivers via Ethernet. This allows for the coordination of up to 60 channels in just a few seconds, which is invaluable during high-profile productions where the RF environment can change dramatically.
The Shureplus Channels App allows for remote monitoring and control of the wireless rig. From an iPad or iPhone, users can view battery levels, RF status, audio levels, and more. Real-time gain adjustments can also be made, making it a convenient and intuitive tool for controlling the entire networked system.
To keep presentations confidential, the Shure QLXD4E-K51 offers AES-256 Encryption. This encryption establishes a private one-to-one relationship between the transmitter and receiver, ensuring an impenetrable wireless transmission.
