Shure QLXD Custom Wireless Handheld Microphone System; K51

Full Description

Run multiple systems in harmony

The ultimate choice for large events. Thanks to a powerful new feature called Network Scan, it's now remarkably simple to set up many systems at once. A single receiver will scan and deploy open frequencies to all connected receivers via Ethernet. In just a few seconds, you can coordinate the frequencies of up to 60 channels.

This is invaluable during high-profile productions, where the RF environment can change dramatically because of TV equipment or security personnel. Just initiate a network scan, and let your system adapt to the new RF environment for you.

Remote monitoring and control

During a performance, it's not always convenient to quickly access your wireless rig. But thanks to the Shureplus Channels App, now you have the power to control your entire networked system from anywhere. Unlock a host of intelligent features from your iPad or iPhone. View each channel’s battery level, RF status, audio level and more. You can even make real-time gain adjustments. It's intuitive and easy. There's no need to be braced by the receivers for a whole performance.

Top tier encryption

Keep your presentation confidential with AES-256 Encryption. When engaged, it establishes a private one-to-one relationship between transmitter and receiver. For an impenetrable wireless transmission. Approved by the best cryptographers in the world, AES-256 is the highest standard of encryption available. So you can share sensitive information, with total peace of mind.
