Shure QLXD Custom Wireless Headset 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.

Rechargeable battery options

Your QLX-D transmitter provides a generous 9 hours of continuous use from the pair of included AA batteries.

Or take advantage of Shure's revolutionary rechargeable technology. The optional SB900 lithium ion battery provides 10 hours of run time. And you can see exactly what's left in hours and minutes on the transmitter. There are a variety of charging options too: an eight-bay charger, a single-battery USB charger, and the dual docking station. Which allows transmitter charging without removing the battery, thanks to the external charging contacts. It only takes 3 hours to reach full capacity. Or in emergencies, a 15 minute quick-charge provides a vital hour of use.

Pro-grade construction

Built to survive the demanding nature of professional touring. QLX-D transmitters and receivers are constructed with a robust, yet lightweight aluminium. Chosen to keep the high-caliber components safe from detrimental wear and tear. And with the included rackmount kit, you can integrate your new system straight into your current rig. For safe transportation from venue to venue.
