Shure SLXD14/SM35-K59 Wireless Headset Microphone System

The Shure SLXD14UK/SM35-K59 is a wireless microphone system engineered to provide a seamless and reliable wireless experience, meeting the demands of professional touring environments. It offers high-resolution digital audio complemented by exceptional signal stability, ensuring optimal clarity and balanced sound reproduction.

The system features straightforward setup; frequency management is automated at the touch of a button, streamlining the process for efficient deployment. Designed for scalability, the SLX-D allows users to expand their system with assurance, accommodating configurations from a single channel to multiple channels while maintaining consistent wireless performance in any setting.

Authentic Shure sound - set free

The SM35 headset microphone has been integrated with forward thinking wireless technology. For pristine Shure quality audio, securely transmitted over a 100-meter range.

One-press IR sync establishes a rock-solid connection from your bodypack transmitter to receiver in a matter of seconds. Whilst a mini-LCD screen and intuitive controls let you see what's important. Navigate between group/channel, frequency, or battery runtime with ease. You can also engage 'lock mode' to prevent unwanted button presses mid-performance.

Powerful rechargeability options

SLX-D transmitters give you 8 hours of use from one pair of AA batteries. But why not take advantage of Shure's revolutionary rechargeable technology?

The optional SB903 lithium-ion battery provides a hefty 10 hours of run time. And you can see exactly how much life is left directly from your transmitter.

There are a variety of charging options too: the SBC10-903 Single-Battery USB charger. Or the SBC203 Dual Docking Station - which allows battery charging in or out of their transmitters thanks to external charging contacts. It only takes 2.5 hours to reach full power. Or in emergencies, a 15-minute quick-charge provides a vital hour of use.

Built for hard touring

A faulty wireless system can have show stopping consequences. Which is why SLX-D receivers are virtually bullet-proof. Made from enforced galvanized steel and put through extreme testing procedures, SLX-D is ready for the long haul. And then some.

And with the included rackmount kit you can install your entire wireless rig into a hardcase. For convenient and safe transportation from venue to venue.
