Ready-To-Go. Every time. Automatically.
The new GLX-D+ Dual Band Wireless System features the versatile SM31 Headset Microphone for spoken word applications and the GLXD4R+ tabletop receiver. The perfect combination of the automatic frequency management with the new Dual Band Technology provides reliable and consistent performance, while Shure proprietary Lithium-Ion rechargeable batteries provide up to 12 hours of use. Go wireless without complication.

This Shure wireless system can handle your most intense workouts. The SM31 Fitness Headset is made from corrosion proof materials. You can sweat on it. Shout into it. And it will perform just as you need it. And it’s been fused with elegant GLX-D technology – for wireless freedom you can really trust.
Setup is simple. Intelligent LINKFREQ technology finds the best frequency for your performance. And if competing signals are detected from nearby Wi-Fi and Bluetooth devices, your receiver will automatically switch to a new, clear frequency. It’s totally seamless, with zero interruption to the audio. Just fault free performance, every time you workout.

No more interference
You don’t need to worry about nearby Wi-fi and Bluetooth devices disrupting your signal. LINKFREQ frequency management intelligently responds to your environment, to give you crystal clear, unbroken sound.

It works by continuously scanning the available frequency spectrum, and automatically selects the best open channel. When troublesome Wi-Fi and Bluetooth signals start to interfere, the receiver will seamlessly change to a new clear frequency. This is complimented by true diversity operation, which compares and selects the strongest signal from the receiver’s two antennae. It’s all so smart and seamless, you can’t even hear it happen. All you hear is pristine, full bandwidth digital audio.

With technology this agile and adaptive, you’re able to run up to eight GLX-D systems at once. So you can expand your wireless set up whenever you need to.

Rechargeable lithium ion battery…
AA batteries can be costly and inconvenient. You’re never sure how long they have left, so you swap them prematurely. Or worse, they die mid performance. That’s why GLX-D transmitters use a rechargeable lithium ion battery. And the high-resolution screen shows you exactly how much charge you have left, in hours and minutes. For total peace of mind when your performing.
To recharge, simply insert the battery into the port on the front of the receiver. Or leave it inside the transmitter and connect the USB cable. You can even charge a spare battery whilst performing. You’ll get a generous 16 hours of continuous use from a full battery. Or in emergencies, a 15 minute quick-charge will give you an indispensable hour and a half of run time.

SM31 Headset and Bodypack Transmitter…
The SM31 Fitness Headset has been specially made for aerobics and fitness instructors. Its rugged, wire-form design is built to last, and will stay in place even during high energy workouts. And because it’s been assembled with lightweight components, you can comfortably wear it for hours. It sounds exceptionally clear too, offering the same quality as Shure’s famous handheld mics. And thanks to moisture resistant fabrics, the mic capsule is completely safe from sweat. The headset plugs straight into the GLXD bodypack transmitter, which will automatically link with your GLXD receiver, for seamless frequency matching. And you can faithfully performs up to 30 meters (100 feet) away. So you’re free to move around the room, as much as you need.
