Product Overview
Shure's dropout-free GLXD14+/SM31 Dual Band Digital Wireless system lets you Lead your fitness classes with total confidence, providing rock-solid performance so you can focus on the training. The GLXD14+/SM31 includes a tabletop receiver, bodypack transmitter, and SM31FH cardioid fitness headset microphone with moisture-repellent hydrophobic fabric that protects the element from corrosion. An included windscreen tames plosive and breath noise for clear, intelligible vocal reproduction. The low-profile, lightweight adjustable headset provides a secure fit that eliminates user fatigue, ensuring comfort even during extended high-impact use. With its advanced Dual Band Wireless Technology, GLXD+ operates in the license-free 2.4 and 5.8GHz ranges, providing more than double the available bandwidth and intelligently avoiding interference. The GLXD14+/SM31 is a tabletop system that's easy to set up and operate thanks to auto-pairing and Smart frequency management. The transmitter features a twelve-hour runtime battery making power concerns a thing of the past. Of course, things don't always go as planned. So Shure engineered the SB904 battery to deliver a 1.5-hour runtime from a 15-minute quick charge. And you have options because the SB904 can be recharged in the receiver's front panel or via USB-C while still in the transmitter. Get your GLXD14+/SM31 today and experience the freedom!
