Shure GLXD14+E-SM31-Z4

GLX-D+: the new generation succeeding GLX-D and GLX-D Advanced

With the GLX-D+ series, Shure evolves its wireless solution by officially replacing the GLX-D and GLX-D Advanced ranges. The goal is clear: to offer a more reliable system for daily deployment, thanks to a wider spectrum range and increased battery life. In this context, the GLXD14+E-SM31-Z4 stands as a modern response to the current challenges of wave-congested environments, while maintaining the "plug and play" approach that made the GLX-D family successful.

A wireless system designed for fitness, hosting, and dynamic speaking

The GLXD14+E-SM31-Z4 is primarily aimed at active users: fitness coaches, fitness instructors, hosts, speakers, event presenters, or any situation where a handheld microphone becomes restrictive. The headset format allows hands-free use, speaking while maintaining a natural posture, and keeping a consistent voice level even during physical effort.

Thanks to its straightforward operation, this system is also well suited for organizations needing quick setup (sports studios, multipurpose rooms, mobile services), while seeking reliable audio quality and a stable RF connection.

RF reliability and battery life: key improvements of the GLX-D+

Dual-band 2.4 GHz / 5.8 GHz: more margin, less stress

The dual-band wireless technology of the GLX-D+ allows operation on both 2.4 GHz and 5.8 GHz. This approach significantly increases the available bandwidth and helps avoid interference to maintain stable, lossless sound. Practically, this is a major advantage in dense radio environments (presence of many devices, networks, and users).

Automatic frequency management and improved RF performance

Shure designed the GLX-D+ so that every critical step is managed automatically: frequency management and RF optimization are handled reliably, so the user doesn't have to constantly "pilot" the system. The system also supports up to 11 simultaneous systems under normal conditions, and 16 under optimal conditions, facilitating integration in multi-mic setups (group classes, events, studios).

Lithium-ion battery and smart charging: up to 12 hours

The included lithium-ion battery features a smart charging function and targets up to 12 hours of autonomy, covering a full day of classes or consecutive sessions. Charging can be done in multiple ways and includes fast charging capabilities, convenient for quickly putting the system back into service between sessions.
