Shure GLXD14r+E-SM31-Z4

Essential Information About the Shure GLXD14R+E-SM31-Z4 Rackable Wireless System

• Enhanced reliability thanks to dual-band wireless technology (2.4 GHz and 5.8 GHz) to minimize interference and secure transmission.


• Complete stage-ready pack: rackable GLXD+ receiver + bodypack transmitter + fitness headset microphone SM31FH.


• Optimized battery life with rechargeable lithium-ion battery offering up to 12 hours of use, featuring intelligent charging and fast charge.


• Simplified setup: automatic RF management and capability to use up to 11 systems simultaneously (and 16 under optimal conditions).

A New Generation GLX-D+: The Official Successor to GLX-D

With the GLX-D+ series, Shure evolves its consumer/professional digital solution by officially replacing the GLX-D and GLX-D Advanced. The goal is clear: maintain the "plug-and-play" philosophy that made the range successful, while delivering tangible improvements in radio environment and battery life. The GLXD14R+E-SM31-Z4 fits this logic with a rackable format designed for clean installations, touring setups, and control rooms, while remaining easy to deploy.

Who Is It For and What Are Its Uses? Reliable Wireless for Voice in Motion

This system is particularly suited for those who need a stable and comfortable microphone in dynamic situations: fitness coaches, dance instructors, hosts, speakers, presenters, as well as musicians or technicians seeking a discreet solution for spoken or sung voice with a headset. The SM31FH microphone, designed to stay in place during exertion, ensures clear and consistent speech even when the user moves a lot.

The rackable receiver format is a real advantage when working with multiple sources, a rack, a flight case, or a fixed installation: cleaner cabling, quick access, and natural integration into a sound reinforcement or conference system.

GLX-D+ Technology: RF Stability, Battery Life, and Everyday Simplicity

Dual-Band Digital Transmission: 2.4 GHz and 5.8 GHz

The major advancement of GLX-D+ lies in its dual-band operation: the system can operate on both 2.4 GHz and 5.8 GHz. This approach greatly increases available bandwidth and helps avoid congested areas, for a smoother wireless experience and reliable sound "without surprises." The idea is to let you focus on the content (performance, class, speech) rather than the technology.

Up to 12 Hours Battery Life: A Battery Designed for the Field

The GLX-D+ incorporates intelligent charging and a lithium-ion battery rated for up to 12 hours of autonomy. In practice, this provides real comfort for back-to-back rehearsals, events, and performances, while reducing battery management. Fast charging and various charging options (depending on configuration) also secure busy days where every minute counts.

Automatic Frequency Management and Multi-System Performance

For environments where multiple wireless links coexist, the GLX-D+ series aims for simple use with automatic RF frequency management. Shure announces a capacity of up to 11 simultaneous systems under normal conditions, and 16 under optimal conditions. This is a valuable asset for gyms, hotels, conference centers, schools, places of worship, or studios where radio density can quickly increase.

Rackable Format, Detachable Antennas, and GLX-D+ Ecosystem

The rackable GLXD+ receiver is designed to integrate neatly into racks and facilitate stage organization. The detachable antennas allow you to adapt the setup according to your constraints (placement, accessibility, reception optimization). The system is also announced compatible with the GLX-D+FM dual-band frequency manager, useful for structuring a GLX-D+ wireless fleet as your needs evolve.
