Dual-Band Technology for Easy and Reliable Wireless Performance
GLX-D+ Dual-Band Digital Wireless systems operate in both the 2.4 and 5.8 GHz frequency ranges, automatically scanning both to select the one that offers the higher number of clean channels.
The previous GLX-D only worked in the 2.4 GHz range, which offers 83.5 MHz of bandwidth. By expanding into the 5.8 GHz range, the GLX-D+ provides an additional 125 MHz worth of potential open frequencies for available channels, helping to minimize dropouts and enhance reliability.
The system offers true digital diversity, which means two antennas and two independent receiver modules work together to reduce RF signal dropouts.
In addition, the GLX-D+ transmits on its own main frequency just like a traditional system, but it also transmits on 2 extra “backup frequencies” at the same time. If the system detects interference on the main frequency, it will switch to one of the backups automatically without the user even knowing.
Besides the additional spectrum, there are other benefits to in operating in the 5.8 GHz range. In general, there are fewer devices operating in this range, making the spectrum cleaner. The 2.4 GHz range is home for Bluetooth devices and other devices, including Wi-Fi routers and repeaters, security cameras, baby monitors, garage door openers, and more. Operating in this range means competing with these devices for the same space.
GLX-D+ receivers typically allow you to run up to 4 mics simultaneously in the same space. Under ideal conditions, up to 8 systems can be used.
If you need more mics at once, consider the GLXDR+ half-rack receiver, which offers removable antennas and can accommodate the GLXD+FMZ3/LC Frequency Manager (available separately). The frequency manager allows up to 11 mics to operate simultaneously (16 under highly optimal conditions) making it ideal for installations with multiple wireless systems.

Key Features
For Small Venues, Presentations & Events
Single-Channel, Portable Tabletop Design
Works with GLX-D+ Transmitters
Auto Scans 2.4 and 5.8 GHz Frequencies

The Shure GLXD4+ is a single-channel digital wireless receiver housed in a tabletop chassis with two fixed front-panel antennas and compatible with the GLXD1+ bodypack and GLXD2+ handheld transmitters (available separately). Compact and lightweight, it is ideal for portable use, and it is very easy to use. Shure’s next-generation technology automatically scans both the 2.4 and 5.8 GHz frequency ranges to seek out the best possible digital transmission channel to ensure dependable performance for your presentations, performances, conferences, and events at a typical range of up to 100′ indoors and 65′ outside.
