What is the main difference between GLX-D Advanced Digital Wireless and the current GLX-D Wireless Systems?
GLX-D Digital Wireless Systems are not rack mountable. They store within their own carrying cases and feature high-quality sound, automatic frequency management and rechargeability.
The GLX-D Advanced Digital Wireless includes Frequency Managers, rack mount receiver systems, remote antennas and accessories. All these combine flexibly for applications such as houses of worship, schools, auditoriums and venues with multiple wireless system requirements.
What is “LINKFREQ Technology”?
LINKFREQ Automatic Frequency Management is the latest proprietary Shure wireless technology platform, developed specifically to optimize wireless transmitter and receiver performance in the 2.4GHz frequency band. Powering up a GLX-D receiver and transmitter establishes an automated link between them, and GLX-D receiver begins to continuously analyze the active RF spectrum and determine which frequencies are best for transmission. Once identified, the frequencies are deployed via the established link to both the transmitter and receiver, automatically setting both wireless components simultaneously.
Additionally, in the presence of RF interference, the GLX-D receiver and transmitter will seamlessly move together to clean frequencies with no audio signal interruption.
How do you optimize wireless performance?
To optimize wireless performance it is recommended to:
- Use GLX-D Advanced Frequency Managers linked to GLXD4R rack mount receiver systems for improved RF performance.
- PA805Z2-RSMA Passive Directional Antennas can both improve desired signal and minimize interfering signals. If an access point is next to the receivers, locate the Passive Directional Antennas further away from the receivers - even have the rear facing the access point.
- Locate receivers ~10FT away from 2.4GHz sources such as wireless access points, computers, and other Wi-Fi devices.
- Minimize distance from transmitters to receivers- this is true of all wireless systems and 2.4GHz is no different.
I already own GLX-D Digital Wireless systems. Can I use my GLXD4 or GLXD6 receivers with the GLX-D Frequency Manager to get additional systems on air?
Unfortunately, no. The GLX-D Frequency Manager is designed specifically to work with receivers that can be rack-mounted and have detachable antennas. GLXD4 and GLXD6 receivers do not have either of those features, so at best the GLX-D Frequency Manager could be used in conjunction with GLX-D rack mount systems alongside the systems you currently own.
