2.4 GHz Spectrum Overview
GLX-D operates within the 2.4GHz ISM band which is utilized by Wi-Fi, Bluetooth, and other wireless devices. The benefit of
2.4GHz is that it’s a global band that can be used anywhere in the world, license free.
Overcoming the Challenges of 2.4GHz
The challenge of 2.4GHz is that Wi-Fi traffic can be unpredictable. GLX-D meets these challenges in the following ways:
•
Prioritizes and transmits on the best 3 frequencies per channel (choosing from a pool of 6 frequencies across the 2.4GHz
band)
•
Repeats the most important information such that one frequency can be taken out entirely without audio interruption
•
Continuously scans during usage to rank all frequencies (both current and backup frequencies)
•
Seamlessly moves away from interference to backup frequencies without audio interruption
Coexisting with Wi-Fi
If you plan to use WiFi during a performance, turn on WiFi devices prior to turning on GLXD and scanning for the best chan
nel. GLXD detects and avoids other WiFi traffic by scanning the entire 2.4GHz environment and selecting the 3 best frequen
cies to transmit on. The result of this is reliable performance for your GLXD wireless system as well as avoiding WiFi trans
missions which may be important as well.
“Bursting” WiFi is harder to detect as it is periodic; however, because GLXD repeats the most important information, even
bursts at very highlevels don’t have an effect on your audio performance.
Challenging Wireless Environments
Some environments are more difficult than others for 2.4 GHz wireless system performance. Additionally, body absorption has
a greater impact in the 2.4 GHz spectrum, compared to the UHF spectrum. The simplest solution in many cases is to reduce
the transmitter to receiver distance such as placing the receivers on the stage with a clear line of sight.
Challenging environments include:
•
Areas with few reflective surfaces such as:
◦
Outdoors
◦
Buildings with very high ceilings
•
3 or more GLX-D receivers in use
•
Strong Wi-Fi presence
•
Competitive 2.4 GHz systems in use
Note: Unlike analog TV band wireless which typically uses the same type of transmissions across manufacturers, all 2.4GHz wireless currently on the market
use different variations of wireless transmission. These differences make it more difficult to mix and match 2.4 GHz from multiple manufacturers successfully,
as can be done with TV band wireless solutions.

Shure Incorporated
Tips and Methods to Improve Wireless System Perfor-
mance
If you encounter interference or dropouts, try the following suggestions:
•
Scan for the best available channel (press the channel button)
•
Reduce transmitter to receiver distance - for example, place receivers on stage with a line of sight to the receiver.
•
Change the group for all GLX-D systems:
◦
Single-Chanel System: use Group 4, which is optimized for single-channel use
◦
Multi-Channel System: use Group 2, which is the most robust wireless group
•
Keep transmitters more than 2 meters (6 feet) apart
Note: GLX-D transmitters closer than 6 inches (15 cm) to other non-GLX-D transmitters may cause audible noise in that transmitter
•
Move receiver further away from Wi-Fi access points, computers, or other active 2.4 GHz sources.
•
Disable non-critical Wi-Fi on computers, cell phones, and other portable devices
◦
If you plan to use WiFi during a performance, turn on WiFi prior to turning on GLXD and scanning for the best chan
nel.
•
Avoid heavy Wi-Fi traffic activities such as downloading large files or viewing a movie.
•
Avoid placing transmitter and receiver where metal or other dense materials may be present
•
During sound check, mark trouble spots and ask presenters or performers to avoid those areas
•
If there is a known strong source of Wi-Fi and you specifically want to use frequencies within that Wi-Fi channel, use the
following Group/Channel of GLX-D (best option listed first):
◦
Wi-Fi 1: Group 3/Channel 8, Group 3/Channel 4
◦
Wi-Fi 6: Group 3/Channel 7, Group 3/Channel 5
◦
Wi-Fi 11: Group 3/Channel 2, Group 3/Channel 1

To power your GLXD6 wireless receiver pedal, we recommend using the included power supply or a power supply with isolated
power outputs.
If using a power supply with isolated power outputs, use a power outlet rated at a minimum of 250 mA.
However, if using other third-party power supplies:
•
Check the power consumption for each pedal in a daisy-chain setup. You must know the total power consumption for all of
your pedals to avoid overloading the power supply.
•
If no power requirement is listed on the pedal, consult the pedal manufacturer.
