Quick Start  
To reduce set up time, the transmitter and receiver automatically link to form an audio channel the first time they are powered on and never have to be linked again.  
Note: When setting up multiple receiver systems, turn on and link each transmitter/receiver pair one at a time to prevent cross-linking.  
Step ②  
Install charged transmitter  
batteries.  
Step ①  
Connect power supply to the receiver and plug cord into an AC power source.  
Connect the audio output to an amplifier or mixer.  
Step ③  
Step ④

Batteries and Charging  
GLX-D transmitters are powered by Shure SB902 lithium-ion rechargeable batteries. Advanced battery chemistry maximizes runtimes with zero memory effects, eliminating  
the need to discharge batteries prior to charging.  
When not in use, recommended battery storage temperature is 10°C (50°F) to 25°C (77°F).  
Note: The transmitter will not pass RF or audio signals when connected to the charging cable.  
The following battery charging options are available:  
Charging from an AC Power  
Charging from a USB Port  
Receiver Charging Bay  
1. Plug the USB charging cable into the  
charging port on the transmitter.  
Source  
The GLXD4 receiver has a built-in charging bay for the  
transmitter batteries.  
1. Plug the charging cable into the charg-  
ing port on the transmitter.  
2. Plug the cable into a standard USB port.  
1. Insert the battery into the charging bay.  
2. Plug the charging cable into an AC power source.  
2. Monitor the battery charging indicator on the  
front panel until charging is complete.

Multiple Receiver Systems  
For ease of set up, frequencies are divided into groups to best match the channel requirements for your system.  
Select the group by determining the total number of receivers in your system (channel count). All receivers in the system must be set to the same group.

luminate when a link is established.  
Repeat steps 1-3 for each additional receiver and transmitter. Remember to set each  
receiver to the same group.  
Manually Linking a Transmitter to a Receiver  
Use the manual linking option to change the transmitter linked to a receiver. A common use for manual linking is changing the linked transmitter from a bodypack type to a  
handheld type.  
1. Turn on the transmitter: Within 5 seconds, press and hold the LINK button until the transmitter LED begins to flash green.  
2. Press and hold the link button on the receiver: The blue rf LED will flash, and then remain on when the link has been established.  
3. Test the audio to verify the link and adjust the gain if necessary.  
Combo Systems  
A combo system is created by linking two transmitters to a single receiver. Only one transmitter can be active at a time to prevent cross interference. Gain settings for each  
transmitter can be independently set and stored when the transmitter is active.  
Important! Do not turn on and operate both linked transmitters at any time.  
Turn off both transmitters before beginning.  
1. Press the group button to select a group. The receiver automatically scans the selected group to find the best available channel.  
2. Turn on transmitter 1 and link it to the receiver. Adjust the gain, and then turn off the transmitter.  
3. Turn on transmitter 2 and link it to the receiver. Adjust the gain, and then turn off the transmitter.

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  
Coexisting with Wi-Fi  
Challenging Wireless  
Environments  
If you plan to use Wi-Fi during a perfor-  
mance, turn on Wi-Fi devices prior to turn-  
ing on GLX-D and scanning for the best  
channel. GLX-D detects and avoids other  
Wi-Fi traffic by scanning the entire 2.4GHz  
environment and selecting the 3 best fre-  
quencies to transmit on. The result of this is  
reliable performance for your GLX-D wire-  
less system as well as avoiding Wi-Fi trans-  
missions which may be important as well.  
The challenge of 2.4GHz is that Wi-Fi traffic can be  
unpredictable. GLX-D meets these challenges in the  
following ways:  
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.  
• Prioritizes and transmits on the best 3 frequencies  
per channel (choosing from a pool of 6 frequencies  
across the 2.4GHz band)  
Challenging environments include:  
• Repeats the most important information such that  
one frequency can be taken out entirely without  
audio interruption  
• Areas with few reflective surfaces such as:  
“Bursting” Wi-Fi is harder to detect as it is  
periodic; however, because GLX-D repeats  
the most important information, even bursts  
at very high-levels don’t have an effect on  
your audio performance.  
- Outdoors  
- Buildings with very high ceilings  
• Continuously scans during usage to rank all fre-  
quencies (both current and backup frequencies)  
• 3 or more GLX-D receivers in use  
• Strong Wi-Fi presence  
• Seamlessly moves away from interference to back-  
up frequencies without audio interruption  
• 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.  
Tips and Methods to Improve Wireless System Performance  
If you encounter interference or dropouts, try the following suggestions:  
• Scan for the best available channel (press the channel button).  
• Locate competitive 2.4 GHz receivers away from each other  
• Avoid placing transmitter and receiver where metal or other dense materials  
may be present  
• Reduce transmitter to receiver distance - for example, place receivers on stage  
with a line of sight to the front of the receiver.  
• Move the receiver to the top of the equipment rack  
• Keep transmitters more than 2 meters (6 feet) apart - this is less critical at  
shorter receiver to transmitter distances  
• 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  
Note: If transmitters are within 6 inches of non-GLXD transmitters or micro-  
phone cartridges, audible noise is possible.  
• Move receiver further away from Wi-Fi access points, computers, or other active  
2.4 GHz sources. Recommended distance is a minimum of 3 meters (10 feet).  
• During sound check, mark trouble spots and ask presenters or performers to  
avoid those areas  
• Disable non-critical Wi-Fi on computers, cell phones, and other portable devices  
• If there is a known strong source of Wi-Fi and you specifically want to use fre-  
quencies within that Wi-Fi channel, use the following Group/Channel of GLX-D  
(best option listed first):  
- If you plan to use Wi-Fi during a performance, turn on Wi-Fi prior to turning on  
GLX-D and scanning for the best channel.  
• Keep the transmitter and receiver more than 2 meters (6 feet) apart  
- 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  
• Avoid heavy Wi-Fi traffic activities such as downloading large files or viewing a  
movie.

plug) produces positive voltage on pin 2 (with respect to pin 3 of low-impedance output) and the  
tip of the high impedance 1/4-inch output.

Information to the user  
This equipment has been tested and found to comply with the limits for a Class B  
digital device, pursuant to Part 15 of the FCC Rules. These limits are designed to  
provide reasonable protection against harmful interference in a residential installa-  
tion. This equipment generates uses and can radiate radio frequency energy and,  
if not installed and used in accordance with the instructions, may cause harmful  
interference to radio communications. However, there is no guarantee that interfer-  
ence will not occur in a particular installation. If this equipment does cause harmful  
interference to radio or television reception, which can be determined by turning the  
equipment off and on, the user is encouraged to try to correct the interference by one  
or more of the following measures:  
22µF
