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.
Turn on the transmitter: Within 5 seconds, press and hold the LINK button until the transmitter LED begins to flash
green.
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.
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 pre
vent 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.
Press the group button to select a group. The receiver automatically scans the selected group to find the best available
channel.
Turn on transmitter 1 and link it to the receiver. Adjust the gain, and then turn off the transmitter.
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
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.
