*Environmentally dependent, 4 systems typical
See "Tips to Improve Wireless System Performance" section for additional information.
Setting Up Receivers and Transmitters
Note: Before beginning, turn off all receivers and transmitters. Turn on and set up each receiver/transmitter
pair individually to prevent cross-linking.
1. Turn on the first receiver.
2. Press and hold the group button to select a group (if necessary) or if the group is al-
ready set, press the channel button to scan for the best available channel.
3. Turn on the first transmitter. The blue rf LED will illuminate 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 Selecting a Group and Channel
Specific groups and channels can be assigned to the receiver instead of using the automatic scan function.
Note: Group 3 should only be used in controlled Wi-Fi environments to prevent interference from unexpected Wi-Fi devices.
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 trans-
mitter 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.
Note: Dashes appearing on the group and channel display
during a channel scan indicate that frequencies are not
available in the selected group. Choose a group that sup-
ports more receivers and repeat the set up steps.
Selecting a Group
1. Press and hold the group button for 2 sec-
onds until the group display flashes.
2. Press the group button to scroll through the available groups.
3. The receiver will automatically save the selected group.
Selecting a Channel
1. Press and hold the channel button for 2 sec-
onds until the channel display flashes.

Linking Multiple Transmitters to a Receiver
Link multiple transmitters to the same receiver to allow for instrument
changes during a performance. Only one transmitter can be active at a
time, otherwise the signals will interfere with each other.
After linking the transmitters, gain settings can be set and stored indepen-
dently for each transmitter.
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 automati-
cally 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
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 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.
“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.
Challenging Wireless
Environments
Some environments are more difficult than
others for 2.4 GHz wireless system perfor-
mance. 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 trans-
mitter 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.
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)
• 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 wire-
less 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 Wi-Fi during a performance, turn on Wi-Fi prior
to turning on GLX-D and scanning for the best channel.
• 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

clignote lorsque l'émetteur et le récepteur
établissent une liaison. Lorsque la liaison
a été établie avec succès, la LED rf reste
allumée.
Remarque : l'émetteur et le récepteur demeur-
ent liés pour une utilisation future. À la mise en
marche, la LED rf bleue s'allume directement,
sans passer par l'étape de liaison.
