Multiple Receiver Systems

For ease of set up, available frequencies are divided into three groups based on the number of receivers supported.
All receivers in the system must be set to the same group. To select a group, determine the total number of receivers in the system (channel count), and
then select the appropriate group.
Note: To maximize the number of receivers on-air, Group 3 does not offer backup frequencies. Group 3 should only be used in controlled Wi-Fi environments to prevent inter-
ference from unexpected Wi-Fi devices.
Group Channel Backup Frequencies
Count Available?
1 Up to 4 Yes
2 Up to 5 Yes
3 Up to 8 No
Note: If you experience interference, reduce transmitter to receiver distance and set all GLX-D systems to group 2, which is the most robust wireless group.
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 already 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.
Selecting a Group
1. Press and hold the group button for 2 seconds until the group dis-
play flashes.
2. Press the group button to scroll through the available groups.
3. The receiver will automatically save the selected 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 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.
Notes
Initial Factory Setting.
Best Group to use if you experience interference.
Only use Group 3 in controlled Wi-Fi environments because there are no backup frequencies to avoid
interference.

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 adjusted and stored
independently 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 automatically
2. Turn on transmitter 1 and link it to the receiver. Adjust the gain, and
3. Turn on transmitter 2 and link it to the receiver. Adjust the gain, and
Note: Dashes appearing on the group and chan-
nel display during a channel scan indicate that
frequencies are not available in the selected
group. Choose a group that supports more re-
ceivers and repeat the set up steps.
Selecting a Channel
1. Press and hold the channel button for 2 seconds until the channel
display flashes.
2. Press the channel button to scroll through the available channels.
3. The receiver will automatically save the selected channel.
Note: A double dash symbol -- displayed on the receiver screen during a chan-
nel scan indicates that there are no available channels within the selected group.
Choose a group with more channels and repeat set up steps.
