Multiple Receiver Systems
If several channels of wireless audio are needed, up to 8 GLX-D receivers can operate simultaneously in the 2.4 GHz spectrum. 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
interference from unexpected Wi-Fi devices.
Group Channel Backup
Count Frequencies
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
display 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 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.
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.
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 supports more
receivers 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 channel
scan indicates that there are no available channels within the selected group.
Choose a group with more channels and repeat set up steps.
