Multiple Receiver Systems

To run more than two receivers at the same time, the GLX-D Frequency
Manager is recommended to improve RF reliability.
However, you can run multiple receivers without the frequency manager.
Select the group by determining the total number of receivers in your sys-
tem (channel count). All receivers in the system must be set to the same
group.
Channel Number
Count of Backup
Group
(Number of Frequencies Per
Receivers) Channel
1 Up to 4 3
2 Up to 5* 3
3 Up to 8* 0
4 1 27
*Environmentally dependent, 4 systems typical
See "Tips to Improve Wireless System Performance" section for additional
information. For information about receiver groups when connected to the
GLX-D Frequency Manager, see the UA846 user guide.
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 nec-
essary) or if the group is already set, press the chan-
nel button to scan for the best available channel.
3. Turn on the first transmitter. The rf LED turns sol-
id blue when a link is established.
Repeat steps 1-3 for each additional receiver and transmitter. Remember
to set each receiver to the same group.
See GLX-D Frequency Manager guide for setting up receivers and trans-
mitters when connected to the frequency manager.
Note: Dashes appearing on the group and channel display during a chan-
nel scan indicate that frequencies are not available in the selected group.
Choose a group that supports more receivers and repeat set-up steps.
Manually Linking a Transmitter to a
Receiver
Use the manual linking option to change the transmitter linked to a receiv-
er. 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.

Tip: Monitor the audio and observe the receiver audio meter level while
adjusting the gain to prevent signal overload.
Locking and Unlocking the Controls
The controls of the receiver and transmitter can be locked to prevent acci-
dental or unauthorized changes to settings.
Note: Locks are not affected by power cycles.
