Multiple Receiver Systems
For ease of set up, frequencies are divided into groups to best match the channel requirements for your system.
Select the group by determining the total number of receivers in your system (channel count). All receivers in the system must be set to the same group.
Group Channel Count
(Number of
Receivers)
1 Up to 4
2 Up to 5*
3 Up to 8*
4 1
*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.
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.
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 Channel
1. Press and hold the channel button for 2 sec-
onds 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 --
nel scan indicates that there are no available channels within the selected group.
Choose a group with more channels and repeat set up steps.
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.
