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 already set, press the channel button to scan for the best available channel.
3. Turn on the first transmitter. The blue rf LED will il-
luminate 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 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.

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.
1. Press the group button to select a group. The receiver automatically 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.
Number of Backup Notes
Frequencies
3 Initial factory setting.
3 Best multi-channel group if you experience interference.
0 For large multi-channel systems. Only use Group 3 in controlled Wi-Fi envi-
ronments because there are no backup frequencies to avoid interference.
27 Best single-channel group if you experience interference.

Note: Dashes appearing on the group and channel display
during a channel scan indicate that frequencies are not avail-
able in the selected group. Choose a group that supports
more receivers and repeat the set up steps.
