Multiple System Set Up
Up to 12 systems can operate simultaneously (band and RF environment dependent).
Important: Set up each system one-at-a-time. Once a receiver and transmitter are tuned to the same group and channel, leave the transmitter powered
on. Otherwise, scans from the other receivers will not detect that channel as occupied.
Turn on any other equipment that could cause interference during the performance so it will be detected during the group and channel scans in the fol-
lowing steps.
Before you begin system set up, turn all receivers
ON and all transmitters OFF .
For the first receiver:
1. Perform a group scan to find the group with the most clear channels.
2. Turn on the first transmitter and change the group and channel to match the receiver.
3. Leave the transmitter on and continue with the additional systems.
Note: If the selected group does not contain enough open channels, manually select group "d" when setting up larger systems.
For each additional receiver:
1. Manually change the receiver to match the group setting of the first receiver. Recall that each time the group setting is changed, a channel scan is
automatically done.
2. Turn on the transmitter and change the group and channel to match the receiver.
3. Leave the transmitter on and continue to the next system.
4. Once all receivers are set up, perform an audio check on all microphones.
Manually Setting Receiver Group and Channel
The receiver group may need to be changed as part of a multiple system setup.
Group (letter)
1. Hold the group button on the receiver until the display begins to flash.
2. While the display is flashing, press the group button again to advance to the next group.
Note: Only the group setting will be displayed during the manual setup.
3. Once the desired group is reached, release the group button. The receiver automatically performs a channel scan.
Channel (number)
Always use a channel selected by the channel scan. However, if necessary, the channel can be set manually. Follow the same steps above using the
channel button instead of the group button.
