Set Up the Frequency Manager
Connect each antenna to the antenna A and antenna B outputs on the rear panel.
If mounting in equipment rack, use included rackmount hardware to mount as shown.
Connect power supply to power outlet and to the power in on the rear panel.
Power each receiver by connecting a DC power cable between the frequency manager's power out and the receiver's
power input.
Use reverse SMA cables to connect the frequency manager's RF A and RF B ports to each receiver's antenna A and
antenna B inputs.
Note: If mounting antennas remotely, see Remote Antenna Placement.

Selecting Frequency Groups
The frequency manager creates a shared group of frequencies for all receivers to use, and automatically assigns frequencies
to each receiver. If interference occurs, the frequency manager assigns new frequencies without audible dropouts.
Usingasharedgroupoffrequenciesforallreceiverspreventsonereceiverfromusingallofthebestfrequencies,anditim
proves RF reliability.
Press the power button to turn on the frequency manager.
Press the power button on the first receiver. The white data sync LED flashes while searching for frequencies.
Select a group for all receivers by pressing and holding the group button for two seconds.

Linking Transmitters and Receivers
Important: Before beginning, turn off all receivers and transmitters. Turn on and link each receiver/transmitter pair one at a
time to prevent cross-linking
Afterselectingagroupusingthefirstreceiver,turnonthefirsttransmitter.TheblueRFLEDwillflashwhilethetrans
mitter and receiver form a link. When the link has successfully formed, the RF LED will remain illuminated.
Turn on the second transmitter and repeat for each additional receiver/transmitter pair to finish linking.
Connecting Multiple Frequency Managers
Connect2frequencymanagersifusingmorethan6receivers,orconnect3frequencymanagersifusingmorethan11re
ceivers. Use the cascade A and cascade B ports to connect the frequency managers. Frequency managers can be cascaded
up to a maximum of 16 receivers.
Use reverse SMA cables to connect the cascade A and cascade B ports on the first frequency manager to the antenna
A and antenna Bportsonthesecondfrequencymanager.Repeatthissequencetoconnectthesecondfrequencyman
ager to a third frequency manager.

Connect receivers according to the diagram. For example, use the A2 and B2 ports to connect a second receiver, then
use the A3 and B3 ports to connect a third receiver. When using 2 frequency managers, the cascade A and cascade B
ports on the second frequency manager connect to a sixth receiver.
Note: Do not use a passive antenna splitter with the frequency manager. Frequency manager features will not work.
Remote Antenna Placement
Follow these guidelines when mounting antennas remotely:
Reduce distance between transmitter and antenna.
Mount antennas farther from each other to improve performance.
Position antennas so there is nothing obstructing the line of sight to the transmitter, including the audience.
Keep antennas away from metal objects and any other antennas.
Use only low-loss reverse SMA cable to avoid poor RF signal.
Consult cable's specifications and calculate signal loss for desired cable run.
Use one continuous length of cable from the antenna to the receiver to increase signal reliability.
Alwaysperformawalkaroundtesttoverifycoveragebeforeusingawirelesssystemduringaspeechorperformance.Ex
periment with antenna placement to find the optimum location. If necessary, mark any trouble spots and ask presenters or
performers to avoid those areas.
Receiver Channel Display
When connected to a frequency manager, each receiver's channel field displays a unique identifier that won't change unless
you plug in to a different set of ports on the frequency manager. Use this channel display to help label transmitters or to identify
where each receiver is plugged in on the frequency manager.

GLXD4+ and GLXD6+ Receivers
GLXD4+ and GLXD6+ receivers cannot connect to the GLX-D+ frequency manager.
If you plan to use a GLXD4+ or GLXD6+ receiver in addition to a frequency manager, set up the GLXD4+/GLXD6+ receiver
first. Then turn on and set up the frequency manager.
Note: Using GLXD4+/GLXD6+ receivers alongside a frequency manager will affect the maximum number of channels you can operate with each group.
