General Description

The GLX-D Frequency Manager distributes RF signal and DC power for Shure GLXD4R receivers. The rack-mountable system increases channel count and reduces the number of required antennas and power supplies. When connected to the GLX-D Frequency Manager, GLXD4R receivers operate in the most spectrally efficient manner.

Features

Improves the RF performance of connected GLXD4R receivers
Increases channel count with more efficient frequency management
Distributes RF signal and power to six receivers
Cascade ports connect second frequency manager for up to 11 receivers
Consolidates antennas and power supplies for simpler setup
Mounts in standard 19 inch equipment racks
Supports remote antenna placement
All-metal construction

Hardware Connections

Connect each antenna to the antenna A and antenna B outputs on the frequency manager's 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 frequency manager.
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 GLX-D 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, which can happen if you set up multiple GLXD4R receivers without the frequency manager. Sharing a larger group of frequencies also improves RF reliability for receivers.

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.

Group	Channel Count (Number of Receivers)	Latency	Notes
A	6 typical, 9 maximum	4 ms
B	9 typical, 11 maximum	7.3 ms	Best group if you experience interference.

Linking Transmitters and Receivers

Tip: Turn on and link one transmitter and receiver pair at a time to prevent transmitters from linking to the wrong receiver.

After selecting a group using the first receiver, turn on the first transmitter. The blue receiver rf LED flashes as the transmitter and receiver form a link. The rf LED turns solid blue when the link is complete.
Turn on the second transmitter and repeat for each additional receiver/transmitter pair to finish linking.

Connecting Two GLX-D Frequency Managers

If using more than six receivers, use the cascade A and cascade B ports to connect two GLX-D Frequency Managers. Frequency managers can be cascaded once for a maximum of 11 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.
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. 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. Experiment 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.

Frequency Manager	Frequency Manager Port Number	Receiver Channel Display
Frequency manager #1	1	1
	2	2
	3	3
	4	4
	5	5
	6 (cascade)*	6*
Frequency manager #2	1	6
	2	7
	3	8
	4	9
	5	A
	6 (cascade)	B

*If using two frequency managers, this cascade port connects to the second frequency manager, so there is no receiver channel display.

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.
