Tips to Improve Wireless System Performance
If you encounter interference or dropouts, try the following suggestions:
1. Place receiver at least 3 meters (10 feet) away from Wi-Fi access points, computers, or other active 2.4 GHz sources.
- Avoid heavy Wi-Fi traffic activities such as downloading large files or viewing a movie.
- Turn on any Wi-Fi prior to turning on GLX-D and scanning for the best channel.
2. Reduce transmitter-to-receiver distance by placing receivers on stage or above the audience with a clear line of sight to the transmitter.
- Move receiver to the top of the equipment rack for a clear line of sight.
- Mount antennas remotely to place closer to transmitters and improve RF reliability if receivers cannot be moved closer.
- Make sure people do not block the line of sight between receiver and transmitter.

Additional Tips

• Do not place competitive 2.4 GHz receivers near GLXD4R receivers.
• Connect more than two GLXD4R receivers to a GLX-D Frequency Manager to improve RF reliability.
• Scan for the best available channel by pressing the channel button.
• Keep transmitters more than 2 meters (6 feet) apart. This is less critical with shorter receiver-to-transmitter distances or if receivers are connected to a
GLX-D Frequency Manager.
Note: If transmitters are within 6 inches of non-GLX-D transmitters or microphone cartridges, audible noise is possible.
• Move transmitter and receiver away from metal or other dense materials.
• During sound check, mark trouble spots and ask performers to avoid those areas.
• If there is a strong source of Wi-Fi and you specifically want to use frequencies within that Wi-Fi channel, use the following Group/Channel combina-
tions (best option listed first):
- Wi-Fi 1: Group 3/Channel 8, Group 3/Channel 4
- Wi-Fi 6: Group 3/Channel 7, Group 3/Channel 5
- Wi-Fi 11: Group 3/Channel 2, Group 3/Channel 1
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.
