Multiple Receiver Systems If several channels of wireless audio are needed, up to 8 GLX-D receivers can operate simultaneously in the 2.4 GHz spectrum. For ease of set up, available frequencies are divided into three groups based on the number of receivers supported. All receivers in the system must be set to the same group. To select a group, determine the total number of receivers in the system (channel count), and then select the appropriate group. Note: To maximize the number of receivers on-air, Group 3 does not offer backup frequencies. Group 3 should only be used in controlled Wi-Fi environments to prevent interference from unexpected Wi-Fi devices. Group Channel Count Backup Frequencies Available? Notes 1 Up to 4 Yes Initial Factory Setting. 2 Up to 5 Yes Best Group to use if you experience interference. 3 Up to 8 No Only use Group 3 in controlled Wi-Fi environments because there are no backup frequencies to avoid interference. Note: If you experience interference, reduce transmitter to receiver distance and set all GLX-D systems to group 2, which is the most robust wireless group. See "Tips to Improve Wireless System Performance" section for additional information. Manually Linking a Transmitter to a Receiver Use the manual linking option to change the transmitter linked to a receiver. For example, changing the linked transmitter from a bodypack to a handheld. 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 light will illuminate when a link is established.

Repeat steps 1-3 for each additional receiver and transmitter. Remember to set each receiver to the same group. 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.

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.

Note: Dashes appearing on the group and channel display during a channel scan indicate that frequencies are not available in the selected group. Choose a group that supports more receivers and repeat the set up steps. group channel -- --12

2.4 GHz Spectrum Overview

GLX-D operates within the 2.4GHz ISM band which is utilized by Wi-Fi, Bluetooth, and other wireless devices. The benefit of 2.4GHz is that it’s a global band that can be used anywhere in the world, license free. Overcoming the Challenges of 2.4GHz The challenge of 2.4GHz is that Wi-Fi traffic can be unpredictable. GLX-D meets these challenges in the following ways:

• Prioritizes and transmits on the best 3 frequencies per channel (choosing from a pool of 6 frequencies across the 2.4GHz band)

• Repeats the most important information such that one frequency can be taken out entirely without audio interruption

• Continuously scans during usage to rank all frequencies (both current and backup frequencies)

• Seamlessly moves away from interference to backup frequencies without audio interruption Coexisting with Wi-Fi GLX-D avoids continuous Wi-Fi traffic by scanning the entire 2.4GHz environment and selecting the 3 best frequencies to transmit on. The result of this is reliable performance for your GLX-D wireless system as well as avoiding Wi-Fi transmissions which may be important as well. “Bursting” Wi-Fi is harder to detect as it is periodic; however, because GLX-D repeats the most important information, even bursts at very high-levels don’t have an effect on your audio performance. Challenging Wireless Environments Some environments are more difficult than others for 2.4 GHz wireless system performance. The simplest solution in many cases is to reduce the transmitter to receiver distance such as placing the receivers on the stage with a clear line of sight. Challenging environments include:

• 3 or more GLX-D receivers in use

• Strong Wi-Fi presence

• Non-Shure 2.4 GHz systems in use Tips and Methods to Improve Wireless System Performance If you encounter interference or dropouts, try the following suggestions:

• Scan for the best available channel (press the channel button)

• Reposition the receiver so there is nothing obstructing a line of sight to the transmitter (including the audience)

• Change all GLX-D systems to Group 2, which is the most robust wireless group

• Keep the transmitter and receiver more than 2 meters (6 feet) apart

• Keep transmitter to receiver distance within 60 meters (200 feet) - place receivers on-stage within line of sight if possible

• Remove or relocate nearby sources of wireless interference, such as Wi-Fi devices or hotspots, cell phones, two-way radios, computers, media players, and digital signal processors

• Disable non-essential Wi-Fi/bluetooth devices and avoid heavy Wi-Fi traffic activities such as downloading large files or viewing a movie.

• Locate GLX-D receivers away from non-Shure 2.4 GHz receivers

• Avoid placing transmitter and receiver where metal or other dense materials may be present

• Move the receiver to the top of the equipment rack

• Recharge or replace the transmitter battery

• Keep transmitters more than 2 meters (6 feet) apart - this is less critical at shorter receiver to transmitter distances Note: If transmitters are within 6 inches of non-GLXD transmitters or microphone cartridges, audible noise is possible.

• During sound check, mark trouble spots and ask presenters or performers to avoid those areas
