GLX-D transmitters are powered by Shure SB902A lithium-ion rechargeable batteries. Advanced battery chemistry maximizes runtimes with zero memory effects, eliminating the need to discharge batteries prior to charging.
When not in use, recommended battery storage temperature is 10°C (50°F) to 25°C (77°F).
Note: The transmitter will not pass RF or audio signals when connected to the charging cable.
The following battery charging options are available:
The following LED states indicate battery status when the transmitter is connected to a charger:
Use the following table to determine approximate battery runtime based on the duration of charging time. Times shown are in hours and minutes.
Note: Batteries charge faster when using an AC powered charger versus a USB connection.
| AC Power Source Charging | USB Connection Charging | Transmitter Runtime |
|---|---|---|
| 0:15 | 0:30 | up to 1:30 |
| 0:30 | 1:00 | up to 3:00 |
| 1:00 | 2:00 | up to 6:00 |
| 3:00 | 4:00 | up to 11:30* |
*Storage time or excessive heat will reduce maximum runtime.
Note: GLX-D transmitters automatically power-off after approximately 1 hour to conserve battery life if the signal from a linked receiver is not detected.
Proper care and storage of Shure batteries results in reliable performance and ensures a long lifetime.
Important: Always fully charge a new battery before first use, in receiver if possible.
The number of segments illuminated on the meter indicates the remaining battery life for a linked transmitter:
① = > 30 min
② = > 2 hours
③ = > 4 hours
④ = > 6 hours
⑤ = > 8 hours
⑥ = > 10 hours
⑦ = > 11.5 hours
Note: The LEDs will cycle on/off while battery life is being calculated.
For ease of set up, frequencies are divided into groups to best match the channel requirements for your system.
Select the group by determining the total number of receivers in your system (channel count). All receivers in the system must be set to the same group.
| Group | Channel Count (Number of Receivers) | Number of Backup Frequencies | Notes |
|---|---|---|---|
| 1 | Up to 4 | 3 | Initial factory setting. |
| 2 | Up to 5* | 3 | Best multi-channel group if you experience interference. |
| 3 | Up to 8* | 0 | For large multi-channel systems. Only use Group 3 in controlled Wi-Fi environments because there are no backup frequencies to avoid interference. |
| 4 | 1 | 27 | Best single-channel group if you experience interference. |
*Environmentally dependent, 4 systems typical
See "Tips to Improve Wireless System Performance" section for additional information.
Note: Before beginning, turn off all receivers and transmitters. Turn on and set up each receiver/transmitter pair individually to prevent cross-linking.
Repeat steps 1-3 for each additional receiver and transmitter. Remember to set each receiver to the same group.
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.
Specific groups and channels can be assigned to the receiver instead of using the automatic scan function.
Note: Group 3 should only be used in controlled Wi-Fi environments to prevent interference from unexpected Wi-Fi devices.
Note: A double dash symbol-- displayed on the receiver screen during a channel scan indicates that there are no available channels within the selected group. Choose a group with more channels and repeat set up steps.
Use the manual linking option to change the transmitter linked to a receiver. A common use for manual linking is changing the linked transmitter from a bodypack type to a handheld type.
Link multiple transmitters to the same receiver to allow for instrument changes during a performance. Only one transmitter can be active at a time, otherwise the signals will interfere with each other.
After linking the transmitters, gain settings can be set and stored independently for each transmitter.
Important! Do not turn on and operate both linked transmitters at any time.
Turn off both transmitters before beginning.
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.
The challenge of 2.4GHz is that Wi-Fi traffic can be unpredictable. GLX-D meets these challenges in the following ways:
If you plan to use Wi-Fi during a performance, turn on Wi-Fi devices prior to turning on GLX-D and scanning for the best channel. GLX-D detects and avoids other 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.
Some environments are more difficult than others for 2.4 GHz wireless system performance. Additionally, body absorption has a greater impact in the 2.4 GHz spectrum, compared to the UHF spectrum. 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:
Note: Unlike analog TV band wireless which typically uses the same type of transmissions across manufacturers, all 2.4GHz wireless currently on the market use different variations of wireless transmission. These differences make it more difficult to mix and match 2.4 GHz from multiple manufacturers successfully, as can be done with TV band wireless solutions.
If you encounter interference or dropouts, try the following suggestions:
Note: GLX-D transmitters closer than 6 inches (15 cm) to other non-GLX-D transmitters may cause audible noise in that transmitter
The following tables list receiver channels, frequencies, and latency for each group:
