Description:

In which band do SM and BETA Digital Wireless Systems operate?

SM and BETA Digital Wireless Systems are working in the 2.4 GHz ISM band. This band is license free and is not affected by any regulation change related to LTE /4G and wireless broadband. This band is used by other devices like Wi-Fi or Bluetooth, therefore an intelligent frequency management system is essential which is provided by Digital SM and Beta Wireless.

How should I setup the system?

  1. Switch on all devices working in the 2.4 GHz range you need during performance. Switch off all devices working in the 2.4 GHz range you do not need during performance.
  2. Switch on SM / BETA Digital Wireless receiver (GLXD4 or GLXD6).
  3. Decide, which performance level you want to set:
    • Group 1: Automatic Mode with backup frequencies (4.0 ms latency; up to 4 compatible systems if 2.4 GHz spectrum is completely free of traffic)
    • Group 2: Automatic Mode with backup frequencies (7.3 ms latency; up to 5 compatible systems if 2.4 GHz spectrum is completely free of traffic)
    • Group 3: Manual Mode without backup frequencies (7.3 ms latency; up to 8 compatible systems if 2.4 GHz spectrum is completely free of traffic)
  4. Switch on SM/Beta Digital Wireless transmitter (GLXD1 or GLXD2)
  5. Synchronize Receiver and Transmitter
  6. Let the digital wireless receiver scan for best frequency and start your performance.

 


GLX-D Firmware Update

Shure periodically updates device firmware to add features and improve system performance. There is a new firmware available which can be uploaded to this product. Please note that all systems need to operate on the same firmware, e.g. 2.0 for full functionality. To update your products please download the application and update devices to firmware version 2.0 or higher.

Tips to get the best performance of the system

  • Keep line-of-sight between receiver and transmitter. Recommended distance is 20–30 meters max.
  • Keep a short distance between transmitter and receiver - for example, place receivers on stage.
  • Avoid placing transmitter or receiver near metal or other dense materials.
  • Keep receiver further away from Wi-Fi access points, computers, or other active 2.4 GHz sources. Recommended distance is a minimum of 3 meters.
  • Avoid, if possible, heavy Wi-Fi traffic activities such as downloading large files.
  • Change all SM / Beta Digital Systems to Group 2, which is the most robust wireless group.
  • If there is a known strong source of Wi-Fi and you specifically want to use frequencies within a specific free Wi-Fi channel, use the following Group/Channel (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

How many musicians can use this system simultaneously?

Depending on the selected group and the Wi-Fi conditions, up to 4 compatible systems can be run in parallel under typical conditions and up to 8 if the 2.4 GHz spectrum is free of traffic.

This system was developed for perfect audio within operating ranges of 20 – 30 meters to be used for up to 4 systems simultaneously. If more systems are needed that cover a wider operating range, QLX-D Digital Wireless is recommended.

How is the operating range?

  • Indoor: Up to 30 m under typical conditions
  • Outdoor: Up to 20 m under typical conditions

How does the Automatic Frequency Management work?

  • The Digital Wireless System features LINKFREQ which is an Automatic Frequency Manager making it easy to rely on seamless, crystal-clear audio.
  • The receiver continuously analyses the available frequency spectrum.
  • The receiver and transmitter automatically link using the best set of available frequencies.
  • If interference occurs, the receiver and transmitter intelligently move together to the best open frequencies, without audio interruption.
  • No buttons to push or controls to adjust.

How can I recharge the batteries of the transmitter?

  • The Digital Wireless standard receiver (GLXD4) has a battery charging bay
  • In addition to that, Shure Digital Power Management offers multiple charging solutions such as car-, wall- or USB-chargers
    • Charge battery alone:
      • SBC902: USB battery dock charger (available separately)
