What are Groups and Channels?

To minimize interference, Shure wireless systems organize RF bands into predefined groups and channels. A group is a set of compatible frequencies within a frequency band. A single frequency within a group is a channel. Tune a receiver and transmitter to the best available channel within its group to set up your system.

Note: Because groups are band-dependent, some systems don't have multiple groups. Single-group bands have the same RF performance as those with multiple groups.

All receivers in the same band should be set to the same group. You can set them manually, or use the Guided Frequency Setup to walk you through the process.

Connect all the receivers in your system using Ethernet cables. For best results, use a network switch when connecting 3 or more receiver units.

Important! To avoid interference, before you begin:

Turn off all transmitters for the systems you are setting up. This prevents them from interfering with the frequency scan.

Turn on the following devices so they are operating as they would be during the presentation or performance. This will allow the scan to detect and avoid any interference from these devices:

  • Configured wireless systems or devices
  • Computers
  • Large LED panels
  • Effects processors
  • CD players

Using the Guided Frequency Setup

Set up a new system:

  1. Push the control knob on the receiver and select 1. Frequency Setup > 1.1 Guided Frequency Setup.
  2. Select Initialize My System and push the control knob to continue.
  3. Turn off all transmitters you plan to use with your system.
  4. Select start scan.
  5. After the scan is done, push the control knob to assign frequencies to the receiver.
  6. Turn on the transmitter you plan to use with this receiver.

  3. To change the group, rotate the control knob to select G:, push to select, rotate to change the number, push again to confirm.
  4. Select start scan.
  5. After the scan completes, push the control knob to apply the receiver channel.
  6. Turn on the transmitter you plan to use with this receiver.
  7. Align the infrared (IR) port on the transmitter with that on the receiver, and push the sync button.
  8. Once the sync is complete, the system is ready for use.

Manual Frequency Selection

To manually adjust group, channel or frequency:

  1. Select 1. Frequency Setup > 1.4 Manual Frequency Setup from the receiver menu.
  2. Use the control knob to select and adjust the group (G), channel (C), or frequency (MHz).
  3. Select apply and push the control knob to save.

Sound Check and Gain Adjustment

Navigate to the receiver's Gain screen to test the transmitter at performance levels. Adjust the gain to keep the audio indicator within the optimal range. Reduce the gain if there is audible distortion of the audio.
