RF Zone Settings
RF zones represent physical locations. Depending on how far apart your RF zones are from each other, you can have finer control over the settings between them.
RF zones detect and manage 2 potential sources of interference: channel-to-channel and intermodulation products.
- Channel-to-channel interference: Happens when one transmitter’s frequency is too close to the frequency of another.
- Intermodulation products: Small RF spikes that are a by-product of modulation and can potentially cause interference. Also called “intermods,” these are extra frequencies that take up space in your spectrum.Note:For more information on intermodulation distortion, see http://www.shure.com/americas/support/find-an-answer/what-is-intermodulation.
There are 3 different RF zone configuration settings you can choose from based on the distance between your zones. These settings appear as checkboxes in the zone manager ( ).
| How Close are the 2 RF Zones? | RF Zone Setting (Blue box = channel spacing; fuchsia box = intermodulation spacing) | Benefits | Considerations |
|---|---|---|---|
| Part of the same RF environment |  | Lowest chance you’ll encounter interference from your other devices | If you have too many devices, WWB might not be able to find enough frequencies |
|  | More frequencies than if all devices were in one zone | If intermods from other RF zones are present, there's a risk of interference |
| Far apart enough that you can reuse frequencies without worrying about interference |  | Higher number of frequencies | Ensure your RF zones are far enough apart that you are not at risk for channel-to-channel interference |
