5.4 Recommended Connection Schemes

Scenarios

Connection Schemes

Using One Transmitter with No more than two receivers:

Multiple Receivers

It is recommended to disable Broadcast mode, link in

Control mode, and set the SDR channel to AUTO.

Two receivers in Control mode should maintain a distance of more than 0.3 meters from each other.

More than two receivers: It is recommended to enable Broadcast mode and manually select a channel. You can start by connecting one receiver and, based on its channel quality indicator, prioritize channels with a lower number that offer superior quality.

Using Multiple Transmitters with Multiple Receivers

Each transmitter is paired with no more than two receivers: It is recommended to disable Broadcast mode, link in Control mode, and manually select a channel.

Receivers in Control mode should maintain a distance of more than 0.3 meters from each other.

Each transmitter is paired with more than two receivers: It is recommended to enable Broadcast mode and manually select a channel. You can start by connecting one receiver and, based on its channel quality indicator, prioritize channels with a lower number that offer superior quality. Additionally, ensure the channels for different transmitters are staggered to avoid using the same or adjacent channels.
