RF sync for SpeechLine Digital Wireless

For the most efficient use of the RF spectrum in multi-channel applications of SpeechLine Digital Wireless, the receivers are able to synchronize with each other.

Use of the RF spectrum

One master receiver provides a transmission clock over the air to its followers in order to guarantee safe RF performance. Every RF group needs to have one master, which can be generated automatically or set manually.

Automatic RF Sync

We recommend the automatic RF sync mode for single-room installations with only one RF group.

For larger installations in multiple rooms with multiple RF groups, we recommend the manual RF sync mode (see Manual RF Sync).
