# Select a channel and URLs for Kaltura webcasting events

*Applies to: Pearl-2, Pearl Mini, Pearl Nexus.*

You can select which Pearl device channel is used for scheduled and ad hoc webcasting events. Optionally, you can stream the event to a secondary backup stream URL.
When a webcasting event is scheduled in Kaltura or started from Pearl device as an unscheduled ad hoc event, the stream URL and other event settings are sent to Pearl device. The Kaltura ingestion settings are applied automatically to Pearl device.
When you create a Kaltura webcasting event on Pearl device, you have the option to use the primary and backup URLs supplied by Kaltura for the stream or to choose a stream destination that is created locally for the channel on Pearl device. Alternative streaming destinations must already be configured for the channel being webcast. Select the **Auto** option to use the primary and backup URLs supplied by Kaltura. Auto is the default setting.
Ensure that you have selected the channel on Pearl device that you want to use for your scheduled webcasting event well in advanced of the event start time. The first channel on Pearl device is selected by default.
When it's time for the scheduled webcasting event to start, Pearl device automatically sends an RTMP (or RTMPS) stream to the primary URL associated with that event. If you've enabled the backup stream, Pearl device sends an RTMP stream to both the primary URL and the secondary backup URL associated with that event. If the primary URL stream fails for any reason, Kaltura automatically switches over to the backup URL.
