At the moment, multi-room support via the Stream Magic app is not possible.
There are however other services/software which can perform this in the meantime.
- AirPlay: When selecting a device via Airplay in various streaming services, you'll have the option to select more than one Cambridge Audio device for playback. This will sync the devices so they play the same audio at the same time.
- ROON: If you have more than one Cambridge Audio device set up as an endpoint in your ROON software, you can create a multiroom option or "ZONE" within ROON. Then, by selecting this zone,e you will play audio from ROON to these devices in sync.
- Google Cast: As your Evo One includes Chromecast Built-in, this will allow you to add the device to a Cast speaker group. Once added, you will be able to Cast audio from Chromecast-compatible apps to multiple speakers at the same time. More information can be found here.
