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 setup as an endpoint in your ROON software, you can create a multiroom option or "ZONE" within ROON. Then by selecting this zone you will play audio from ROON to these devices in sync.
