All the Sony audio devices have multiple sound sources for multi-zone environments. These include:
- External sources, such as HDMI or analog inputs.
- Internal sources, such as the FM Tuner and USB.
- Remote sources, such as DLNA, Phones, Google Cast, Spotify, AirPlay, or Bluetooth.
The Sony DN1080 and some other receivers also have multiple outputs, each of which is called an output zone. The DN1080 has 3 possible zones: MainZone, Zone2, and HDMI Zone. In the Audio Control API a zone is usually identified by a number. Such as zone=1 for the MainZone, zone=2 for Zone2, and so on.
The MainZone is the primary speaker output. All source components are in it, and it provides multichannel sound.
Additional zones can be used to play music in other rooms, independent of what is playing in the MainZone or other zones. Extra zones can have some limitations. On the DN1080, for example, Zone2 provides line-level stereo audio output for use with a separate power amplifier and the HDMIZone allows for watching video content from different sources in two zones simultaneously. For more information, see the instruction manual of the receiver.
