Zones

Zones can be used to play back different audio and video to multiple areas. Some x to 1 sound cards can be used to split audio into x/2 different zones.

Add a Zone

Under the Player menu, choose "Zones", then "Add Zone"

Configure a Zone

Your new zone will appear under Playing Now. Click on it and use the standard options to select a sound device. (Each zone has its own device.)

A DLNA Renderer can also be a zone.

Play to a Zone

Select content and drag it to the zone. Or just click on the zone, then play.

Switching Zones

Ctrl-T will "toggle" zones. Or you can click on the zone you want to control under Playing Now.

More

Right click on the zone under Playing Now for more options.

Listener explains this well in this post on Interact.
