Multiple StageDirector screens can be used so that more than one screen can be displayed during a performance, where all screens are 'controlled' by the main StageDirector device. The additional screens (StageDirector box, or other screens) are wirelessly networked to the main or master StageDirector device.
For Karaoke, the multiple screens can be used to display the performance lyrics, so that the main device displays titles to choose from, and the additional screen displays lyrics.
