By default the program starts in setup mode indicated by the "gear" icon on the right. In this mode all editing can be done.
Via the menu Mode selector the system can be put in show mode. In show mode selecting channels is not possible. Mute, standby, delay on/off functions need to be confirmed by the user. The gain slider changes its response to mouse input so that small changes can be made easily. Show mode is indicated by the "spotlights" icon on the right.
