  • Page 41: Active Channel

    NOTE: The Autoselect feature means that when the incoming source changes in the active channel, the projector automatically selects and switches to the source file within that channel that most closely matches the incoming source's parameters. The channel selected must have a source file set up to handle the type of incoming video or graphic source.
