Password protection prevents unauthorized access to controls, making it the ideal solution for mobile wireless control of venues, conference rooms, hotel lobbies and any other installed sound environment where the operator may not have experience with audio mixing. Qu-Control offers simple configuration of up to five screens with up to 15 control ‘widgets’ each, for applications including background music source selection, master zone level, scene recall, or microphone paging. It provides an end user interface for wireless mobile control of the Qu digital mixers. Qu-Control is a customisable iOS app for iPod Touch, iPhone and iPad.
