The Syntrolux Express is a machine used in the music video for "Using You" by Mars Argo. It was in testing and seemed to have been created to examine the emotional response of whoever is listening to the song currently being played. The song is played through a large number of speakers at once, forcing a reaction to everyone who can hear it unless they're wearing noise cancelling headphones. Mars Argo and Titanic Sinclair are the only people who are immune to these effects. After the song ends, the machine prints statistics and information on a long sheet of paper. This includes the specific emotions they felt, and how they were built up throughout the duration of the song.
