Theatre Techniques Incorporated, a Connecticut manufacturer of stage lighting controls from the 1970s.
Particularly notable in that it was formed by disciples of George Izenour at Yale-- Jim Read (currently president of ASTC), Dennis Carnine, and Fred Lindauer (now with Robert Juliat). TTI's signature products such as two-scene consoles and 6-channel dimmer packs were basic improvements on the 1960s Century Edkotron system. They used the same single-handle autotransformer crossfader, and a similar integrating circuit on the dimmer control input. Interestingly, just as Izenour missed the need for a crossfade, split, dipless, so did the Edkotron and TTI systems.
LMI stepped in to fill the breach, and that was the end of TTI.
