    There is one central idea underlying the Matrix System ® from MTi — that you should be able to demonstrate any and all of the components in your System as they were meant to be demonstrated, in any combination, with minimum effort. We have engineered the logic into our switching systems to give you maximum flexibility and selling power.

  • Page 14: Passive Switching

    Switching Modules can be added and assigned the same selection number. Passive Switching All MTi switching products are passive switching systems, which do not affect in any way the audio/video signal that is being switched. This ensures that any audio or video component being demonstrated with one of our systems exhibits its true range of capability.
