The average boardroom, conference room or training room has over 50 parts from 14 different manufacturers.  Even though the projector is often one of the most expensive components generally found in a high-quality presentation system, it’s not the key component.  Nor are the speakers, the
                     computer, the microphones, or
                     any other individual hardware
                     component. Ease of use is what
                     truly defines an excellent system. 
                     The Control System's User
                     Interface is what makes a system
                     easy to use and is therefore the
                     most significant part.  Without
                     this, any combination of video
                     and audio components will not
                     make up a successful
                     presentation environment.
