It is becoming harder and harder to make an impression on visitors to trade fairs and to direct their attention to one's own brand. New technologies - with their numerous audio and video effects - play an increasing role here. And, this includes proper installation. Therefore, there is a requirement to centrally control content that originates from a variety of different source devices and is displayed on multiple different output devices. Through the increasing size of modern presentation rooms at events and trade fairs, being able to bridge large distances is becoming increasingly important. The modular AV matrix switch meets these demands by allowing multiple AV data signals to be controlled simultaneously and in parallel from a wide range of source devices, with different video interfaces. These output signals can then be effectively distributed over large distances of up to 100m.
