This matrix switch enables the broadcast of multiple computers audio & video outputs to multiple displays. Any input can be broadcast to any or all of the outputs; simultaneously display an image from any connected source to any connected monitor. For example, if you connect four computers & four monitors, you can show the same or a separate image on each monitor. The 3.5 mm audio outputs can drive either speakers or earphones. Built-in video signal enhancement lets you place monitors up to 50 meters feet away while maintaining your video quality. From use in test bench facilities, data centers & help desks to video broadcasting, the Tru Link video/audio matrix switch delivers both performance & value.
