The K4vu is a multi-platform keyboard, mouse, digital video and audio switch. It allows up to four computers to be controlled from a single keyboard, mouse and monitor and will mix or switch four sources of audio to one pair of powered speakers. It is designed for professional use in any 'business / mission critical' environment where reliability is paramount and keyboard or mouse lock-ups cannot be tolerated.

The K4vu fully supports dual head video sources on each of it's four channels. The video signals can be either analogue or digital and the K4vu video switching system manages all monitor DDC (data channel) information ensuring that connected computers always have accurate data regarding the monitors attached to the K4vu video outputs.
