Multi-platform keyboard, video, mouse & audio switch, providing data security and pristine video switching.

One of the most powerful KVM switches targeted at mission critical applications ever built, the K4vu is the only sensible choice for applications requiring the highest standards of performance. Up to four computers can be controlled from a single keyboard, mouse and monitor(s) and four sources of audio can be mixed or switched into one audio device.

Dual head sources are fully supported on each of its four channels, and the video signals can be either analogue or digital with complete management of monitor information. State of the art design gives outstanding video quality, making the K4vu perfect for digital media applications.

The K4vu is specifically designed to enhance system security by preventing channel cross-talk or key-stroke recording. Unlike cheaper less reliable switches, the K4vu firmware can be upgraded at any time, ensuring you always have the latest features and best performance. If you need a totally reliable, secure keyboard, video and mouse switch for a mission critical application, the Amulet Hotkey K4vu is the only safe option.
