The VP-81Kfeatures:

•Very high video bandwidth, ensuring transparent UXGA performance

•Audio-follow-video (AFV) in which all operations relate to both the video and the audio channels, or audio breakaway option, in which video and audio channels switch independently

•Volume control

•DDC (Display Data Channel) communication between the selected input and output 1 high-density 15-pin HD connectors on pins 12 and 15

•KR-ISP™ technology, innovative integrated sync processing that lets you achieve a sharp, stable image even when the sync level is too low, by restoring the sync signal waveform

•The cascade of up to eight units with control from a PC or serial controller

•Automatic switching mode (as well as the regular switching mode), automatically switching to the lowest number input when that input is connected and active

For example, if INPUT 6 is currently selected and connected and then INPUT 4 receives an active signal, the VP-81K automatically switches to INPUT 4.
