The KanexPro 1x4 VGA is an ultra-fast active switcher with four input, one output, with stereo audio, which enables the next generation of auto-switching between four computers with stereo audio to an interactive whiteboard or a projector. It supports analog video signals such as RGBHV, RGBS, RGsB, RGBHVS and high-resolution signals up to QUXGA (3200x2400@60Hz) including 1080p/60.

In addition, multiple VGASW4APA switchers can be daisy-chained using high-resolution VGA cables to create a multi-user presentation system. Also delivers various control options such as RS-232, manual switching through front-panel buttons and volume control.

As an added feature, audio-breakaway is also supported, which can be controlled by RS-232 or volume control buttons for the corresponding video signal when switched between the four inputs. The KanexPro 1x4 VGA auto-switcher is ideal for classroom, conference and control room applications where high-resolution VGA switching with audio is critical.
