This unit can switch any one of eight inputs to one computer graphics video, one unbalanced and one balanced stereo audio and one twisted pair output. It is designed to work with a family of Step-In modules: the SI-1VGA, SI-1VGAT and WSI-1VGA. These Step-in modules are part of Kramer’s Table Mount Solution Products, such as the line of TBUS models, which are mounted in or below conference room tables.

With the VP-81KSi, meeting attendees can connect the computer graphics video and audio from their laptops into the module located in a TBUS at their seat. The module is prewired to the switcher that is connected to the projector. Every attendee can make his laptop the active device on display by pressing a switch in the module.

The VP-81KSi is HDTV compatible and has a very high video bandwidth of 440 MHz
(-3dB) to ensure transparent performance for signals with resolutions up to WUXGA. It also includes Kr-isp™, Kramer’s innovative integrated sync processing technology.
Kr-isp™ restores the sync signal waveform to provide a sharp, stable image even when the sync level is too low. Additional features are mentioned in the user manual.

Larger virtual systems can be created by cascading eight VP-81KSi switchers to form a 57 input virtual switcher for use in a very large conference center installation.

The VP-81KSi switcher offers several very flexible control options including front panel buttons, remote step-in modules, RS-232, RS-485, Ethernet via a built-in web server, contact closure & IR remote control (remote is included). It has a worldwide power supply that operates on 100-240V AC, fits a standard 19” rack mount and includes a standard pair of rack mount “ears”.
