The VP-81KSi, with up to 8 Step-in modules, uses external modules to switch between inputs.

Kramer Electronics is pleased to introduce the highāˆ'performance VP-81KSi, an analog Step-in switcher for computer graphics video. The 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. The VP-81KSi 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 include: audio-follow-video (AFV) switching and an audio breakaway option that switches video and audio channels independently; DDC (Display Data Channel) communication between the selected input and output on pins 12 and 15 of the 15-pin HD connector; Kramer's I-EDIDPro™ intelligent EDID processing algorithm that ensures plug and play operation for analog systems; a volume control for the audio inputs; a standard 15-pin HD output connector and a CAT 5 output for compatible Kramer twisted pair receivers to provide long distance signal transmission.

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."

The VP-81KSi sells in the United States at a list price of $1295.00. The VP-81KSi is currently in stock and available from Kramer Electronics sales companies around the world. Complete product information can be found at
