8x1 Computer Graphics Video & Stereo Audio Step-In Switcher

The VP81KSi is a high-performance analog step-in switcher for computer graphics video with resolutions up to WUXGA and unbalanced stereo audio signals. The VP 81KSi 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 works in conjunction with up to eight VGA Remote Control Step-in Modules including the SI-1VGA (for TBUS-10), SI-1VGAT (under the table) and WSI-1VGA (for standard TBUSes).

VP-81KSI features include:

  • High Bandwidth - 440MHz (−3dB), CAT 5 (Rec Out) up to WUXGA.

  • HDTV Compatible.

  • Kr-isp® Advanced Sync Processing - Ensures compatibility with a wide range of computers (even if the sync level is too low) by restoring the sync signal waveform.

  • Remote Step-In Switching - Up to 8 users, connected through SI−1VGA remote input/switching step−in modules, can each step in to switch the input to the local remote PC.

  • I-EDIDPro™ Kramer Intelligent EDID Processing™ - Intelligent EDID handling & processing algorithm ensures Plug and Play operation for analog systems.

  • Multiple Unit Cascade - Cascades up to 8 units to create a "virtual" switcher of up to 57 inputs.

  • Audio Switching Modes - Audio−Follows−Video (AFV) and audio breakaway switching.

  • Flexible Control Options - Front panel, remote step−in panels, RS−232 (K−Router™ Windows®−based software is included), RS−485, Ethernet via a built−in Web server, contact closure & IR remote (included).

  • Worldwide Power Supply - 100−240V AC.

  • Standard 19” Rack Mount Size - 1U. Rack "ears" included.
