VP-725DS, Presentation Switcher / Scaler VP725DS VP725-DS



The VP-725DS are presentation scaler/switchers with multiple signal format sections with the VP-725DSA adding balanced stereo audio for each input. The unit has 5 sections: a 4x1composite video section, a 4x1 s-Video (Y/C) section, a 4x1 component video (YUV) section, a 4x1 computer graphics video section and a 2x1 DVI video section - that can be operated as unique individual switchers contained in one box. Also any one of the 18 inputs can be scaled to a single graphics or HDTV output resolution on the three scaled output connectors comprised of an HD-15F connector, 5 BNC connectors and a DVI connector simultaneously.

Typical Applications:

  • Projection systems in conference rooms, board rooms, auditoriums, hotels, and churches.

  • Any application in which high quality conversion and switching of multiple and different video signals to graphical data is required for projection and large display purposes.



  • K-Storm™ Scaling Technology – Kramer’s extremely high performance scaling technology. High quality 3: 2 and 2:2 pull down de-interlacing and full up and down scaling of computer graphics video input signals.

  • Fade-Thru-Black (FTB™) Switching - The video fades to black and then the new input fades from black for glitch-free and smooth switching. The output signal provides constant sync so the display never glitches.

  • K-ITT™ Picture-in-Picture Image Insertion Technology - Ultra stable picture-in-picture image insertion capability. Any video source can be inserted into a computer graphics video source and vice versa with positioning and sizing controls. A unique splitscreen mode (2 images side-by-side) is also available.

  • 6 Switchers in 1 - Five dedicated signal formats: a 4x1 Composite, 4x1 s-Video (Y/C), 4x1 Component (RGB/YUV), 4x1 Computer Graphics (HD-15F), and a 2x1 DVI-D (on a DVI-I connector). One 18x1:3 scaled output.

  • Scaled Computer & HDTV Outputs - A single output signal in 3 formats (HD-15, 3 BNCs, and DVI-D) simultaneously.

  • Multiple Computer Graphics Output Resolutions - including a user-defined output resolution with selectable refresh rates.

  • HDTV Output Resolutions - 480p, 720P and 1080i in component format on all 3 scaled outputs simultaneously with selectable refresh rates.

  • Audio (VP-725DSA) - Balanced stereo audio inputs for all 18 inputs plus balanced stereo audio outputs for all 5 dedicated signal format outputs and one for the scaled output.

  • Multi-Standard - PAL, SECAM, & NTSC (3.58/4.43)

  • Multiple Aspect Ratio Selections - 4x3 or 16x9, anamorphic, letter box, and user definable settings.

  • HDTV Compatible Component Input.

  • Built-in Time Base Corrector - Stabilizes video sources with unstable sync.

  • Multiple Color Space - Output RGB or YUV (Selectable).

  • Built-in Proc-Amp - Color, hue, sharpness, contrast, and brightness are set individually for each input.

  • Mic Input (VS-725DSA) - Condenser or Dynamic with talk over, mix and override controls.

  • Front Panel Lockout.

  • Freeze Frame.

  • Audio Mute.

  • Video Blanking - Blue or black screen.

  • Zoom (100% to 400%).

  • Flexible Control Options - Front panel buttons, IR Remote (with on-screen menus) & RS-232.

  • Worldwide Power Supply - 100-240V AC.

  • Standard 19” Rack Mount Size - 3U.
