VP-724XL, ProScale™ Digital Switcher / Scaler VP724XL VP724-XL



The VP-724xl is an 8-input scaler/switcher with unbalanced stereo audio. It scales any composite, s-Video (Y/C), component video (YUV), DVI video or computer graphics video signal up or down to a selectable graphics or HDTV output resolution and provides glitch-free switching between sources through FTB™ (fade-thru-black) switching technology.

Typical Applications:

  • Projection systems in conference rooms, boardrooms, auditoriums, hotels and Churches

  • Production studios, rental and staging

  • Any application where high quality conversion and switching of multiple and different video signals to graphical data signals is required for projection 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 or vice versa with positioning and sizing controls. A unique Split-Screen mode (2 images side-by side) is also available

  • 8 Video Inputs - including 2 15-pin HD computer graphics video inputs.

  • Dual Output Connectors - 2 computer graphics video outputs on 15-pin HD connectors.

  • HDTV Output Resolutions - 480p, 720P and 1080i in component format on the HD-15 output connectors with selectable refresh rates.

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

  • Multi-Standard Video Signal Compatibility - PAL, SECAM, & NTSC (3.58/4.43).

  • Multiple Aspect Ratio Selections.

  • HDTV Compatible Component Input.

  • Companion AFV (audio follow video) Stereo Audio for Every Input.

  • Built-in 5 Watt RMS per Channel Audio Amplifier with Speaker Output connectors

  • 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.
