DVI (HDCP) ProScale Presentation Matrix Switcher/Dual Scaler


The VP-772 is an eight-input high-quality 4K UHD (3840x2160) dual scaler with special effect transitions for the rental and staging and the live events market and for other applications where a dual-scaler is needed. It features DVI-U inputs (including analog, DVI and HDMI support) and stereo balanced audio signals. The unit scales and processes the selected video and audio inputs, and outputs to two independent DVI-I outputs (program and preview) together with two balanced stereo audio outputs.

Features & Benefits

  • Output Resolutions - Up to UHD (3840x2160) for single output mode (non-dual scaler); HDTV and computer graphics resolutions with selectable refresh rates.
  • Multi-Format Operation - Selectable HDMI, VGA, YUV or CV on each DVI-U input and VGA or HDMI on each DVI-I output.
  • Embedded HDMI Audio Support - As well as eight balanced stereo audio inputs and two balanced stereo outputs.
  • PixPerfect Scaling Technology - Kramer's extremely high performance, state-of-the-art scaling technology with extensive high-quality pull-down and de-interlacing algorithms, and full up-and down-scaling of the video inputs.
  • K-IIT XL Picture-in-Picture Image Insertion Technology - Ultra-stable picture-in-picture, picture-and-picture, and split screen capability. Any video source can be inserted into or positioned next to any other video source with full window positioning and sizing controls.
  • Seamless Video Switching - With cuts or built-in special effect transitions, including horizontal, vertical, diagonal circle and chessboard wipes, cross-fading, and more.
  • Dual Scalers - For "live" seamless transitions from one source to another with two independent outputs: a PREVIEW OUT and a PROGRAM OUT. The PREVIEW output, including an OSD menu for making adjustments, is used for determining how the scaled output looks before displaying live during a presentation.
