3 Overview
The Kramer VP-772 is an eight input high quality 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 VP-772
can also be configured as 4K single output scaler. The VP-772 scales and
processes the selected video and audio inputs, and outputs to 2 independent DVI-I
outputs (Program and Preview) together with two balanced stereo audio outputs.
The VP-772 features:
Pix Perfect™ Scaling Technology - Kramer’s extremely high performance,
State-of-the-Art scaling technology with extensive high-quality pull-down and

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 OUTPUT and a PROGRAM
OUTPUT. The PREVIEW output—including an OSD menu for making
adjustments—can be used to determine how the scaled output will look
before being displayed live during a presentation
Features 8 PREVIEW input buttons for switching a selected input to the
PREVIEW output and 8 PROGRAM input buttons for switching a selected
input to the PROGRAM output
Output Resolutions –UHD (3840x2160) resolution (in the Single Window
