2.1 Achieving the Best Performance
To achieve the best performance:
Use only good quality connection cables (we recommend Kramer high-
performance, high-resolution cables) to avoid interference, deterioration in
signal quality due to poor matching, and elevated noise levels (often
associated with low quality cables)
Do not secure the cables in tight bundles or roll the slack into tight coils
Avoid interference from neighboring electrical appliances that may adversely
influence signal quality
Position your Kramer VP-772 away from moisture, excessive sunlight and
dust
This equipment is to be used only inside a building. It may only be
connected to other equipment that is installed inside a building.

VP-772 - Overview
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
de-interlacing algorithms, and full up-and down-scaling of the video inputs
K-IIT XL™ Picture-in-Picture Image Insertion Technology for ultra-stable
picture−in−picture, picture−and−picture and split screen capability
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 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
mode) as well as HDTV and computer graphics resolutions with selectable
refresh rates
Selectable HDMI, VGA, YUV or CV on each DVI-U input and VGA or HDMI
on each DVI-I output
Audio-Follow-Video (AFV) and breakaway options

VP-772 –Overview

Advanced deinterlacing functions - including 3D comb filtering, film mode,
diagonal correction and motion detection
Multiple Aspect Ratio Selections
Built-in Proc-Amp with enhanced functions such as color correction, gamma,
dither and noise reduction
Embedded HDMI audio support as well as eight balanced stereo audio
inputs and two balanced stereo outputs
Input and output audio level adjustment and audio DSP functions
HDCP Compliance
In addition, the VP-772:
Features luma- and chroma-keying
Includes built-in test patterns for screen setup and alignment
Analyses the connected output’s EDID for optimal scaling
Provides input and output color space control
Supports HDMI deep color for outputs
Comes with an On-Screen Display (OSD) for easy setup and adjustment
Has a non-volatile memory that retains the settings
Supports firmware upgrade via USB (via memory stick)
Control your VP-772:
Directly, via the front panel push buttons
Via the Ethernet
By RS-485 (allowing future optional T-bar control)
Remotely, from the infrared remote control transmitter
By RS-232 serial commands transmitted by a touch screen system, PC, or
other serial controller
The VP-772 is housed in a 19” 1U rack mountable enclosure, with handles and rack
“ears” included, and is fed from a 100-240 VAC universal switching power supply.

VP-772 - Overview
3.1 HDCP Compliance for HDMI inputs
If an HDMI signal is HDCP protected, it can only appear on HDMI
outputs that are connected to HDCP compliant displays.
The VP-772 will not output a picture on an HDMI display that is not
HDCP compliant; instead it will show a green screen.
In the PiP mode (see Section 7.2), even if only one of the inputs is HDCP
protected, and is output to a non-compliant display, it will affect the
entire screen and turn it green.
When using a VGA output display, the screen will turn black.

VP-772 - Connecting the VP-772
5 Connecting the VP-772
Always switch off the power to each device before connecting it to
your VP-772. After connecting your VP-772, connect its power and
then switch on the power to each device.
You do not have to connect all the inputs and outputs, connect only
those that are required.
To connect the VP-772, as illustrated in the example in Figure 3, do the following:
1. Connect up to eight sources (for example, a PC, BluRay Disk Player,
Composite DVD player and so on) to the DVI INPUT connectors, according
to the Input OSD setup, see Section 6.2.
Use the ADC-DMA/5BF-1 and AD-DM/GF adapters provided with the package when
connecting a YUV, VGA or CV input, as required
2. Connect the audio input signals to the AUDIO IN terminal block connectors,
as required, see Section 5.2 (not shown in Figure 3).
3. Connect the PREVIEW OUT DVI connector to a DVI acceptor (for example,
an LCD display).
4. Connect the PROGRAM OUT DVI connector to a DVI acceptor (for
example, a projector).
Note that when high output resolutions (such as 4k2k@30) we
recommend that you use a DVI to HDMI cable (for example, the
Kramer C-HM/DM 6’ or 10’).
For lower resolutions you can connect the HDMI connector on a
device to the DVI connector on the VP-772 via a HDMI-DVI adapter
5. Connect the AUDIO OUT 1 and OUT 2 Terminal Block connectors to up to
two balanced analog audio acceptors, see Section 5.2 (not shown
in Figure 3).
6. If required, you can connect a PC and/or controller to the:
RS-232 terminal block (see Section 8.2.1)
Ethernet connector (see Section 8.2.2

VP-772 - The OSD Menu
6 The OSD Menu
The OSD menu lets you set the VP-772 operation parameters.
The OSD sub-menu operations appear in the OSD title, as shown in the example in
Section 6.1:
When in the main menu, the OSD title appears empty
Level 1 lists the main menu items
Level 2 includes the second hierarchy level, below level 1
Level 3 includes the third hierarchy level, below level 2
Level 4 includes the fourth hierarchy level, below level 3
Function (the fifth level), is the selectable parameter or numerical value and
can appear either under level 2, 3 or 4
6.1 OSD Menu Operation Example
In the example illustrated below, the Program Aspect Ratio is set to Best Fit as
illustrated in Figure 9 (see OSD menu in Section 6.4).

Note that:
We recommend that you press Enter to save the changes to the memory
immediately although exiting the menu saves the parameter to the memory
Data is saved per window and per input (to a dedicated input + window
memory), as applicable
The control buttons let you control the VP-772 via the OSD menu. Press the:
MENU button to enter the menu and exit the menu
button when in the OSD menu, to move to the previous level and change
menu settings in the OSD screen.
ENTER (or ) button to access sub-menu items
Arrow buttons to move through the OSD menu
or arrows to change settings
Note that when exiting the menu, all the changes are automatically
saved to the non-volatile memory.
The default OSD timeout for auto exit is set to 30 seconds and can be
changed (see Section 6.5).
Note that some items appear red on the OSD menu indicating that
they are disabled.
