2 VP-771 - Getting Started
2 Getting Started
We recommend that you:
•Unpack the equipment carefully and save the original box and packaging
materials for possible future shipment
•Review the contents of this user manual
Go to http://www.kramerelectronics.com to check for up-to-date
user manuals, application programs, and to check if firmware
upgrades are available (where appropriate).
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-771 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.
2.2 Safety Instructions
Caution: No operator serviceable parts inside the unit
Warning: You use only the power cord that is supplied with the
unit. Do not open the unit. High voltages can cause
electrical shock! Servicing by qualified personnel only.
Warning: Disconnect the power and unplug the unit from the wall
before installing

4 VP-771 - Overview
3 Overview
The Kramer VP-771 is a high quality presentation switcher and scaler. It accepts
one of nine inputs: a component video on RCA connectors, a DisplayPort (DP)
signal on a DisplayPort connector, an SDI signal on a BNC connector, two
computer graphics signals on 15-pin HD connectors, two composite video signals
on RCA connectors, and two HDMI signals on HDMI connectors. It scales the
video, embeds the audio, and simultaneously outputs the signal as follows: to the
HDMI output, to the computer graphics output, to the SDI output and to a DGKat TP
output, together with a digital audio output and an unbalanced stereo audio output.
COMPONENT VIDEO is also known as Y, Pb, Pr, or Y, Cb, Cr or YUV; compatible with both
SD and HD component
The VP-771 Presentation Switcher / Scaler features:
•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
•State-of-the-art video processing technology, with the highest quality de-
interlacing, noise reduction, and scaling performance for both standard-
definition and high-definition signals
•K-IIT XL™ Picture-in-Picture Image Insertion Technology - Ultra stable
picture−in−picture, picture−and−picture and split screen capability, or fully
customizable windows’ size and position control: any source can be inserted
into or positioned next to any other source and resized as desired
•Ultra Fast Fade-Thru-Black (FTB™) Switching - Video switching transitions
are clean and ultra-fast. The video fades to black and the new input fades
from black for smooth, glitch-free switching. The output signal provides
constant sync so the display never glitches
•Advanced deinterlacing functions - including 3D comb filtering, film mode,
diagonal correction and motion detection
•Scaled Outputs - HDMI, computer graphics, SDI output and a DGKat TP
output simultaneously
•Output Resolutions – HDTV and Computer Graphics up to 2K and
1080p/UXGA with selectable refresh rates

VP-771 – Overview 5
•Multiple Aspect Ratio Selections – Follow input, follow output, best fit,
letterbox, and user definable settings
•Multi-Standard SDI support - SDI (SMPTE 259M), HD-SDI (SMPTE 292M)
and 3G HD-SDI (SMPTE 424M)
•Max. Data Rate - 3Gbps (3G HD-SDI).
•Looping 3G HD-SDI Input
•SDI channeling, letting you select one active audio signal and three
bypassed signals from eight embedded stereo audio channels
•Multi-Standard Video support - NTSC (3.58/4.43), PAL (M/N/60) and SECAM
•Built-in Time Base Corrector - Stabilizes unstable video sources
•Built-in Proc-Amp with enhanced functions such as color correction, gamma
and dither
•Input and output audio level adjustment
•Digital (S/PDIF) and unbalanced stereo audio inputs and outputs, with
microphone talkover or microphone mix
•Built-in 2x10W power amplifier with speaker output connectors
•Automatic detection and selection of the HDMI and DP embedded audio.
The VP-771 automatically outputs the signal from the HDMI and DP
embedded audio inputs or performs an analog takeover to output the
respective analog audio input
•Selectable Power Save modes for energy efficient usage
•HDCP Compliant - The HDCP (High Definition Content Protection) license
agreement allows copy-protected data on the HDMI input to pass only to the
HDMI output
In addition, the VP-771 Presentation Switcher / Scaler:
•Includes luma keying via the PiP window
•Advanced EDID management per input
•Analyzes the EDID of a selectable Master connection to one of the outputs
•Supports picture zooming both on main and PiP window from 100% to
1600%, including separate V and H sharpness control

6 VP-771 - Overview
•Provides input and output color space control
•Supports HDMI deep color for inputs and output
•Features vertical Keystone operation
•Comes with an On-Screen Display (OSD) for easy setup and adjustment,
accessible via the IR remote control and via the front-panel buttons
•Has a non-volatile memory that retains the last settings used
•Supports firmware upgrade via RS-232 and Ethernet
Control your VP-771:
•Directly, via the front panel push buttons
•By RS-232 serial commands transmitted by a touch screen system, PC, or
other serial controller
•Remotely, from the infrared remote control transmitter
•Via contact closure remote control switching
•Via the Ethernet (optionally via the Web pages)
The VP-771 is housed in a 19” 1U rack mountable enclosure, with rack “ears”
included, and is fed from a 100-240 VAC universal switching power supply.
3.1 HDCP Compliance
If an HDMI signal is HDCP protected, it can only appear on HDMI
and DGKat outputs that are connected to supported HDCP
compliant displays.
The VP-771 will not output a picture on a display that is not HDCP
compliant as well as on the SDI/PC outputs; instead it will show a
black screen.
In the dual window display 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 black.

VP-771 – Overview 7
3.2 15BAbout the Power Connect™ Feature
The VP-771 can power the receiver on the DGKat output when the devices are
within 90m (270ft) of each other. The Power Connect™ feature applies as long as
the cable can carry power and the distance does not exceed 90m on standard TP
cable. For longer distances, heavy gauge cable should be used (TP cable is still
suitable for the video/audio transmission, but not for feeding the power at these
distances).
3.3 16BUsing Twisted Pair Cable
Kramer engineers have developed special twisted pair cables to best match our
digital twisted pair products; the Kramer: BC-DGKat524 (CAT 5 24 AWG), the
Kramer: BC-DGKat623 (CAT 6 23 AWG cable), and the Kramer: BC-DGKat7a23
(CAT 7a 23 AWG cable). These specially built cables significantly outperform
regular CAT 5 / CAT 6 / CAT 7a cables.

5 Connecting the VP-771
Always switch off the power to each device before connecting it to
your VP-771. After connecting your VP-771, 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-771, as illustrated in the example in Figure 3, do the following:
1. Connect an HDMI source (for example, a DVD player) to the HDMI 1 IN
VIDEO INPUT connector.
Alternatively, you can connect the DVI connector on the DVD player to the HDMI
connector on the VP-771 via a DVI-HDMI adapter. You can connect the audio signal via
the AUDIO IN HDMI 3.5mm mini jack, or use the embedded audio
2. Connect a computer graphics source to the PC 1 IN VIDEO INPUT 15-pin
HD connector.
3. Connect a component video source (for example, a component DVD player)
to the COMP PR, PBand Y, VIDEO INPUT RCA connectors.
4. Connect a composite video source (for example, a composite video player)
to the CV VIDEO INPUT RCA connector.
5. Connect a DisplayPort video source (for example, a computer graphics
source) to the DISPLAYPORT connector.
6. Connect the audio input signals to the AUDIO IN connectors (3.5mm mini
jack and RCA connectors), as required (not shown in Figure 3).
7. Connect an SDI source (for example, an SDI digital camera) to the SDI IN
BNC connector.
8. Connect the SDI LOOP BNC connector to an SDI monitor (for example, an
SDI display).
