VP-778 - 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 www.kramerav.com/downloads/VP-778 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 VP-778 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:
There are no operator serviceable parts inside the unit
Warning:
Use only the power cord that is supplied with the unit
Warning:
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

2.3 Recycling Kramer Products
The Waste Electrical and Electronic Equipment (WEEE) Directive 2002/96/EC aims
to reduce the amount of WEEE sent for disposal to landfill or incineration by
requiring it to be collected and recycled. To comply with the WEEE Directive,
Kramer Electronics has made arrangements with the European Advanced
Recycling Network (EARN) and will cover any costs of treatment, recycling and
recovery of waste Kramer Electronics branded equipment on arrival at the EARN
facility. For details of Kramer’s recycling arrangements in your particular country go
to our recycling pages at www.kramerav.com/support/recycling.

VP-778 - Overview
3 Overview
VP-778 is an 8 Input ProScale™ Presentation Matrix Switcher/Dual Scaler with
seamless video cuts and 4K30 UHD output support. VP-778 can be configured as a
single 4K output (4K@30 UHD (3840x2160)) or dual HD scaler with full PIP
capabilities.
The unit has 4 HDMI inputs; 2 universal (HDMI, VGA, YPbPr or CV) inputs on
DVI-U connectors; and 2 HDBaseT inputs. It scales the video, embeds the audio,
and outputs the signal to two independent HDMI outputs –each with a parallel
HDBaseT output. The unit has both analog and embedded audio inputs and
outputs, and includes audio DSP features. Two microphone inputs are also
incorporated, as well as digital, analog balanced stereo and amplified speaker
outputs. The machine may be externally controlled via its built-in webpages,
RS-232 and IR; as well as via its front-panel and user-friendly menu-driven OSD.
The VP-778 Presentation Switcher / Scaler 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, transition type (swap or follow) and transition
effect (cut or fade) via the OSD menu
Dual scalers—for “live” seamless transitions from one source to another—
with two independent outputs: a channel 2 output and a channel 1 output.
The channel 2 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
8 CH2 input buttons for switching a selected input to the channel 2 output
and 8 CH1 input buttons for switching a selected input to the channel 1
output
Main and PiP window customization in the overlay mode
Front, back, ceiling front and ceiling back projection setups

VP-778 – Overview
5
Maximum output resolution –4K30 UHD (3840x2160), in the Single Window
mode, HDTV and computer graphics resolutions with selectable refresh rates
Selectable HDMI, VGA, YUV or CV on two DVI-U inputs, four HDMI and two
HDBT inputs
Two programmable user buttons that can launch a programmed command
(for example, to turn a projector on/off) to a selected destination (DATA
RS-232 port, HDBT IN1, HDBT IN2 HDBT OUT1, HDBT OUT2 or all) with a
press of a button
Serial matrix –Up to eight sets of unidirectional connections can be
configured for passing serial data from a selected source to a selected
destination (port tunnelling, the DATA RS-232 port, HDBT IN1, HDBT IN2
HDBT OUT1 or HDBT OUT2)
HDBaseT™ technology with a maximum data rate of up to 6.75Gbps
(2.25Gbps per graphic channel)
System range (HDBaseT) –Up to 130m (430ft) normal mode; up to 180m
(590ft) in ultra-mode (1080p @60Hz @24bpp) when using Kramer cables.
For optimum range and performance use the recommended Kramer
cables available at www.kramerav.com/product/VP-778.
Balanced stereo audio inputs, with two unbalanced microphone inputs, as
well as digital stereo and balanced stereo outputs
A built-in 2x10W power amplifier with speaker outputs on a 4-pin terminal
block connector
Selectable microphone talkover or mix modes
Auto switching, automatically scans the inputs (based on a predefined
priority) and selects the first live one found or the last connected
Audio-Follow-Video (AFV) and breakaway options
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

VP-778 – 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-778 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.
3.2 About HDBaseT™ Technology
HDBaseT™ is an advanced all-in-one connectivity technology (supported by the
HDBaseT Alliance). It is particularly suitable in the ProAV –and also the home –
environment as a digital networking alternative, where it enables you to replace
numerous cables and connectors by a single LAN cable used to transmit, for
example, uncompressed full high-definition video, audio, IR, as well as various
control signals.
The products described in this user manual are HDBaseT certified.
3.3 Using Twisted Pair Cable
Kramer engineers have developed special twisted pair cables to best match our
digital twisted pair products. For optimum range and performance use the
recommended Kramer cables available at www.kramerav.com/product/VP-778.
We strongly recommend that you use shielded twisted pair cable.
