VP-774 - 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/support/product_downloads.asp
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-774 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

VP-774 - Overview
3 Overview
The Kramer VP-774 is a high quality presentation switcher and scaler. It accepts
one of nine inputs: an SDI signal on a BNC connector, a DisplayPort (DP) signal on
a DisplayPort connector, one composite video signal on an RCA connector, two
computer graphics signals on 15-pin HD connectors, and four HDMI signals on
HDMI connectors. It scales the video, embeds the audio, and simultaneously outputs
the signal as follows: to two HDMI outputs, to an SDI output and to an HDBaseT TP
output, together with a digital audio output and a balanced stereo audio output.
The VP-774 Presentation Switcher / Scaler features:
PixPerfect™Scaling Technology –Kramer’s precision pixel mapping and
high quality scaling technology. High-quality 3:2 and 2:2 pull down de-
interlacing and full up and down scaling of all 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
An emergency alert system that can have a national or campus-wide
notification immediately displayed when an emergency situation develops, by
means of automatic text overlaying, either via a crawler or a full screen cover
up, as well as an optional audio alert
Port tunneling, bidirectional RS-232 interface –simple control commands
and data can flow in both directions from a controller to the VP-774 via the
Ethernet, allowing status requests and control of the destination unit
Advanced deinterlacing functions - including 3D comb filtering, film mode,
diagonal correction and motion detection

Scaled Outputs –2 HDMI outputs, an SDI output and an HDBaseT TP
output simultaneously
HDBaseT™ technology with a bandwidth of up to 6.75Gbps (2.25Gbps per
graphic channel)
Up to 130m (430ft) normal mode; up to 180m (590ft) Ultra mode (1080p
@60Hz @24bpp) when using BC-DGKat623 cables
For optimum range and performance, use Kramer's BC−DGKat524,
BC−DGKat623 and BC−DGKat7a23 shielded twisted pair (STP) cables.
Note that the transmission range depends on the signal resolution,
graphics card and display used. The distance using non−Kramer CAT 5,
CAT 6, and CAT 7 cables may not reach these ranges.
Output Resolutions –HDTV and Computer Graphics up to 2K and
1080p/UXGA with selectable refresh rates
Multiple Aspect Ratio Selections –Follow input, follow output, best fit,
letterbox
Multi-Standard SDI support - SDI (SMPTE 259M), HD-SDI (SMPTE 292M)
and 3G HD-SDI (SMPTE 424M)
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
Balanced stereo audio inputs, with two microphone inputs as well as digital
stereo and balanced stereo outputs
Selectable Microphone talkover or mix modes
Automatic detection and selection of the HDMI and DP embedded audio.
The VP-774 automatically outputs the signal from the HDMI and DP
embedded audio inputs or performs an analog takeover to output the
respective analog audio input
