Introduction
Welcometo KramerElectronics! Since1981, KramerElectronics has been providing a world
of unique, creative,and affordablesolutions to the vast range of problems that confrontthe
video, audio, presentation, and broadcasting professional on a daily basis. In recent years,
we have redesigned and upgraded most of our line, makingthe best even better!
Getting Started
We recommendthat you:
•Unpack the equipment carefully and save the original box and packaging materials for
possible future shipment.
•Reviewthe contents of this user manual.
Go to www.kramerav.com/downloads/VP-551X tocheck forup-to-date user manuals,
application programs, and to check if firmwareupgrades are available (where appropriate).
Achieving the Best Performance
•Use only good quality connection cables (we recommendKramerhigh-performance,
high-resolution cables) to avoid interference, deterioration in signal quality due to poor
matching, and elevated noise levels (oftenassociated with low quality cables).
•Do not secure the cables in tight bundles or roll the slack into tight coils.
•Avoid interferencefrom neighboring electrical appliances that may adversely influence
signal quality.
•Position your Kramer VP-551X away from moisture, excessivesunlight and dust.
Safety Instructions
Caution:
•This equipment is to be used only inside a building. It may only be connected to other
equipment that is installed inside a building.
•For products with relay terminals and GPI\O ports, please referto the permitted rating
foran external connection, located next to the terminal or in the User Manual.
•There are no operator serviceable parts inside the unit.
Warning:
•Use only the power cordthat is supplied with the unit.
•Disconnect the power and unplug the unit from the wall before installing.
•Do not open the unit. High voltages can cause electrical shock! Servicingby qualified
personnel only.
•To ensure continuous risk protection, replace fuses only according to the rating
specified on the product label which located on the bottom of the unit.

Overview
Congratulations on purchasing your Kramer VP-551X 4K Presentation MatrixSwitcher
Scaler.
VP-551X is a versatile, professional presentation scaler/switcher for4K@60 (4:4:4) HDMI™,
and forVGAand composite video signals. The unit scales the video and provides options to
use the embedded HDMIaudio or to select the companionaudio channel from one of ten
analog audio input signals. Afterprocessing and scaling, the embedded AV signal is sent to
the HDMIand the HDBaseT outputs simultaneously, and the audio is also sent to a balanced
stereo audio output, S/PDIFdigital output and a pair of loudspeakers.
VP-551X provides exceptional quality, advanced and user-friendly operation, and flexible
control.
Exceptional Quality
•High-Resolution Video –Supports and scales to/from resolutions up to 4K@60Hz
(4:4:4) on the HDMIinputs and output, and 4K@60Hz (4:2:0) on the HDBaseToutput.
•Complies with HDMI,HDCP 2.2 and HDR10standards.
•HDMISupport –HDR10, CEC,xvYCC color(on input), Dolby TrueHD/DTS-HD Master
Audio (by-pass), as specified in HDMI2.0 as specified in HDMI2.0.
•Professional Video Quality –Provides selectable aspect ratios (full, best fit,over scan,
under scan, letter box and pan scan). Includes built-in ProcAmpforcolor, hue,
sharpness, noise, contrast and brightness control. Supports 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-scaling and down-scaling of
all video input signals.
•High-PerformanceSwitcher/Scaler –Scales HDMI,VGAand Composite video signals
foroutput to two mirrored outputs: HDMIand HDBaseT. Constant output sync prevents
signal disruption when switching between inputs and when no video is detected.
•PowerfulAudio Features –Including DSP with audio equalization, mixing,delay and
more.
•HDTVCompatible.

Advanced and User-friendly Operation
•4K and Legacy Inputs –8 4K@60 (4:4:4) HDMIinputs, 1 VGAinput, and 1 CV
(composite video) input.
•Versatile Powering Options –Powered by universal power supply (100-240V AC)and
provides PoEpower to a compatible HDBaseT device.
•Non-Volatile Memory –Savesfinal settings before shutdown and retains them fornext
power up.
•Convenient Control Options –Local control via frontpanel buttons, RS-232, IR remote,
and OSD.Long-distance control via embedded webpages and Ethernet.
•Easy Installation –19” enclosure for rack mounting a unit in a 1U rack space with
included rack ears and universal 100-240V AC power connection.
•Auto-switching and auto-scanning of inputs.
•AdvancedEDID management per input.
Flexible Connectivity
•Versatile Audio Options –Includes a companionanalog audio input foreach of the 10
video inputs, enabling the user to embed a separate analog audio channel into each
video signal or to bypass an embedded audio input (forexample, to support
multi-channel, compressed audio formatslike Dolby and DTS).
•Provides 2 independent microphone inputs on 6.3mm connectors(each with optional
48V phantom power) formixing, switching or talk–over.
•On the output, besides the audio embedded on HDMIand HDBaseT outputs, the audio
signal is also extracted (de-embedded) and output as balanced stereo analog audio,
and as digital audio through an S/PDIFconnected device, as well as amplified to 20W
per channel forconnection to loudspeakers.
•Video Inputs –8 HDMI,1 PC and 1 CV.
•Video Outputs –1 HDBaseTand 1 HDMI.
Typical Applications
VP-551X is ideal forthe following typical applications:
•Projection systems in conferencerooms,boardrooms, hotels and churches.
•Hometheater up-scaling.
Controlling your VP-551X
Control your VP-551X directly via the frontpanel push buttons (with on-screen menus, or:
•By RS-232 serial commandstransmitted by a touch screen system,PC, or other serial
controller.
•Remotely,from the infrared remote control transmitter.
•Via the Ethernet using built-in user-friendly webpages.
