VP-443 - 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-443 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-443 - Overview
3 Overview
The Kramer VP-443 is a high quality presentation switcher and scaler. It accepts
one of 10 inputs: four HDMI signals, two computer graphics signals on 15-pin HD
connectors, two composite video signals on RCA connectors and two component
video signals on RCA connectors. It scales the video, embeds the audio, and
outputs the signal as follows: to the HDMI output, to the computer graphics output,
and to the RGBHV video output together with a digital audio output and an analog
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-443 is HDTV compatible and the resolution can be up- or down-scaled as
follows: VGA, SVGA, XGA, SXGA, UXGA, 480i, 480p, 720p60, 1080i60, 1080p60,
576i, 576p, 720p50, 1080i50, 1080p50, WXGA, WSXGA, WUXGA, 1280x800,
WXGA+, SXGA+, 1600x900, 2K resolutions (2048x1080@50Hz and
2048x1080@60Hz), 480i59, 480p59, 720p59, 1080i59 and 1080p59.
The VP-443 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
Has analog audio inputs and digital (S/PDIF) and analog stereo audio
outputs as well as 5.1 analog audio bypass
The VP-443 converts digital audio information to Dolby 5.1 analog outputs, facilitating
the routing of up to six analog audio inputs (left, center, right, left surround, right
surround and subwoofer) directly to the output without being processed
Automatically detects and selects the audio source for the HDMI input.
Default selection is HDMI –if this is not present, the machine uses the audio
from the analog input
Comes with an On-Screen Display (OSD) for easy setup and adjustment,
accessible via the IR remote control and via the front-panel buttons
Is 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

VP-443 – Overview
5
Has a non-volatile memory that retains the last settings used
Supports firmware upgrade via RS-232
Control your VP-443:
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 the Ethernet
The VP-443 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.

5 Connecting the VP-443
Always switch off the power to each device before connecting it to
your VP-443. After connecting your VP-443, 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-443, as illustrated in the example in Figure 3, do the following:
1. Connect an HDMI source (for example, a DVD player) to the HDMI VIDEO
INPUT connector (from 1 to 4).
Alternatively, you can connect the DVI connector on the DVD player to the HDMI
connector on the VP-443 via a DVI-HDMI adapter. When using this adapter, you can
connect the audio signal via the terminal block connector
2. Connect a computer graphics source to the PC 1 15-pin HD VIDEO INPUT
connector.
3. Connect a composite video source (for example, a composite video player)
to the CV VIDEO INPUT RCA connector (from 1 to 2).
4. Connect a component video source (for example, a component video player)
to the COMP 1 PR, PBand Y, VIDEO INPUT RCA connectors.
5. Connect the audio input signals to the AUDIO IN terminal block connectors,
as required (not shown in Figure 3).
6. Connect the RGBHV VIDEO OUTPUT BNC connectors to an RGBHV
acceptor (for example, an RGBHV display).
7. Connect the HDMI VIDEO OUTPUT connector to an HDMI acceptor (for
example, a plasma display).
8. Connect the VGA VIDEO OUTPUT 15-pin HD connector to a VGA acceptor
(for example, a projector).
