i
!
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
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-441 away from moisture, excessive sunlight and dust

VP-441 - Overview
3 Overview
The Kramer VP-441 is a high quality presentation switcher and scaler. It accepts
one of seven inputs: a component video on RCA connectors, computer graphics on
a 15-pin HD connector, composite video on an RCA connector, s-Video on a
4-pin connector and two HDMI signals. 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-441 is HDTV compatible and the resolution can be up- or down-scaled as
follows: Native, VGA, SVGA, XGA, SXGA, UXGA, 480i, 480p, 576i, 576p,
720p (@50 and 60Hz), 1080i (@50 and 60Hz), 1080p (@50 and 60Hz), WXGA,
WSXGA, WUXGA, 1280x800, 1440x900, 1400x1050, 1600x900 and 2K resolutions
(2048x1080@50Hz and 2048x1080@60Hz).
The VP-441 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-441 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
Has an HDTV compatible component input
Page 9
VP-441 – Overview
5
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
Has a non-volatile memory that retains the last settings used
Supports firmware upgrade via RS-232
Control your VP-441:
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-441 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.

Always switch off the power to each device before connecting it to
your VP-441. After connecting your VP-441, 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.

5 Connecting the VP-441
To connect the VP-441, 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 VIDEO
INPUT connector.
Alternatively, you can connect the DVI connector on the DVD player to the HDMI
connector on the VP-441 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 VGA 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.
4. Connect an s-Video source (for example, an s-Video player) to the YC 4-pin
VIDEO INPUT connector.
5. Connect a component video source (for example, a component video player)
to the COMP 1 PR, PB and Y, VIDEO INPUT RCA connectors.
6. Connect the audio input signals to the AUDIO IN terminal block connectors,
as required (not shown in Figure 3).
7. Connect the RGBHV VIDEO OUTPUT BNC connectors to an RGBHV
acceptor (for example, an RGBHV display).
8. Connect the HDMI VIDEO OUTPUT connector to an HDMI acceptor (for
example, a plasma display).
Page 14

VP-441 - Connecting the VP-441
9. Connect the VGA VIDEO OUTPUT 15-pin HD connector to a VGA acceptor
(for example, a projector).
10. Connect the audio output signals to the OUT stereo analog audio acceptor
and/or the digital audio acceptor, as required (not shown in Figure 3).
11. Connect the power cord (not shown in Figure 3).
12. If required, connect:
