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
