Introduction
Welcome to Kramer Electronics! Since 1981, Kramer Electronics has been providing a world
of unique, creative, and affordable solutions to the vast range of problems that confront the
video, audio, presentation, and broadcasting professional on a daily basis. In recent years, we
have redesigned and upgraded most of our line, making the best even better!
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 www.kramerav.com/downloads/VP-439 to check for up-to-date user manuals,
application programs, and to check if firmware upgrades are available (where appropriate).
Achieving 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-439 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.

Overview
The VP−439 is a high−performance digital scaler for computer graphics video, composite and
HDMI signals, including audio. It up− or down−scales the selected HDMI, CV or computer
graphics video/YPbPr input and outputs it to HDMI.
The audio input source is selectable from Web pages–either from the relevant analog audio
input, or de-embedded from the HDMI input. The audio output can be delayed for lip-sync
compensation, and is available on the analog stereo output, as well as being embedded onto
the HDMI output.
More specifically, the VP-439 features:
•HDTV compatibility and scales to resolutions up to 1080p/WUXGA
•Clean and quiet auto-switching that searches for valid signal when the input signal is
lost with no video glitches or audible clicks or noises
•Automatic detection and selection of the audio source for the HDMI input. Default
selection is HDMI –if this is not present, then the machine uses the audio from the
analog input
•Auto-power down if no valid input signal is detected for a period of 2 to 3 minutes, the
HDMI output is shut down, and the PC output syncs are disabled
•HDCP enabling/disabling
•Analog audio inputs for the CV, PC and HDMI inputs
•Lip sync delay
•An On-Screen Display (OSD) for easy setup and adjustment, accessible via the front-
panel buttons
•An OSD INFO screen showing the selected input source, input and output resolutions,
HDCP status, firmware version, etc.
•A built-in ProcAmp for convenient adjustment of video parameters, such as brightness,
contrast, color, sharpness and hue
•A non-volatile memory that retains the last settings used
•Convenient setup and control options –front panel buttons, OSD, Web page

Connecting the VP-439
Always switch off the power to each device before connecting it to your VP-439. After
connecting your VP-439, connect its power and then switch on the power to each device.
To connect the VP-439 as illustrated in the example in Figure 3:
1. Connect an HDMI source (for example, from a Blu-ray player) to the HDMI IN HDMI
connector.
2. Connect a PC graphics and unbalanced stereo audio source (for example, from a laptop
PC) to the PC IN 15-pin HD and 3.5mm mini jack connectors.
3. Connect a composite video and unbalanced stereo audio source (for example, from a
DVD payer) to the CV IN RCA and LEFT/RIGHT RCA connectors.
4. Connect the HDMI OUTPUT on a DVI-I connector and the LEFT/RIGHT unbalanced
stereo audio on two RCA connectors to an HDMI acceptor (for example, to a display with
speakers).
5. If desired, connect the ETHERNET RJ-45 connector to a control device (for example, a
PC).
