VP-440 –Introduction

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-440 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-440 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.

Safety Instructions

Caution: There are no operator serviceable parts inside the unit.

Warning: Use only the power cord that is supplied with the unit.

Warning: Disconnect the power and unplug the unit from the wall before installing.

and so on.

•Built-in ProcAmp –color, hue, sharpness, noise, contrast and brightness.

•Supports 4:4:4 (RGB and YUV) as well as 4:2:2 (YUV) color sampling in Native mode.

•Maintains constant output sync –there is no disruption on the output while switching

between inputs and when no video is detected.

•Dedicated RS-232 port for bidirectional data tunneling via HDBT.

•Front panel lockout.

•Non-volatile memory –saves final settings.

Kramer Electronics Ltd.

VP-440 –Connecting the VP-440

Connecting the VP-440

Always switch off the power to each device before connecting it to your VP-440. After

connecting your VP-440, 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.

Figure 3: Connecting the VP-440 Presentation Switcher / Scaler

To connect the VP-440, as illustrated in the example in Figure 3, do the following:

1. Connect an HDMI source (for example, a Blu-ray disk player) to the HDMI 1 (H1) 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-440 via a DVI-HDMI adapter. When using this adapter, you

can connect the audio signal via the 3.5mm mini jack connector .

2. Connect a computer graphics source to the PC 1 15-pin HD VIDEO INPUT

connector (from 1 to 2).
