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!

Congratulations on purchasing your Kramer VP-444 Presentation Switcher/Scaler. This product, which incorporates HDMI™ technology, is ideal for:

• Projection systems in conference rooms, boardrooms, hotels and churches

• Home theater up-scaling

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-444 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-444 away from moisture, excessive sunlight and dust.

Safety Instructions

Caution:

• This equipment is to be used only inside a building. It may only be connected to other equipment that is installed inside a building.

• For products with relay terminals and GPI\O ports, please refer to the permitted rating for an external connection, located next to the terminal or in the User Manual.

• There are no operator serviceable parts inside the unit.

Overview

The VP-444 is a high−performance presentation scaler/switcher for HDMI and computer graphics signals. The unit scales the video, embeds the audio, and outputs the signal to two HDMI (with embedded audio) outputs (with S/PDIF and balanced stereo audio) simultaneously.

The VP-444 features:

• PixPerfect™ scaling technology – Kramer’s precision pixel mapping and high quality scaling technology. High-quality 3:2 and 2:2 pull down de-interlacing and full up and down scaling of all video input signals.

• HDTV compatibility.

• HDCP compliance - The HDCP (High Definition Content Protection) license agreement

allows copy−protected data on the HDMI input to pass only to the HDMI outputs.

• 12 video inputs - 10 HDMI on HDMI connectors, 2 computer graphics video on 15−pin HD connectors.

• Two HDMI scaled outputs.

• Up to UXGA/1080p output resolutions.

• Two microphone inputs that can be used by mixing, switching or talk-over.

• Companion AFV (Audio-Follow-Video) - stereo audio for every input (on terminal blocks).

• 12 unbalanced stereo inputs on terminal blocks as well as embedded audio for the HDMI

inputs, each with individual level controls.

• Audio outputs – one S/PDIF on an RCA connector, one balanced stereo audio on a terminal block as well as embedded audio on the HDMI outputs.

• Multiple aspect ratio selections - full, best fit, over scan, under scan, letter box and pan

VP-444 – Introduction

scan.

• Selectable panel lock modes.

• Powerful audio features via DSP technology including audio equalization, mixing, delay

and so on.

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

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

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

between inputs and when no video is detected.

• Front panel control - audio mute and freeze frame.

• Front panel lockout.

• Non-volatile memory - saves final settings.

Control your VP-444:

• 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 with OSD (on-screen display).

• Via the Ethernet with built-in Web pages.

The VP-444 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.

For optimum range and performance use the recommended Kramer shielded twisted pair cables available at www.kramerav.com/product/VP-444.

Typical Applications

VP-444 is ideal for the following typical applications:

• Projection systems in conference rooms, boardrooms, classrooms, hotels and churches

• Home theater up–scaling

Mounting VP-444

This section provides instructions for mounting VP-444. Before installing, verify that the environment is within the recommended range:

• Operation temperature – 0 to 40C (32 to 104F).

• Storage temperature – -40 to +70C (-40 to +158F).

• Humidity – 10% to 90%, RHL non-condensing.

• VP-444 must be placed upright in the correct horizontal position.

Caution:

• Mount VP-444 before connecting any cables or power.

Warning:

• Ensure that the environment (e.g., maximum ambient temperature & air flow) is compatible for the device.

• Avoid uneven mechanical loading.

• Appropriate consideration of equipment nameplate ratings should be used for avoiding

overloading of the circuits.

• Reliable earthing of rack-mounted equipment should be maintained.

To mount the VP-444 on a rack

MIC SELECT – select MIC1, MIC2 or BOTH When in TALKOVER mode, set the: DEPTH [%] – to determine the decrease of the audio level during microphone 1 takeover (press + to further decrease the talkover audio output level; press – to lessen the talkover output audio decrease level) TRIGGER – to determine the microphone threshold level that triggers the audio output-level decrease. ATTACK TIME – to set the transition time of the audio level reduction after the signal rises above the threshold level HOLD TIME – to define the time period talkover remains active although the signal falls below the threshold level (for a short period of time) RELEASE TIME – to define the transition time for the audio level to return from its reduced level to its normal level after the Hold Time period MIC GAIN BOOST – set to ON or OFF. Some versions of the VP-444 include this selection. In the case that the setting selected is not supported by the hardware of the unit, the mic may be disabled

MIC VOLUME

Set the microphone volume for MIC1 and MIC2

NOISE MUTE

Set to ON or OFF. ON: Unit enables the audio output only after validating that there is audio present on the input. (Note that the unit takes 1 – 2 seconds to detect the presence of audio, so there is a delay before the audio is heard after switching to a new input). OFF: The unit does not check the validity of the audio. Audio is always enabled and there is no delay before the audio is heard after switching inputs.

Operating via Ethernet

You can connect to the VP-444 via Ethernet using either of the following methods:

• Directly to the PC using a crossover cable (see Connecting the Ethernet Port Directly to

a PC on page 14)

• Via a network hub, switch, or router, using a straight-through cable (see Connecting the

Ethernet Port via a Network Hub or Switch on page 16)

If you want to connect via a router and your IT system is based on IPv6, speak to your IT department for specific installation instructions.

Connecting the Ethernet Port Directly to a PC

You can connect the Ethernet port of the VP-444 directly to the Ethernet port on your PC using a crossover cable with RJ-45 connectors.

This type of connection is recommended for identifying the VP-444 with the factory configured default IP address.

After connecting the VP-444 to the Ethernet port, configure your PC as follows:

1. Click Start > Control Panel > Network and Sharing Center.

2. Click Change Adapter Settings.

3. Highlight the network adapter you want to use to connect to the device and click Change settings of this connection. The Local Area Connection Properties window for the selected network adapter appears as shown in Figure 8.
