VP-445 - Getting Started
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
Go to www.kramerav.com/downloads/VP-445 to check for up-to-date user
manuals, application programs, and to check if firmware upgrades are
available (where appropriate).
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 neighbouring electrical appliances that may adversely
influence signal quality.
Position your Kramer VP-445 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.

VP-445 - Overview
3 Overview
The VP-445 is a high-performance presentation scaler/switcher for HDMI, computer
graphics and composite video 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-445 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 –6 HDMI on HDMI connectors, 4 computer graphics video on
15−pin HD connectors and 2 composite video on RCA connectors.
Two HDMI scaled outputs (mirrored)
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 scan.
Powerful audio features via DSP technology including audio equalization,
mixing, delay and so on.
Built-in ProcAmp –color, hue, sharpness, noise, contrast and brightness.

VP-445 –Overview

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.
External device control via RS-232 port
Front panel control –audio mute and freeze frame.
Front panel lockout.
Non-volatile memory –saves final settings.
Control your VP-445:
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.
Via ETH using TCP.
The VP-445 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.

5 Connecting the VP-445
Always switch off the power to each device before connecting it to
your VP-445. After connecting your VP-445, 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.
To connect the VP-445, as illustrated in the example in Figure 3, do the following:
1. Connect an HDMI source (for example, a Blu-ray player) to the HDMI VIDEO
INPUT connector (from 1 to 6).
Alternatively, you can connect the DVI connector on the DVD player to the
HDMI connector on the VP-445 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 PC 1 15-pin HD VIDEO INPUT
connector (from 1 to 4).
3. Connect a composite video source to the CV 1 RCA connector (from 1 to2).
4. Connect the audio input signals to the AUDIO IN terminal block connectors,
as required (not shown in Figure 3).
5. If required, connect a microphone to the MIC 1 6mm jack (from 1 to 2) and
set the phantom power (48V) on or off.
6. Connect the HDMI OUT 1 connector to an HDMI acceptor (for example, an
LCD display), from 1 to 2.
7. 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).
8. Connect the power cord (not shown in Figure 3).
