VP-440 - 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 http://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).
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-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.

VP-440 - Overview
3 Overview
The VP-440 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 both an HDMI and an HDBaseT output, as well as outputting to
unbalanced stereo audio.
The VP-440 features:
PixPerfect™scaling technology –Kramer’s precision pixel mapping and high
quality scaling technology, with full up and down scaling of all video input
signals
HDTV compatibility
HDCP compliance
6 video inputs - 4 HDMI on HDMI connectors, 2 computer graphics video on
15−pin HD connectors
Scaled output on HDMI and HDBT connectors simultaneously
System Range for the HDBT inputs and outputs - Up to 70m (230ft)
For optimum range and performance using HDBaseT™, use Kramer's
BC−HDKat6a cable. Note that the transmission range depends on the
signal resolution, source and display used. The distance using
non−Kramer CAT 6 cable may not reach these ranges.
Up to UXGA/1080p output resolutions
Microphone input with audio DSP options including mixing and talk-over
Companion AFV (Audio-Follow-Video) –stereo audio for every video input
6 unbalanced stereo inputs on 3.5mm connectors as well as embedded audio
for the HDMI inputs, each with individual level controls
Audio outputs –one unbalanced stereo on a 3.5mm connector as well as
embedded audio on the HDMI and HDBT outputs
Multiple aspect ratio selections - full, best fit, over scan, under scan, letter box
and pan scan

VP-440 - Overview

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 4:2:2 (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
Control your VP-440:
Directly, via the front panel push buttons
By RS-232 serial commands transmitted by a touch screen system, PC, or
other serial controller
Via the OSD (on-screen display)
Via remote contact-closure switches
Via the Ethernet with built-in Web pages
The VP-440 is housed in a 1/2 19" 1U enclosure, letting 2 units to be rack mounted
side-by-side in a 1U rack space with the optional RK-1 universal rack adapter.
3.1 Using Twisted Pair Cable for HDBT
Kramer engineers have developed special twisted pair cables to best match our
digital twisted pair products; BC−HDKat6a (CAT 6 23 AWG cable) significantly
outperforms regular CAT 5 / CAT 6 cables.
We strongly recommend that you use shielded twisted pair cable.

4 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.
To connect the VP-440, as illustrated in the example in Figure 3, do the following:
1. Connect an HDMI source (for example, a BluRay 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 terminal block connector
2. Connect a computer graphics source to the PC 1 15-pin HD VIDEO INPUT
connector (from 1 to 2).
3. Connect the audio input signals to the AUDIO INPUT 3.5mm mini jack
connectors, as required (not shown in Figure 3).
4. Connect the HDMI OUT connector to an HDMI acceptor (for example, an
LCD display).
5. Connect the HDBT OUT connector to an HDBT receiver (for example, the
output of TP-580R connected to HDBT).
6. Connect the AUDIO OUT 3.5mm mini jack connector to an unbalanced stereo
audio acceptor (not shown in Figure 3).
7. On the front panel, connect a microphone to the MIC 6.5mm phone jack and
set it to condenser or dynamic type.
8. Connect the power cord (not shown in Figure 3).

RS-232 DATA 3-pin terminal block connector (Tx, Rx, G) to a PC for
sending RS-232 commands via HDBT
RS-232 CONTROL 3-pin terminal block connector (Tx, Rx, G) to a PC to
control the unit
10. Connect the INPUT SELECT 7-pin terminal block contact-closure remote-

MIC SETTINGS
MIC MODE - set the mode to OFF, MIXER, TALKOVER or MIC ONLY.
When in TALKOVER mode (see Figure 7), 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 [dB] –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 VOLUME
Set the microphone volume for MIC
DRC
Dynamic Range Compression –allows a dynamic volume range. Set to ON
to dynamically create a sound range according to the volume level. For
example, in a movie the volume will be high enough to hear the dialogues
and at the same time loud explosions and sudden noises in the soundtrack
will be toned down so others would not be disturbed.
ADVANCED
HDCP ON
INPUT
Select the HDCP option for the HDMI inputs (1 to 4): either ON (the
default) or OFF.
Setting HDCP support to disabled (OFF) on the HDMI input allows the
source to transmit a non-HDCP signal if required (for example, when
working with a Mac computer)
HDCP ON
OUTPUT
Set HDMI OUT and HDBT OUT:
Select FOLLOW INPUT or FOLLOW OUTPUT to define whether the
HDCP will follow the input or the output
When FOLLOW INPUT is selected, it changes its HDCP output setting (for
the HDMI output) according to the HDCP of the input. This option is
recommended when the HDMI/HDCP output is connected to a
splitter/switcher
When FOLLOW OUTPUT is selected, the scaler matches its HDCP output
to the HDCP setting of the HDMI/HDCP acceptor to which it is connected
AUTO SYNC
OFF
Turn to OFF (disable the AUTO SYNC OFF feature), FAST (for almost
immediate shut down if no input is present –about 10 seconds) or SLOW
(for shutdown after about 2 minutes).
This is useful, for example, when the output is connected to a projector,
and the projector will automatically shut down when it has no input
