3 Overview

The Kramer VP-730 is a 9-input Proscale™ Presentation Switcher / Scaler.
Each audio input can accept balanced stereo audio or digital S/PDIF audio.
The VP-730 has a balanced stereo audio output and a digital S/PDIF a udio
output.

The VP-730 scales any composite, s-Video (Y/C), component video (YPbPr),
HDMI or computer graphics video signal, as well as jpeg files (via USB) up
or down to a selectable graphics or HDTV output resolution and provides
glitch-free switching between sources through FTB™ (fade-thru-black)
switching technolog y. The out put signal is avail able simultaneously on two
15-pin HD computer graphics video (PC) connectors and on a n HDMI
connector.

The VP-730 features include:

• Silicon Optix HQV® Video Processing - HQV (Hollywood Quality Video)

processing represents the state-of-the-art in video processing technology, with
the highest quality de-interlacing, noise reduction, and scaling performance for
both standard-definition and high-definition signals

• Fade-Thru-Black (FTB™) Switching - the video fades to black and then the

new input fades from black for glitch-free and smooth switching. The output
signal provides constant sync so the display never glitches

• K-IIT XL™ Picture-in-Picture Image Insertion Technology - ultra stable

picture-in-pictur e, picture-and-picture, and split screen capability. A video
source can be inserted into or positioned next to a computer graphics video
source or vice versa with window positioning and sizing controls

• Two user definable (universal) video inputs (each can be set as composite video,

s-Video (Y/C) or component video), four computer graphics video inputs (each
can be set as RGBHV or YPbPr), two HDM I inputs and 1 USB input (for
reading JPEG picture files

1

• HDTV compatible component in put

)

• HDTV ou tpu t res olu ti ons - 480p, 576p, 720p, 1080i, and 1080p

• Scaled video outputs - HD MI and computer graphics video

• HDMI supports up to 2.25Gbps ba n dwidth per graphi c ch annel

2

• Multi ple com pute r gr aph ics outpu t re solu ti ons - including a user-defined output

resoluti on wi th sele ctable refresh rates

• Multiple aspect ratio selections

• Companion AFV (audio-follow-video) for every analog video input - supports

3.2 Recommendations for Best Perfor m ance

To achieve the best performance:

• Connect only good quality connection cables, thus avoiding interference,

deterioration in signal quality due to poor matching, and elevated noise-levels
(often asso ciated with low quality c ables)

• Avoid interference from neighboring electrical appliances and position your

Kramer VP-730 aw ay from moisture, excessive sunlight and dust

5 Installing in a Rack

This section descr ibes what to do befor e installing in a rack and how to rack
mount.

Before Installing in a Rack

How to Rack Mount

Before installing in a rack, be sure that the environment is
within the recommended range:

To rack-mount a machine:

1. Attach both ear brackets to the
machine. To do so, remove the
screws from each side of the
machine (3 on each side), and
replace those screws through the
ear brackets.

2. Place the ears of the machine
against the rack rails, and insert the
proper screws (not provided)
through each of the four holes in the
rack ears.

Note that:

• In some models, the front panel

may feature built-in rack ears

• Detachable rack ears can be
removed for desktop use

• Always mount the machine in the
rack before you attach any cables
or connect the machine to the
power

• If you are using a Kr am er rack
adapter kit (for a machine that is not
19"), see the Rack Adapters user
manual for installation instructions
(you can download it at:
http://www.kramerelectronics.com)

Operating temperature range

+5° to +45° C (41° to 113° F)

Operating humidity range 10 to 90% RHL, non-condensing
Storage temperature range

-20° to +70° C (-4° to 158° F)

Storage humidity range 5 to 95% RHL, non-condensing

!

CAUTION

!!

When installing on a 19" rack, avoid hazards by taking
care that:

1. It is located within the recommended environmental
conditions, as the op era ti ng ambi ent t e mperature of a
closed or multi unit rack assembly may exceed the
room ambient temperature.

2. Once rack mounted, enough air will still flow around
the machine.

3. The machine is placed straight in the correct
horizontal positi on.

4. You do not overlo ad the circuit(s). When connecting
the machine to the supply circuit, overloading the
circuits might have a detrimental effect on overcurrent
protection and supply wiring. Refer to t he app ro priate
nameplate ratings for information. For example, for
fuse replacement, see the value printed on the
product label.

5. The machine is earthed (grounded) in a reliable way
and is connected onl y to an ele ctric ity socket with
grounding. Pay particular attention to situations where
electricity is supplied indirectly (when the power cord
is not plugged directly into the socket in the wall), for
example, when using an extension cable or a power
strip, and that you use only the power cord that is
supplied with the machine.

audio output to audio acceptors.

5. Connect the SPKR OUT block connec t or to a pair of lou dspeak ers, by
connecting the left loudspeaker to the “L+” and the “L-” terminal block
connectors, and the right loudspeaker to the “R+” and the “R-” terminal
block connectors. Do not Ground the loudspeakers.

6. Connect the power cord

5,8

7. If required, connect a PC via RS-232, see section . 6.1.

1 Although this example shows only several inputs that are connected, you can connect all the inputs simultaneously
2 Switch OFF the power on each device before connecting it to your VP-730. After connecting your VP-730, switch on its
power and then switch on the power on each device
3 You do not have to connect all the inputs
4 Sometimes called YUV, or Y, B-Y, R-Y, or Y, Pb, Pr
5 Not illustrated in

6.1 Connecting a PC

You can connect a PC (or other controller) to the VP-730 via the RS-232 port
for remote control.

To connect a PC to a VP-730 unit, using the N ull-modem adapter provided
with the machine (recommended):

• Connect the RS-232 9-pin D-sub rear panel port on the VP-730 unit to th e

Null-modem adapter and connect the Null-modem adapt er with a 9-w ire f lat
cable to the RS-232 9-pin D-sub port on your PC

To connect a PC to a VP-730 unit, without us ing a Null-modem adapter:

• Connect the RS-232 9-pin D-sub port on your PC to the RS-232 9-pin D-sub

rear panel port on the VP-730 unit, forming a cross-connection
