VP-730 – Overview 3
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 audio 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 technology. The output signal is available simultaneously on
two 15-pin HD computer graphics video (PC) connectors and on an 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-picture, picture-and-picture, and split screen capability. Any 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 HDMI inputs and 1 USB
input (for reading JPEG picture files that are recognized up to 2048x1536 and
do not exceed 1MB)
•HDTV compatible component input
•HDTV output resolutions - 720p 1080i, and 1080p
•Scaled video outputs - HDMI and computer graphics video
•HDMI support of up to 2.25Gbps bandwidth per graphic channel
Suitable for resolutions up to UXGA at 60Hz, and for all HD resolutions
•Multiple computer graphics output resolutions - including a user-defined

output resolution with selectable refresh rates
•Multiple aspect ratio selections
•Companion AFV (audio-follow-video) for every analog video input
•Embedded audio on the two HDMI inputs and output
The embedded audio feature is not available for the RGB resolutions 1920x1200 and
1920x1080. (It is available for 1080p)
•Built-in noise reduction and picture enhancement features
•Audio inputs – selectable S/PDIF or balanced audio input for each of the two
universal video inputs, for each of the four PC video inputs on 5-pin terminal
blocks; and embedded audio on the two HDMI inputs
•Audio outputs - S/PDIF (RCA connector) and balanced stereo audio (5-pin
terminal block). Transcodes stereo or S/PDIF audio to both stereo and S/PDIF
audio and embeds audio onto the HDMI output
Tip: To use a 5.1 digital audio source, connect this HDMI or S/PDIF source (for
example, a Blu-ray player) directly to your receiver or display
•One stereo speaker output, 6W per channel into 8 Ω, on a 4-pin terminal block
connector
•Built-in Time Base Corrector - stabilizes video sources with unstable sync
•Built-in video Proc-Amp - color, hue, sharpness, contrast, and brightness are
set individually for each input
•A BLANK button, a FREEZE button, a RESET TO XGA/720P button (to
hardware-reset the output resolution); and a PANEL LOCK button
The front panel blank, freeze and lock buttons can be programmed via the OSD menu
(see Page 34)
•Built-in audio Proc-Amp with bass, treble, balance and loudness control, as
well as audio delay
•Firmware upgrade performed via the USB port
•Firmware upgrade for audio via the designated 3-pin RS-232 AUDIO PROG.
connector
•Slideshow option, letting you run a slideshow via the USB port
•An OSD (On-Screen Display) – for making adjustments – that can be located
anywhere on the screen

VP-730 – Overview 5
In addition, the VP-730:
•Includes non-volatile memory that retains the last settings, after switching the
power off and then on again
•Digitally reprocesses the signal to correct mastering errors and regenerates
the video at a higher line and pixel rate format, providing native-resolution
video for LCD, DLP and plasma displays
•Is specifically designed to improve video quality by reducing chroma noise
•Includes numerous filters and algorithms for eliminating picture artifacts
•Scales and zooms (to up to 400% of the original size)
•Can provide non-linear scaling for 4:3 and 16:9 transformation
Control your VP-730 directly via the front panel push buttons, or:
•By RS-232 serial commands transmitted by a touch screen system, PC, or
other serial controller
•Remotely, from the infrared remote control transmitter (with on-screen menus)
The VP-730 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.

This section provides instructions for rack mounting the unit.

10 VP-730 - Connecting the VP-730
5 Connecting the VP-730
Always switch off the power to each device before connecting it to your
VP-730. After connecting your VP-730, connect its power and then
switch on the power to each device.
To connect the VP-730 as illustrated in the example in Figure 3, do the following:
1. Connect the video sources:
A component video source (for example, a DVD player) to the
UNIV. IN 1 RCA connectors, Y/CV, Pb/C and Pr
Component video is sometimes called YUV, or Y, B-Y, R-Y
A composite source (for example, a DVD player) to the UNIV. IN 2
RCA connector
A computer graphics source to the PC 1 IN 15-pin HD computer
graphics video connector
An HDMI source (for example, a DVD player) to the HDMI 1 IN
connector
A graphics data source (for example, JPEG files that should be smaller
than 1MB and should not exceed a resolution of 2048x1536, from a
PC or a USB flash drive) to the USB connector on the front panel of
the machine
2. Connect the balanced stereo audio sources, that is, the audio of:
Component video source 1 to the AUDIO UNIV. IN 1 terminal block
Composite video source to the AUDIO UNIV. IN 2 terminal block
Computer graphics source to the AUDIO PC 1 terminal block
Although this connecting example shows only several inputs that are
connected, you can connect all the inputs simultaneously.

3. Connect the video outputs:
The HDMI OUT connector to an HDMI acceptor (for example, a
plasma display)
The PC OUT 1 15-pin HD computer graphics video connector to a video
acceptor (for example, an analog display 1)
In the HDTV mode, the signal goes out via three PINS: PIN 1 is Red or Pr, PIN 2
is Green or Y, PIN 3 is Blue or Pb
The PC OUT 2 15-pin HD computer graphics video connector to a
video acceptor (for example, an analog display 2)
In the HDTV mode, the signal goes out via three PINS: PIN 1 is Red or Pr, PIN 2
is Green or Y, PIN 3 is Blue or Pb
4. Connect the AUDIO OUT 5-pin terminal block and/or the S/PDIF digital audio
output to audio acceptors.
5. Connect the SPKR OUT block connector to a pair of loudspeakers, 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.
We recommend that you use only the power cord that is supplied with this machine
7. If required, connect a PC via RS-232, see Section 5.1
The USB connector, audio sources and acceptors, and power cord are
not shown in Figure 3.

5.1 Connecting a PC
You can connect to the unit via a crossed RS-232 connection, using for example, a
PC. A crossed cable or null-modem is required as shown in method A and B
respectively. If a shielded cable is used, connect the shield to pin 5.
Method A (Figure 4)—Connect the RS-232 9-pin D-sub port on the unit via a
crossed cable (only pin 2to pin 3, pin 3to pin 2, and pin 5to pin 5need be
connected) to the RS-232 9-pin D-sub port on the PC.
Note:There is no need to connect any other pins.
Figure 4: Crossed Cable RS-232 Connection
Hardware flow control is not required for this unit. In the rare case where a
controller requires hardware flow control, short pin 1 to 7 and 8, and pin 4 to 6 on
the controller side.
Method B (Figure 5)—Connect the RS-232 9-pin D-sub port on the unit via a
straight (flat) cable to the null-modem adapter, and connect the null-modem adapter
to the RS-232 9-pin D-sub port on the PC. The straight cable usually contains all
nine wires for a full connection of the D-sub connector. Because the null-modem
adapter (which already includes the flow control jumpering described in Method A
above) only requires pins 2, 3 and 5 to be connected, you are free to decide
whether to connect only these 3 pins or all 9 pins.
