3 Overview

The VP-725DSA Presentation Switcher / Scaler is designed for a wide
variety of presentation and multimedia applications. It is a true multi-standard
video to graphics scaler and presentation switcher for a wide variety of
presentation and multimedia applications. It consists of a very high quality
scaler with many user-selectable pixel-rates including VGA (640x480), SVGA
(800x600), XGA (1024x768), SXGA (1280x1024) and UXGA (1600x1200);
high definition television HDTV (480p, 720p and 1080i); and several optimum
plasma and LCD rates such as 852x1024i, 1024x1024i, 1366x768, 1365x1024,
1280x720, 720x483, 852x480, 1400x1050, 576P, 720x400, 832x624,
1024x800, 1152x864, 1152x870, 1152x900, 1280x960, 1280x768, 1024x576,
as well as a user definable output mode1.

In particular, the VP-725DSA:

 Offers high quality de-interlacing 3:2/2:2 pull down2

 Supports firmware upgrade via RS-232
 Includes non-volatile memory that retains the last setting, after switching

the power off and then on again

 Scales and zooms (to up to 400% of the original size)

 Digitally reprocesses the signal to correct mastering errors, and

regenerates the video at a chosen line and pixel rate format, providing, for
example, native-resolution video for LCD, DLP and Plasma displays

 Facilitates scaling of graphics resolutions to other resolutions

 Incorporates a unique graphics-scaling engine with image enhancement

algorithms, which are built into the firmware

 Is specifically designed to improve video quality by reducing chroma noise

 Includes an OSD (on-screen display) for making the adjustments that can

be located anywhere on the screen, and can be doubled in size. The OSD
can be used to deactivate the source prompt, choose the color of the blank
screen, and choose from three seamless switching transition speeds

 Consists of 5 video groups—composite video, s-Video, component video

(RGB or YPbPr), DVI-D and VGA—and each group has 4 inputs (except
for DVI which has 2 inputs). Each video input has its own corresponding
balanced stereo audio input on a terminal block connector

1 Recommended for advanced users only – non-standard settings may not be recognized by the display device

2 Accommodates the frame-rate of a converted movie (24 frames per second) to video frequencies (25 frames per second

(PAL); 30 frames per second (NTSC)

KRAMER: SIMPLE CREATIVE TECHNOLOGY

Overview

4

 Has multi-standard video support; supports VESA standards; HDTV

standards and other popular resolutions on the input. Does not support1
HDCP (High bandwidth Digital Content Protection) on the DVI2

 Features a Video Group Mode3 and a Scaler Mode4. These modes function

simultaneously and independently (except for DVI: once a DVI input is
selected in the Scaler Mode, that DVI input selection cannot be changed
in the Video Group Mode)

 Features an Audio Group Mode5 and a Master Audio Group Mode6, with

a balanced stereo audio output on a terminal block connector for each
group. In addition, in the AV Group you can select the audio-follow-video
input from each group for switching, and in the Master AV Group you can
convert the selected video input (one of 18) to the SCALED OUTPUTS,
and also route the selected audio input (one of 18) to the MASTER OUT
terminal block connector

 An independent Master Audio output that has a rich set of ProcAmp

features, including bass and treble controls (via the MENU and LCD status
display (and OSD when appropriate)), RS-232 and the infra-red remote
control transmitter

 Audio breakaway option (to switch audio independently from video) or

Audio-follow-video

 Adjustable volume on each input and output

 A microphone input that can be used by mixing, switching or talk-over

 Includes a front panel lock, as well as a separate OSD lock

 In addition to providing an up- or down- scaled output of the selected (one of

18) inputs, also functions as 4x1 switchers for each video group (2x1 for DVI)

 Has ProcAmp7 controls for the scaler output

 Lets you freeze the image at any instant

 Lets you select the output colorspace (RGB or YPbPr)

1 A method of security encryption (developed by Intel and Silicon Image)

2 An HDCP source would show up as a very snowy, noisy picture at the output

3 Selects the video input from each group: CV, YC, Component, VGA, DVI for switching to its local (group) output

4 Converts the selected input (one of 18) to the SCALED OUTPUTS

5 Selects the audio input from each group for switching

6 Routes the selected audio input (one of 18) to the MASTER OUT terminal block connector

7 Processing amplification enables adjustment of different video and audio signal parameters

Your VP-725DSA Presentation Switcher / Scaler

5

 Has a text overlay feature1 for insertion of subtitles, karaoke script, text

banners, and the like, which lets you send text to be displayed on the
scaled output

 Includes a built-in Picture-In-Picture (PIP) inserter2 (letting you insert a

video source into a graphics background or vice versa. This PIP image
may be positioned and sized anywhere on the screen, or displayed as 2
images side-by-side (Split-Screen)

The VP-725DSA:

 Comes in a rugged, professional 19" 3U rack-mountable metal enclosure

 Uses a universal 100-240VAC automatic power supply

Control the VP-725DSA:

 From the front panel user-friendly menu-driven OSD (see section 9.1)

 From the front panel high contrast LCD Display (see section 9.2)

 Remotely, from the infra-red remote control transmitter (see section 9.3)

 Via Ethernet (see section 9.4)

 Remotely, via RS-232

Achieving the best performance means:

 Connecting only good quality connection cables, thus avoiding

interference, deterioration in signal quality due to poor matching, and
elevated noise levels (often associated with low quality cables)

 Avoiding interference from neighboring electrical appliances, making

sure not to block the ventilation holes, and positioning your VP-725DSA
away from moisture, excessive sunlight and dust

5 Installing on a Rack

This section describes what to do before installing on a rack and how to rack
mount.

Before Installing on a Rack

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

Operating temperature range +5 to +45 Deg. Centigrade

Operating humidity range 5 to 65 % RHL, non-condensing

Storage temperature range -20 to +70 Deg. Centigrade

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 operating ambient temperature 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

position.

4 You do not overload 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 the appropriate
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 only to an electricity socket with
grounding. Pay particular attention to supply
connections other than direct connections to the branch
circuit (for example, the use of power strips), and that
you use only the power cord that is supplied with the
machine.

How to Rack Mount

To rack-mount the 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 Kramer 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)
