2 VP-725NA - 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
Use Kramer high performance high resolution cables
Use only the power cord that is supplied with this machine
Go to http://www.kramerelectronics.com 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 to avoid interference, deterioration
in signal quality due to poor matching, and elevated noise levels (often
associated with low quality cables)
•Avoid interference from neighboring electrical appliances that may
adversely influence signal quality
•Position your Kramer VP-725NA away from moisture, excessive sunlight
and dust

VP-725NA – Overview 3
3 Overview
The VP-725NA is a presentation scaler/switcher with multiple signal format sections
and balanced stereo audio. The unit has five independent 4x1 video sections:
composite, s-Video (Y/C), component (RGB), computer graphics, and HDMI, plus a
single USB input. Each section can be operated as an individual switcher contained in
one box. It also scales any of the 21 inputs 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.
In particular, the VP-725NA features include:
•Silicon Optix HQV® Video Processing (Hollywood Quality Video) which
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
•High-quality 3:2 and 2:2 pull down, de-interlacing and full up- and down-
scaling of computer graphics video input signals
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).
•HDTV Compatibility and HDCP compliance
The HDCP (High Definition Content Protection) license agreement allows copy-
protected data on the HDMI input to pass to the HDMI output only.
•Fade-Thru-Black (FTB™) Switching – The video fades to black and then
the new input fades from black for smooth, glitch-free 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 (see
Section 6.4)
•Multi-Formats – Auto, NTSC (3.58/4.43), PAL (M/N/60) and SECAM
•Scaled computer & HDTV outputs – A single output signal in three formats
(15-pin HD, RGBHV, and HDMI) simultaneously
•HDTV output resolutions – 720p, 1080i, and 1080p

4 VP-725NA - Overview
•A USB port on the front panel for reading and displaying JPEG picture files
•Multiple color space – RGB or YUV output
•Embedded audio on the HDMI inputs and outputs
The embedded audio feature is not available for the RGB resolutions 1920x1200 and
1920x1080. (It is available for 1080p)
•HDMI channel support of up to 2.25Gbps bandwidth per graphic channel
Suitable for resolutions up to UXGA at 60Hz, and for all HD resolutions.
•Projector Anywhere™ technology – horizontal & vertical geometry controls
that compensate for off-axis projector placement
•A wide choice of computer graphics output resolutions up to
WUXGA/1080p, plus user-definable custom output resolutions with
selectable refresh rates
Recommended for advanced users only – non-standard settings may not be
recognized by the display device.
•Multiple aspect ratio selections: standard, letterbox, follow output, virtual
wide, follow input, and user definable settings
•Six possible operation modes via the Video Group, the Audio Group, the
Scaler and the Master Audio buttons.
These modes function simultaneously and independently, letting you switch
the audio and video signals separately (breakaway mode) or in the audio-
follow-video mode
VIDEO GROUP – selects the video input from each group: CV, YC, COMP, UXGA,
HDMI for switching to its local (group) output
AUDIO GROUP – selects the audio input from each group for switching
SCALER MODE – converts the selected input (one of 21) to the SCALED OUTPUTS
MASTER AUDIO MODE - routes the selected audio input (one of 20) 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, LCD status
display, OSD, RS-232 and the infrared remote control transmitter)
•An adjustable volume on each input and output
•A microphone input that can be used by mixing, switching or talk-over
•Built-in ProcAmp: color, hue, sharpness, contrast, and brightness are set
individually for each input
•A built-in time base corrector that stabilizes the sync in unstable video
sources

VP-725NA – Overview 5
•A built-in TBC (time base corrector) that stabilizes the sync in unstable
video sources
•A slideshow feature, letting you run a slideshow via the USB port
•Front panel freeze frame
•Video blanking, with a selectable blue or black screen
•Screenshot capture
In addition, the VP-725NA:
•Scales and zooms (to up to 400% of the original size)
•Can be firmware upgraded in the field via the USB port on the front panel
•Includes worldwide power supply – 100-240V AC on a standard 19” rack
mount size, 3U Rack "ears" included
•HDMI channel supports up to 2.25Gbps bandwidth per graphic channel
Suitable for resolutions up to UXGA at 60Hz, and for all HD resolutions.
Control the VP-725NA from the front panel and a user-friendly menu-driven OSD
(see Section 7.1), or:
•From the front panel high contrast LCD Display (see Section 7.2)
•Via the Ethernet (see Section 7.3)
•Remotely, from the infrared remote control transmitter (see Section 7.4)
•Remotely, via RS-232 (see Section 5.3)
3.1 11BDefining EDID
The Extended Display Identification Data (EDID) is a data-structure provided by a
display, to describe its capabilities to a graphics card (that is connected to the
display’s source). The EDID enables the VP-725NA to “know” what kind of monitor
is connected to the output. The EDID includes the manufacturer’s name, the
product type, the timing data supported by the display, the display size, luminance
data and (for digital displays only) the pixel mapping data.
EDID is defined by a standard published by the Video Electronics Standards
Association (VESA).
