1 Introduction Welcome to Kramer Electronics! Since 1981, Kramer Electronics has been providing a world of unique, creative, and affordable solutions to the vast range of problems that confront the video, audio, presentation, and broadcasting professional on a daily basis.
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 i 2.1 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).
3 Overview The Kramer VP-728 is a 9-input Proscale™ Presentation Switcher / Scaler with unbalanced stereo and digital S/PDIF audio. The VP-728 scales any composite, s-Video (Y/C), component video (YUV), HDMI or computer graphics video signal, as well as JPEG files (via USB) up or down to a selectable graphics or HDTV output resolution.
• 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 - four (stereo audio or S/PDIF on two RCA connectors) for each of the four universal video inputs; two unbalanced stereo audio (on 3.
In addition, the VP-728: • 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 • Scales and zooms (to up to 400% of the original size) • Can provide non-linear scaling for 4

4 Installing in a Rack This section provides instructions for rack mounting the unit.
5 Connecting the VP-728 i Always switch off the power to each device before connecting it to your VP-728. After connecting your VP-728, connect its power and then switch on the power to each device. To connect the VP-728 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.
3. Connect the video outputs: The HDMI OUT connector to an HDMI acceptor (for example, a plasma display) The UXGA OUT 15-pin HD computer graphics video connector to a video acceptor (for example, an analog display) 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 L and R unbalanced stereo audio output and/or the S/PDIF digital audio output to audio acceptors, for example, power amplifiers. 5.
Figure 3: Connecting to the VP-728 Rear Panel 12 VP-728 - Connecting the VP-728
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 2 to pin 3, pin 3 to pin 2, and pin 5 to pin 5 need be connected) to the RS-232 9-pin D-sub port on the PC. Note: There is no need to connect any other pins.
6 Presentation Switcher / Scaler Buttons The VP-728 includes the following front panel buttons: 6.1 • Nine INPUT selector buttons • A PIP button • BLANK and FREEZE buttons • Six OSD buttons • A RESET TO XGA/720p button • A PANEL LOCK button Switching an Input Each INPUT SELECTOR button can be used to select the source. When selected, the button illuminates. You can switch seamlessly between each input that is connected to a source by pressing the appropriate INPUT SELECTOR button.
6.2 The PIP Button Feature The Picture-in-Picture inserter (PIP) uses K-IIT XL™ image insertion technology to present video and graphic sources simultaneously so that you can display: • An inserted video source PIP over a graphic source background • An inserted graphic source PIP over a video source background VIDEO SOURCE – can be composite or s-Video GRAPHIC SOURCE – can be HDMI, UXGA or component For example, you can show a live video window on top of a graphic background and vice versa.
6.2.2 Selecting the PIP Source To easily select the PIP source, press and hold the PIP front panel button while pressing the input button of the required PIP source. For example, to select UXGA 2 as the graphic PIP source over a video background, press the PIP front panel button while pressing the UXGA 2 front panel button. To select the PIP source using the IR remote controller, press the desired PIP source on the remote controller.
To replace a PIP source in the same category (for example, changing the PIP source from HDMI 2 to HDMI 1), press the required PIP Source on the remote control transmitter and the PIP display will change accordingly. i 6.2.3 When attempting to select a PIP source of the same category as the background source (for example, video on video, which is not compliant with the table on Page 18), a message is displayed, “Unavailable Operation”.
To replace a PIP in the same input signal category (for example, changing from UXGA 1 to HDMI 2), press the button for that PIP Source on the remote control transmitter and the PIP display will change accordingly.
6.3 Locking and Unlocking the Front Panel To prevent changing the settings accidentally or tampering with the unit via the front panel buttons, lock your VP-728. Unlocking releases the protection mechanism. When the front panel is locked, control is still available via RS-232. To lock the VP-728: • Press the PANEL LOCK button on the front panel. The front panel is locked and the PANEL LOCK button is illuminated.
6.4 The Infrared Remote Control Transmitter You can control the VP-728 remotely from the infrared remote control transmitter which is powered by two AAA size 1.5V DC batteries.
7 Configuring the VP-728 via the OSD MENU Screens The VP-728 uses an on-screen display (OSD) menu for system configuration. The menu appears as an overlay over any images that are output from the VP-728. There are eight sub-menus that are used to configure the VP-728. You can activate and navigate these menus from the front panel buttons, or from the IR remote control.

7.1.1 Reading JPEG Files You can read the JPEG files via the USB input. The JPEG files can be used to display a JPEG image, download a new Logo or background (see Page 33) or create a slideshow (see Section 7.7.1). To read JPEG files: 1. Load the JPEG images (the JPEG file should be smaller than 1MB and should not exceed a resolution of 2048x1536) to the route directory of a USB memory stick. 2. Connect the Memory stick to the USB connector on the front panel. 3.
7.2 The Picture Screen The Brightness, Contrast, Color and Hue picture settings are saved individually for each input (except USB).
