The VP-725DSA 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, SVGA, XGA, SXGA and UXGA; HDTV (480p, 720p and 1080i); and several optimum plasma and LCD rates such as 1365 x 1024, 1366 x 768 and 1024 x 852. The unit also offers 3:2 and 2:2 pull-down. The VP-725DSA 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). In addition to providing an up- or down- scaled output of the selected (1 of 18) inputs, the machine also functions as 4 x 1 switchers for each video group (2x1 for DVI). The unit has ProcAmp controls for the scaler output; the image can be “Frozen” at any instant; and the output colorspace can be selected (RGB or YPbPr). The unit also has a text overlay feature for easy insertion of subtitles, karaoke script, text banners, etc. In addition, the unit includes a Picture-In-Picture (PIP) inserter for insertion of any 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 has all the features of the VP-725DS in addition to a full set of audio features. The VP-725DSA has a stereo balanced audio input corresponding to each of the 18 video inputs; and similarly for the group outputs. Also, there is an independent Master Audio output. Switching of the audio may be done independently of the video (audio-breakaway), or Audio-Follow-Video operation may be selected. The user can adjust the volume on each input and output; and the Master output has a rich set of ProcAmp features, including bass and treble controls. In addition, the user may use a microphone input, either by mixing, switching or talk-over. Control of the unit may be via a user-friendly menu-driven OSD and/or a high contrast LCD, RS-232, an IR remote control and Ethernet. The unit is housed in a rugged, professional 19” 3U rack-mountable metal enclosure and uses a universal 100-240VAC automatic power supply.
