Kramer Electronics VP-725DSA VP-725DS and VP-725DSA are presentation scaler/switchers with multiple signal format sections with the VP-725DSA adding balanced stereo audio for each input. The unit has 5 sections: a 4x1composite video section, a 4x1 s-Video (Y/C) section, a 4x1 component video (YUV) section, a 4x1 computer graphics video section and a 2x1 DVI video section - that can be operated as unique individual switchers contained in one box. Also any one of the 18 inputs can be scaled to a single graphics or HDTV output resolution on the three scaled output connectors comprised of an HD-15F connector, 5 BNC connectors and a DVI connector simultaneously. K-Storm Scaling Technology – Kramerfeets extremely high performance scaling technology. High quality 3: 2 and 2:2 pull down de-interlacing and full up and down scaling of computer graphics video input 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-ITT Picture-in-Picture Image Insertion Technology - Ultra stable picture-in-picture image insertion capability. Any video source can be inserted into a computer graphics video source and vice versa with positioning and sizing controls. A unique splitscreen mode (2 images side-by-side) is also available. 6 Switchers in 1 - Five dedicated signal formats: a 4x1 Composite, 4x1 s-Video (YC), 4x1 Component (RGB/YUV), 4x1 Computer Graphics (HD-15F), and a 2x1 DVI-D (on a DVI-I connector). One 18x1:3 scaled output. Scaled Computer and HDTV Outputs - A single output signal in 3 formats (HD-15, 3 BNCs, and DVI-D) simultaneously. Multiple Computer Graphics Output Resolutions - including a user-defined output resolution with selectable refresh rates. HDTV Output Resolutions - 480p, 720P and 1080i in component format on all 3 scaled outputs simultaneously with selectable refresh rates. Audio (VP-725DSA) - Balanced stereo Audio inputs for all 18 inputs plus Balanced stereo Audio outputs for all 5 dedicated signal format outputs and one for the scaled output. Multi-Standard - PAL, SECAM, and NTSC (3.58/4.43). Multiple Aspect Ratio Selections - 4x3 or 16x9, anamorphic, letter box, and user definable settings. HDTV Compatible Component Input. Built-in Time Base Corrector - Stabilizes video sources with unstable sync. Multiple Color Space - Output RGB or YUV (Selectable). Built-in Proc-Amp - Color, hue, sharpness, contrast, and brightness are set individually for each input. Mic Input (VS-725DSA) - Condenser or Dynamic with talk over, mix and override controls. Front Panel Lockout. Freeze Frame. Audio Mute. Video Blanking - Blue or black screen. Zoom (100 percent to 400 percent). Flexible Control Options - Front panel buttons, IR Remote (with on-screen menus) and RS-232. Worldwide Power Supply - 100-240V AC. Standard 19inch Rack Mount Size - 3U.
