克莱默KRAMER-演示切换器/倍线器-VP-725DS

The 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, a4x1 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 oneof 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 connectorsimultaneously.
K-Storm™ Scaling Technology – Kramer’s 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 (Y/C), 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 & 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 ***able refresh rates.
HDTV Output Resolutions - 480p, 720P and 1080i in component format on all 3 scaled outputs simultaneously with ***able 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.
