The Kramer 725XLA ProScale Presentation Scaler/Switcher (21-Input), with balanced stereo audio, is used to upscale or downscale 5 (4x1) independent video sections, composite, s-Video (Y/C), component video (YUV), HDMI, computer graphics video, and JPEG files to a selectable computer graphics video or HDTV output resolution. This output signal is available simultaneously in 3 formats such as HDMI, 15-pin HD or 5 BNC. It supports HDTV output resolutions up to 720p, 1080i, and 1080p.

Embedded with the HQV (Hollywood Quality Video) processing, the ProScale Presentation Scaler/Switcher (21-Input) offers high-quality de-interlacing (including 3:2 & 2:2 pull down), noise reduction, and scaling performance for standard-definition and high-definition signals. With the FTB (Fade-thru-Black) switching technology, the switcher offers smooth transition between sources by fading out 1 video input to black, and the new input fades in from black. The output signal provides constant sync so the display never glitches, and allows for smooth operation.

Being HDCP (High-definition Content Protection) compliant, the 21-Input Scaler/Switcher prevents unauthorized tampering of HDMI output, and transfers signals to the preferred HDMI output. The device is HDTV compatible and has a single USB input for importing JPEG files.

The ProScale Presentation Scaler/Switcher features a PiP (picture-in-picture) inserter that uses the K-IIT XL image insertion technology to view video and graphic sources simultaneously on the same window as picture-in-picture or a split screen. It allows you to insert and align any video source next to a computer graphics video source or vice versa, with window positioning and sizing controls.
