VP−733 is a 12−input Presentation Matrix Switcher/Dual Scaler for a wide variety of presentation and multimedia applications. VP−733 has HDMI, DisplayPort, HDBaseT and user−definable (universal) analog video inputs (each can be set as computer graphics, composite video, s−Video (Y/C) or component video). It up−scales or down−scales to selectable output resolutions up to 4K and provides glitch−free switching between sources through fast FTB™ (fade−thru−black) switching technology. Independent Program and Preview outputs are available simultaneously, or the unit can be configured for PIP, with all outputs mirrored. Outputs are available on two HDMI connectors, an HDBaseT, a DP, and a 15−pin−HD computer graphics video connector. Rich audio support is also included, with digital audio embedding and de−embedding, as well as 10 analog stereo inputs and analog, S/PDIF, and speaker outputs.
