Presentation Powerhouse ? The DVI-3580a is a high-performance 4K MultiViewer, Presentation Switcher and Scaler. This unit is an ideal solution for system designers and facility managers facing uncertain requirements from presenters that need AV signal distribution for a diverse range of source devices, resolutions and signal formats. The DVI-3580a overcomes these challenges through a rich array of input connections that supports all popular AV input signal formats, a range of user-selectable output resolutions and innovative MultiViewer capabilities. These features provide the power and flexibility needed to adapt to the ever-changing demands of presentation rooms, classrooms, auditoriums, conference rooms, houses of worship, and other media-rich AV environments. Versatile Video Capabilities ? This powerful presentation switcher accepts up to seven (7) video inputs: 4x HDMI (or DVI), 2x DisplayPort and 1x RGB/YPbPr Analog (VGA). The unit supports a broad range of input signal formats and resolutions up to 4K /60p. A powerful internal scaling engine provides a range of user-selectable output resolutions up to 3840x2160 /30p, as well as seamless switching(1) of input signals. The selected input signal is routed to two mirrored outputs, 1x HDMI and 1x HDBaseT™. The HDBaseT output is POH (Power over HDBaseT) compliant, so a compatible receiver unit may be remotely powered from the DVI-3580a unit over the HDBaseT link. The MultiViewer function can simultaneously display up to 4x video signals with resolutions up to 4K, which are displayed in seven possible layouts: Single, Double, Triple, Quad 1, Quad 2, Quad 3, or Quad 4. Any input signal can be displayed in any MultiViewer window.
