The DV-S4 “Sprite®” 4K Ultra High Definition media player can play UHD video up to full 4K@60 fps with HDMI output and also adds optical audio out and supports 5.1 surround sound. The DV-S4 also supports composite output for old PAL/NTSC, CRT monitors. It is slightly larger than the DV-S1 and uses only 2.5 Watts of power. It can be used as a simple repeater, looping a file when power is applied, or you can be in total control of the show. You can trigger a second file by pushbutton or voltage level change. Once the triggered file is completed the Sprite returns to the looping file. There is no blank space when looping or changing files. You can select multiple trigger options, and other initial setup options using the included remote control. Need more control? The Sprite 4K has a 2-way serial port. Use your favorite PLC, microprocessor or show controller and command the Sprite® to play up to 200 different files in any order, and at any time you want. Serial commands are backward compatible with the DV-S1.
