Version 3 of the DECIMATOR MD-QUAD 3G/HD/SD-SDI Quad Split Multi-Viewer with SD/HD/3G-SDI & HDMI Outputs adds a test pattern generator, audio tone generator, audio channel pass through, and on-screen display on an optional connected monitor. The device provides you with an SD/HD/3G-SDI quad splitter or multiplexer. It features four auto detecting SDI inputs, and outputs to an SDI and an HDMI output. Each input is independent and features low latency buffering, which allows the device to display all four inputs on an optional monitor screen simultaneously, even when each input signal is a different format or frame rate. The output signal also supports different aspect ratios being displayed on the screen of your monitor's SDI or HDMI input. A rotary encoder and push button selector allows you to navigate and select from the menu option without setting DIP switches or connecting to a computer. The menu function allows you to select your output format, and a locking power socket minimizes the chance of power loss by a kick out of the power cable.
