The Datavideo DAC-60 HD/SD-SDI to VGA Converter converts SD/HD/3G-SDI video signals into VGA signals for display on computer peripherals such as projectors and monitors. The DAC-60 features a loop-through input that passes the SDI input signal downstream without changing it. This allows you to feed the same video signals to both VGA and SDI based equipment. The unit auto detects the input format and scales it to the user selected VGA output format, which is indicated by the six LEDs.With the included software you can set the built-in processing amp (proc amp) to adjust Contrast, Hue and Saturation of the VGA signal. The SDI loop-through signal is unaffected by the proc amp settings. The unit is designed to be portable as it draws only 500 mA at 12 volts and weighs less than a pound.
