1. Introduction

The Datavideo DAC-70 is a broadcast quality up/down/cross converter. The unit
allows the user to configure the device using a simple DIP switch or on a USB 2.0
interface utility. The DAC-70 case LEDs indicate the currently selected video
source. The DAC-70 gives the user the capability of sharing VGA, HDMI or SDI
inputs in an HDMI or SDI environment.

Housed in a metal case, the DAC-70 is tough enough to withstand the knocks of
fast-paced live production setups in ENG or any studio. Built to the same

dimensions as Datavideo’s range of converters, the DAC-70 can also be
mounted into a standard 19” RMK-2 rack with a mix of other units.

That’s Datavideo, sharing the value!
