Frequently Asked Questions - DAC-70 DataVideo

How do I select the input source using the DIP switches?

Use DIP switches 1 and 2 on the rear panel. Set them to 00 for VGA, 01 for HDMI, 10 for SDI, or 11 for PC (disables DIP switch).

Can the DAC-70 pass HDCP protected content?

No, the DAC-70 outputs no signal when HDCP protected video (e.g., from DVD or Blu-ray) is supplied to the HDMI input.

How do I update the firmware on the DAC-70?

Connect the unit to a Windows PC via Micro-USB 2.0, power on while running the Datavideo Upload Firmware utility, select the firmware file, and click Start. The process takes about 10 minutes.

What is the maximum video output resolution supported?

The DAC-70 supports output resolutions up to 1080p60 via both HDMI and SDI interfaces.

Can I adjust picture parameters like brightness and contrast?

Yes, via the Proc Amp tab in the DAC-70 Center Utility. You can adjust Brightness, Contrast, Hue, and Saturation from 0 to 255.

How do I reset the DAC-70 to factory defaults?

In the DAC-70 Center Utility, click the Setting tab and then the Factory Default button. This resets all settings to their original values.

What audio formats can the DAC-70 handle?

The DAC-70 supports embedded PCM audio up to 8 channels at 48 kHz. It also accepts external stereo analog audio via RCA inputs at line level.

Can I use external analog audio instead of embedded HDMI/SDI audio?

Yes, connect an analog stereo source to the RCA L/R inputs on the front panel. Select EXT (external) via DIP switch 3 or set Audio Source to External in the utility.

How can I mount the DAC-70 in a 19-inch rack?

Use the optional RMK-2 rack mount kit, which allows mounting one or two DAC-70 units side by side in a standard 19-inch rack.

What should I do if no video signal appears on the output?

Check the input source and ensure it is not HDCP protected. Verify DIP switch settings. In the utility, check the No Signal Mode setting – it can be set to Black Screen or other options. Also confirm the output format matches your display.

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!
