DVI DA2 and DVI DA 4 • User Guide

This guide describes the installation and operation of the Extron DVI DA2 and DVI DA4 Distribution Ampliers. Unless stated

otherwise, “distribution amplier” or “the unit” in this guide refer to both models.

About the DVI DA2 and DVI DA4

The Digital Visual Interface (DVI) Distribution Ampliers (DAs) have one input and either two (DVI DA2) or four (DVI DA4) outputs.

Output 1 for each model is for a local monitor and is used for Digital Display Channel (DDC) reference.

Both distribution ampliers accept one single link DVI-D input and drive two (DVI DA2) or four (DVI DA4) single link DVI-D output

signals.

DVI DA2 and DVI DA4 Features

• External power supply — The DVI DA2 and DVI DA4 are powered by an external 12VDC power supply (provided with the

units).

• DVI-D input — Both distribution ampliers accept one single link DVI-D input with a range of resolutions up to 1920 x 1200

or 1080p @ 60 Hz.

• Input equalization — Input Equalization (EQ) conditions the input signals to ensure the integrity of the signals delivered to

the output devices.

• DVI-D outputs — The units drive two (DVI DA2) or four (DVI DA4) single link DVI-D output signals.

• DDC routing to the local monitor — Output 1 is used as a DDC reference and is labeled “Local Monitor” for easy reference.

The video source uses the bidirectonal DDC to communicate with the local monitor, which allows the source to determine the

resolution and refresh rate of the signal that it sends.

NOTES:

• Since output 1 is used as the reference, all other display devices must be capable of handling resolutions equal to or

greater than that of the local monitor.

• The actual signal transmission distance can vary greatly and depends on signal resolution, cable type, cable quality,

graphics card, and the display used in the system.

• Versatile mounting options — Both units are 1U high, 3 inches (7.62 cm) deep, and 1/2rack (8.7 inches or 22.1 cm) wide,

allowing them to be conveniently mounted in a rack, mounted under a desk, or set on a tabletop.
