DVI DA2 and DVI DA 4 • User Guide
This guide describes the installation and operation of the Extron DVI DA2 and DVI DA4 Distribution Ampliers. Unless stated
otherwise, “distribution amplier” or “the unit” in this guide refer to both models.
FCC Class A Notice
This equipment has been tested and found to comply with the limits for a Class A digital device, pursuant to part15 of the
FCC rules. The ClassA limits provide reasonable protection against harmful interference when the equipment is operated in a
commercial environment. This equipment generates, uses, and can radiate radio frequency energy and, if not installed and used
in accordance with the instruction manual, may cause harmful interference to radio communications. Operation of this equipment
in a residential area is likely to cause interference. This interference must be corrected at the expense of the user.

About the DVI DA2 and DVI DA4
The Digital Visual Interface (DVI) Distribution Ampliers (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 ampliers 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 12VDC power supply (provided with the
units).
• DVI-D input — Both distribution ampliers 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 1/2rack (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.
Installation Overview
Both distribution ampliers can be placed on tabletops, or mounted under furniture or in racks by following these steps:
1. Turn off all electrical equipment. Make sure that the input sources, the DA and the output display(s) are all turned off and all
power sources and signal cables are disconnected.
2. Mount the unit (see page 5).Mounting
3. Connect the cables (see on page 3).DVI Connections
4. Plug in the (see page 3), then turn on the display devices and input devices.power supply

NOTES:
• The length of the exposed wires in the stripping process is critical.
The ideal length is 3/16 inch (5 mm).
• If the exposed section is , the exposed wires may touch, longer
causing a short circuit between them.
• If it is , the wires can be easily pulled out, even if tightly shorter
fastened by the captive screws.
• Do not tin the wires. Tinned wire does not hold its shape and can
become loose over time.
Figure 4. Power Connection
ATTENTION:
• This product is intended to be supplied by a Listed Power Unit marked “Class 2” or “LPS,” rated 12 VDC, maximum
1.0 A. Always use a power supply supplied or specied by Extron. Use of an unauthorized power supply voids all
regulatory compliance certication and may cause damage to the supply and the end product.
• Unless otherwise stated, the AC/DC adapters are not suitable for use in air handling spaces or in wall cavities. The
power supply is to be located within the same vicinity as the Extron AV processing equipment in an ordinary location,
Pollution Degree 2, secured to the equipment rack within the dedicated closet, podium, or desk.
• The installation must always be in accordance with the applicable provisions of National Electrical Code ANSI/NFPA70,
article 75, and the Canadian Electrical Code part 1, section 16. The power supply shall not be permanently xed to
building structure or similar structure.

c — Connect up to two (DVI DA2) or four (DVI DA4) DVI-D outputs to display devices, using the female DVI Output connectors
connectors.
NOTE: The outputs are not HDCP compatible.
d — Output 1 (Local Monitor) is used as a Hotplug Detect, a DDC clock, and a DDC data reference. Local Monitor connector
For the input device to provide a signal at the correct resolution and refresh rate, there must be a display device connected to
output1.
NOTE: Although the source device, local monitor, and remote display devices all connect to the distribution amplifiers
through DVI-I connectors, the DVI DA2 and DVI DA4 are compatible only with single-link DVI-D video signals.
To enable the units to accept sources providing HDMI signals or to provide signals to displays that accept HDMI signals,
use a HDMI to DVI adapter or cable, such as the Extron HDMIF-DVIDM female HDMI to male DVI-D adapter or the Extron
HDMIM-DVI-D M series of male HDMI to male DVI cables.
The input signal is one single link DVI-D with a resolution range up to 1920x1200 or 1080p@ 60 Hz.
Input EQ conditions input signals to ensure the integrity of the signals delivered to the output devices.
NOTES:
• The actual signal transmission distance can vary and depends on the signal resolution, cable quality, graphics card, and
display used in the system.
• To ensure proper operation, display devices connected to outputs 2 through 4 must be able to handle resolutions equal
or greater than that of the local monitor on output 1.
