Introduction
About This Manual
This manual describes the installation, operation, and
specifications of the Extron DVI DA2 and DVI DA4 Distribution
Amplifiers.
Unless stated otherwise, all references to the "distribution
amplifier" or "the unit" in this manual refer to the features or
operation of both models.
About the DVI DA2 and DVI DA4
The Digital Visual Interface (DVI) Distribution Amplifiers (DAs)
have one input and either two (DVI DA2) or four
(DVI DA4) outputs.
Both distribution amplifiers accept one single link DVI-D input
and drive two (DVI DA2) or four (DVI DA4) single link DVI-D
output signals.
In both models, Output 1, is used for Digital Display Channel
(DDC) reference.

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 amplifiers accept one single
link DVI-D input, with a resolution range 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 Output" 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.
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.
N
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.
N
Versatile mounting options — Both units are 1U high, 3"
(7.62 cm) deep, and 1/2 rack (8.7" or 22.1 cm) wide, allowing
them to be conveniently mounted in a rack, under a desk or set
on a tabletop.

Installation and Operation
Installation Overview
Both distribution amplifiers can be mounted on tabletops, under
furniture, and 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 as described in "Mounting the Distribution
Amplifier", below.
3.
4.
Connect the Cables (see "Cable Connections" on page 2-8).
Plug in the power supply, then turn on the display devices
and input devices (see "Operation" on page 2-11).
Mounting the Distribution Amplifier
The 1 U, half rack size of the distribution amplifiers allows them
to be mounted in racks, under furniture or on tabletops.
Tabletop placement
Attach the four provided rubber feet to the bottom of the unit
and place it in any convenient location.
Rack mounting
UL guidelines for rack mounting
The following Underwriters Laboratories (UL) guidelines are
relevant to the safe installation of these products in a rack:
1.
Elevated operating ambient temperature — If the unit
is installed in a closed or multi-unit rack assembly, the
operating ambient temperature of the rack environment
may be greater than room ambient temperature. Therefore,
install the equipment in an environment compatible with
the maximum ambient temperature (Tma: +122 °F, +50 ° C)
specified by Extron.
2.
3.
4.
Reduced air flow — Install the equipment in the rack
so that the equipment gets adequate air flow for safe
operation.
Mechanical loading — Mount the equipment in the rack
so that uneven mechanical loading does not create a
hazardous condition.
Circuit overloading — Connect the equipment to
the supply circuit and consider the effect that circuit
overloading might have on overcurrent protection and
supply wiring. Give appropriate consideration to the
equipment nameplate ratings when addressing this
concern.

5.
Reliable earthing (grounding) — Maintain reliable
grounding of rack-mounted equipment. Pay particular
attention to supply connections other than direct
connections to the branch circuit (such as the use of power
strips).

1.
Use a DVI cable to connect the source device to the female
DVI-I input.
Although DVI-I connectors are used, these distribution
amplifiers are only compatible with single-link DVI-D
video signals.
N
For sources providing HDMI signals, use a HDMI to DVI
adapter or cable, such as the Extron HDMIF-DVIDM
female HDMI to male DVI-D adapter (#26-616-01) or the
Extron HDMI M-DVI-D M series of HDMI male to DVI
male cables (#26-614-xx).
The input signal is one single link DVI-D with a resolution
range up to 1920 x1200 or 1080p @ 60 Hz.
Input EQ conditions input signals to ensure the integrity of
the signals delivered to the output devices.
2.
Use DVI-I cables to connect up to four display devices.
To output a HDMI signal, use a HDMI to DVI adapter,
such as the Extron HDMIF-DVIDM female HDMI to male
DVI-D adapter (#26-616-01).
The actual signal transmission distance can vary and
depends on signal resolution, cable quality, graphics
card, and display used in the system.

Troubleshooting
No output signal — Check that the front panel LED is on (lit
green). If it is not, check the power supply connections to the
unit (see page 2-10).
No output signal or poor quality signal — Check the integrity
of the cabling to output 1 and ensure that output 1 (Local
Monitor) is connected to the distribution amplifier before
powering on the source device.
If the source device cannot communicate with output 1 when it
is being powered on, it may not be able to send a video signal or
the signal may have the wrong resolution or refresh rate.
No output signal or poor quality signal — Check the input
and output cabling (see page 2-8). DVI signals run at very high
frequency and poor connections can cause degradation or loss of
the signal, or jitter. To avoid this:
•
•
Use only cable that is designed for DVI signals.
Limit or avoid the use of adapters.
Display device displays a flashing black or blue screen, snow
or other distortion — A device that is not HDCP compliant may
be receiving HDCP-encrypted signals.
The DVI DA2 and DVI DA4 are not High-Bandwidth Digital
Content Protection (HDCP) compliant. They will only pass
HDCP-encrypted signals to the local output device.
Signal on local monitor but not on other displays — Check
that all output devices (monitors or projectors) can handle
resolutions equal to or greater than that of the local monitor.
