·
Do not place heavy objects on top of the
DA1226AT. If the DA1226AT is to be
mounted to a table or wall, use only Altinex
made mounting accessories (Rack Mount
Ears DA1292FC) and cables for optimum
setup.
PRECAUTIONS / SAFETY WARNINGS
1
Please read this manual carefully before using your
DA1226AT Distribution Amplifier. Keep this manual
handy for future reference. These safety
instructions are to ensure the long life of your
DA1226AT and to prevent fire and shock hazard.
Please read them carefully and heed all warnings.
·
To turn off the main power, be sure to
remove the cord from power outlet. The
power outlet socket should be installed as
near to the equipment as possible, and
should be easily accessible.
1.1 GENERAL
·
·
Unauthorized personnel shall not open the
unit since there are high-voltage
components inside.
·
·
Do not pull power cord or any cable that is
attached to the DA1226AT Distribution
Amplifier.
If the DA1226AT Distribution Amplifier is not
used for an extended period of time,
disconnect the power cord from the power
outlet.
Qualified Altinex service personnel, or their
authorized representatives must perform all
service.

ABOUT YOUR DISTRIBUTION AMPLIFIER 2
The DA1226AT is a 1-in 6-out RGBHV distribution
amplifier designed to allow the connection of a
single computer video or interface source to as
many as six monitors or projectors capable of
handling the source resolution.

The DA1226AT offers excellent bandwidth
performance (minimum 350 MHz) and a typical
bandwidth of nearly 450 MHz, allowing it to remain
virtually transparent to high resolution signals.

(Y/C), and Composite Video by using the
appropriate channels. The DA1226AT outputs the

The DA1226AT offers a low-profile design, which
helps to prevent tilting due to cable drag when
used in desktop applications. The DA1226AT uses

Step 1.
Step 2.
Please attach the Interface on the rack
or table using the optional hardware.
The DA1226AT may be used with either
110V or 220V and offers a universal IEC
connector for ease of use throughout
the world. Before plugging in the power
cord to the unit, please verify that the
voltage rating of 110V/220V on the
FUSE CLIP located at the rear of the
unit is the same as the voltage rating on
the power outlet. To change setting,
unplug the power cord from the
DA1226AT and squeeze the clips on
either side of the fuse box. Then turn

You may have to use an
interface with your source to provide the
appropriate signal format type for
DA1226AT or to use a local monitor if
needed.

·

·
Please make sure that the input amplitude of
the analog signal is less than 1.5V.
Please make sure that sync levels at the
TTL level are between 1.4 Vp-p and 5 Vp-p.
Buffered output means that
the output signal is isolated
from the input signal. The
loaded output does not
affect the input, or any other
output on the device. A
buffered output may vary in
terms of the gain or peaking
adjustments made to the
video signal.
Please make sure that the highest quality of
cables is used. We recommend Altinex
made cables for best results.
·
If a problem arises after continuous usage at
a higher voltage, higher temperature, higher
humidity, or at other extreme environmental
conditions, please correct the problem.
NOTE: The sync pulse voltage must be at
least 1.4 V for proper operation of the
distribution amplifier. If lover voltage is used,
contact Altinex for additional information.

capable of driving signals to the DA1226AT
through the length of the cable.

Can I use

coaxial
cables?
You can’t use cat 5 cable
instead of coaxial cable,
because you will loose
quality of the receiving
signal. Since there is no
isolation of the signal in each
wire, the signals will interfere
with each other, so CAT-5 is
not recommended at all.
