1.0 INTRODUCTION
Thanks for purchasing this 1T-DA-726 3G/HD/SD-SDI Distribution Amplifier with Reclocking
from tvONE. The 1T-DA-726 3G/HD/SD-SDI Distribution Amplifier provides 6 outputs from a
single SDI input for distribution to devices capable of receiving and/or displaying such
signals. The 1T-DA-726 3G/HD/SD-SDI Distribution Amplifier provides third generation
HD/SD signal distribution with triple-rate processing and six separately buffered and
reclocked outputs. Automatic input cable equalization up to 300m (1000ft)@SD,
150m(500ft)@HD and 100m(325ft)@3G is provided and all ancillary data is passed through
to the outputs. Since the SDI signals are reclocked, multiple 1T-DA-3G/HD/SD-SDI
Distribution Amplifiers can be cascaded for longer transmission runs.

1.3 Getting the Best Results
There are many factors affecting the quality of results when distributing SDI type signals.
Some basic precautions will ensure the best possible performance from your new
1T-DA-726 3G/HD/SD-SDI Distribution Amplifier.
Output display device –The quality of the output signal will depend largely upon
the type and quality of the SDI display device used. For instance, some video
projectors just look better than others.
Distance between the DA sources and the display –This plays a major role in the
final result. Long distances are possible, but special measures should be taken in
order to avoid cable losses. These include using high quality cables. Line
amplifiers may also be necessary for the longest runs.
Input/Output connection cables –Low quality cables are susceptible to
interference. They degrade signal quality due to poor matching and can cause
elevated noise levels. Cables should be of the best quality.
Interference from nearby electrical devices –These can have an adverse effect
on signal quality. For example, an older computer monitor often emits very high
electromagnetic fields that can interfere with the performance of video equipment
in its proximity.

3.0 PACKAGE CONTENTS
Before attempting to use this unit, please check the packaging and make certain the
following items are contained in the shipping carton:
1x 1T-DA-726 1x6 3G/HD/SD-SDI Distribution Amplifier
1x 100~240VAC to 5VDC Power Adapter
1x Instruction Manual
NOTE: Please retain the original packing material should the need ever arise to return the unit. If you find any items are
missing, contact your reseller or tvONE immediately. Have the Model Number, Serial Number and Invoice available for
reference when you call.
4.0 CONNECTING THE HARDWARE
Connect the SDI Video Source to the input of the 1T-DA-726 3G/HD/SD-SDI Distribution
Amplifier, connect its outputs to appropriate SDI devices or monitors and lastly connect
the AC to DC Power Adapter. The drawing below shows the locations of the input,
outputs and power connector.
4.1 Connecting the Input to the Distribution Amplifier
You can connect any SDI compliant device’s output to the 1T-DA-726 3G/HD/SD-SDI
Distribution Amplifier’s input. Make certain that the SDI cable is securely plugged into the
source device as well as the 1T-DA-726 3G/HD/SD-SDI Distribution Amplifier. Always use a
high quality cable, as short a length as possible, for best results.
4.2 Connecting the Outputs to the Destination Devices
Using a high quality SDI cable, connect each output of the 1T-DA-726 3G/HD/SD-SDI
Distribution Amplifier to an SDI compliant device. Use the shortest cable run possible.
4.3 Connecting Power
The 1T-DA-726 3G/HD/SD-SDI Distribution Amplifier is shipped with a Power Adapter to
convert 100-240VAC@50-60Hz to 5VDC. Connect the DC Output Cable from the Power
Adapter to the unit and then plug the Power Adapter into an AC Receptacle. There is no
power switch. The unit begins to function as soon as it is plugged into AC.

5.0 OPERATING THE UNIT
Once the input, output and power cables are connected, plug the AC adaptor into the AC
receptacle and the 1T-DA-726 3G/HD/SD-SDI Distribution Amplifier will begin to function. A
Power LED on the unit will confirm power is present. A second LED will indicate that a valid
SDI input signal is present and the 1T-DA-726 3G/HD/SD-SDI Distribution Amplifier has
locked to the signal. Other than connecting cables and applying power, there are no
operator interventions required.
6.0 TROUBLESHOOTING
In the event of problems, first make certain that the input and output cables are no more
than the specified lengths for the type of SDI signal being distributed and are of the
highest possible quality. Next, make certain that the 1T-DA-726 3G/HD/SD-SDI Distribution
Amplifier is receiving power.
If you experience problems using the 1T-DA-726 3G/HD/SD-SDI Distribution Amplifier, you
should attempt to determine what is wrong by attaching the source device directly to the
destination device using the same cables you are using with the expanded system. Use
first the source cable and then the destination cable. This is a way of determining if the
problem is due to bad cables or a problem with the other devices. If you are unable to
obtain a signal using this simplified path, suspect the cables, the source device or the
destination device.
Note: It is strongly recommended that you use premium cables in order to achieve
maximum distance cable runs and the best performance possible.
After trying the above suggestions should the problem still persist, contact your dealer for
additional suggestions before contacting tvONE. Should the dealer’s technical personnel
be unable to assist you, contact tvONE via our support website:
http://tvone.crmdesk.com. Create a technical support request on the site and our support
team will respond within a short period of time.
