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. Though primarily designed to pass an RGBHV signal format, the DA1226AT can also pass RGBS, RGsB, Component Video (Y, R-Y, B-Y), S-Video (Y/C), and Composite Video by using the appropriate channels. The DA1226AT outputs the same sync level as it receives on its input. The DA1226AT offers a low-profile design, which helps to prevent tilting due to cable drag when used in desktop applications. The DA1226AT uses an internal 90-140/200-240V switchable power supply. It may be rack-mounted using optional hardware.

Please attach the Interface on the rack or table using the optional hardware. Step 2. 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 the FUSE DIP 180 degrees, repositioning it in the clip so that the voltage is visible through the window. Please reinsert the fuse box, and push it in until the side clips of the fuse box click and lock securely into place. Step 3. Then connect the appropriate power cord for your country into the power input socket of the DA1226AT gently, but firmly. The power indicator light on the front panel of the DA1226AT should turn on. Step 4. Connect the video output of the source of the (computer or other high-resolution source) to input of the DA1226AT using a high quality of coaxial-type cables. If the source offers a VGA-type 15 pin HD connector, use a HD 15 to 5-BNC made for the MS8102CA or the MS8112CA. NOTE: 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. Step 5. Connect the output channels of the amplifier to the display devices (monitors and/or projectors.) using a good quality of coaxial cables. Step 6. Confirm picture quality on all displays. If you are not receiving a signal, make sure that the display is compatible with the resolution of the computer graphics card. If the picture quality is less than perfect, check to make sure that all of your connections are solid and that you are using a high quality cable. CONGRATULATIONS! YOU ARE DONE. If you experience any problems, please call 1-800-258-4623 or 1-714-990-2300 for international calls. 5 DISTRIBUTION AMPLIFIERS OPERATION 7 The DA1226AT will operate successfully as long as cables are attached correctly and other technical specifications are followed. There are no other adjustments necessary to operate the unit.
