The AC/DC switch is used to select AC or DC coupling of video signal through a distribution amplifier. The TERM switch is used to terminate or unterminate RED, GREEN, & BLUE inputs with 75 Ohms. The GAIN switch is used to set gain to 1 or 1.3. The EQLZ switch is used to compensate for longer cable runs. APPLICATION DIAGRAM 5 4.3 SYNC CONTROL SWITCHES The DA1322AT has separate Sync control switches: TERM H, C SYNC, TERM V, and SYNC G. The TERM H switch is used to terminate or unterminate horizontal sync input with 75 Ohms. The TERM V switch is used to terminate or unterminate vertical sync input with 75 Ohms. The C Sync switch is used with composite sync. The Sync G switch is used with sync on green. 4.4 BANDWIDTH Offering a minimum video bandwidth of 350 MHz and typical bandwidth close of 500 MHz, the DA1322AT allows even very high resolution video signals to pass without degrading the image quality. 4.5 POWER Designed with a universal power input connector, the DA1322AT offers a built-in linear power supply with continuous operation at 95V to 240V. 5 DISTRBUTION AMPLIFIERS INSTALLATION 6 OPERATION 7 Step 1. Connect the power cord to the unit and plug it into the power outlet. The power indicator LED on the back panel will light. This indicates that the unit is operational. Step 2. Connect the video output of the source (computer or other high-resolution source) to the input of the DA1322AT using a high quality coaxial-type cable. If the source offers a VGA-type 15-pin HD connector, for instance, Altinex part # MS8102CA (6' – 15-pin HD male to 5 BNC male) may be used. The active signal indicator on the back panel will light. This indicates that you have an input signal on the input of the distribution amplifier. Note: You may have to use an interface with your computer to provide for the appropriate signal format type and to provide for the use of a local monitor if called for. Step 3. Next, connect the output channels of the amplifier to the display devices (i.e. monitors and /or projectors). Step 4. Verify that the picture quality on all displays is good. 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 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. The settings of the DA1322AT Distribution Amplifier can be adjusted using the Channel dip switches and Sync control switches as described in Section no. 4. There are no other adjustments necessary to operate the unit. The DA1322AT will operate successfully as long as cables are attached properly and other specifications are followed.

The DA1322AT offers individual channel adjustment for gain and peaking, allowing specific control over the outputs for different lengths of cable. 2 Are the outputs of the DA1322AT buffered? Yes, the DA1322AT offers two individually buffered outputs. 3 What is meant by buffered output? 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 4 If the input of the DA1322AT provides an RGBHV format signal what is available on the output? The DA1322AT offers sync combining and ...
