ABOUT YOUR DISTRIBUTION AMPLIFIER 2

The DA1913GL is a 1-in 2-out RGBS distribution amplifier designed to allow the connection of a single computer or interface source to one or two monitors or projectors. The DA1913GL also provides ground loop isolation through the use of differential inputs with a common mode rejection of +/-2.0V, making it perfect for applications with challenging power supply scenarios. A ground loop is a type of electromagnetic interference often caused by small, but significant differences in ground voltage between two or more different power sources when equipment using the different power sources is connected by means of video/audio inputs and outputs. A ground loop may also be caused when high current equipment (such as a lighting or air conditioning system) is fed from the same power source as the display equipment.

Though primarily designed to pass an RGBS signal format through 4-BNC connectors for each input/output, the DA1913GL can also pass RGsB, Component Video (Y, R-Y, B-Y), S-Video (Y/C), and Composite Video by using the appropriate channels. The DA1913GL can pass C-Video and S-Video simultaneously by using Red for C-Video and Green/Blue for Chroma/Luma respectively. The DA1913GL is typically used for permanent installation and is supplied with a 12-inch power cable with bare leads requiring the connection of 9V 500mA DC power. The DA1913GL does not come with a power adapter; it has to be wired to a power source using the bare leads.

The DA1913GL is extremely compact, allowing it to fit nicely into tight spots. It may also be mounted to almost any surface using optional ”L” type mini brackets.

The DA1913GL Distribution Amplifier is a state-of- the-art product with a video bandwidth of 350 MHz, enabling it to remain transparent to the video signal passing through it. Each output is individually buffered and is not affected by other output loading.

The common mode range of the DA1913GL Distribution Amplifier is +/-2 Volts with a video signal of 1 Volt p-p. In most cases, a ground loop voltage will not exceed 200-300mv, so this range is more than enough to handle even the most severe ground loop problems.
