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.
Note: A power adapter for the DA1913GL must be
ordered separately, if required. In the United
States, the PS5502US Power Adapter can be
used, though the connector must be cut off to allow
interconnection.
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.
