FREQUENTLY ASKED QUESTIONS 9
No: Question Answer
1 What is the
maximum length
of cable that can
be used with the
DA1913GL ?
Compensation for cable
loss is automatically
made for a distance of
100 feet, though the
DA1913GL can drive
signals through longer
runs depending on the
source signal resolution
and cable quality.
2 Can I use the
DA1913GL
power supply to
power 2 units
simultaneously?
It is not recommended
since one power supply
is supplied with each
unit. Please consider
the
PS5581SM , a rack
mount power supply.
3 Are outputs 1 & 2
buffered?
The DA1913GL has two
individually buffered
outputs.
4 What is common
mode range of
the
DA1913GL
and why is it so
important?
The common mode
range of the
DA1913GL
Distribution Amplifier is
+/-2V with a video signal
of 1V 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.
5 How will the
DA1913GL
provide protection
from a ground
loop in the
system?
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
