PRECAUTIONS / SAFETY WARNINGS  
1
Please read this manual carefully before using your  
DA1913GL Distribution Amplifier. Keep this manual  
handy for future reference. These safety  
instructions are to ensure the long life of your  
DA1913GL and to prevent fire and shock hazard.  
Please read them carefully and heed all warnings.  
·
To turn off the main power, be sure to remove  
the cord from power outlet. The power outlet  
socket should be installed as near to the  
equipment as possible, and should be easily  
accessible.  
·
·
Do not pull power cord or any cable that is  
attached to the DA1913GL Distribution  
Amplifier.  
1.1 GENERAL  
·
Unauthorized personnel shall not open the unit  
since there are high-voltage components inside.  
If the DA1913GL Distribution Amplifier is not to  
be used for an extended period of time,  
disconnect the power cord from the power  
outlet.  
·
Qualified Altinex service personnel, or their  
authorized representatives must perform all  
service.  
1.2 SAFETY GUIDELINES FOR THE RACK-  
MOUNTING OF THE DA1913GL  
1.4 CLEANING  
·
Unplug the DA1913GL power cord before  
cleaning. Clean surfaces with a dry cloth. Never  
use strong detergents or solvents such as  
alcohol or thinner. Do not use a wet cloth or  
water to clean the unit.  
·
·
·
Maximum operating ambient temperature is 35  
(degrees C).  
Never restrict the air flow through the devices’  
fan or vents.  
1.5 FCC / CE NOTICE  
When installing equipment into a rack, distribute  
the units evenly. Otherwise, hazardous  
conditions may be created by an uneven weight  
distribution.  
·
This device complies with Part 15 of the FCC  
Rules. Operation is subject to the following two  
conditions: (1) This device may not cause  
harmful interference, and (2) this device must  
accept any interference received, including  
interference that may cause undesired  
operation.  
·
·
Connect the unit to a properly rated supply  
circuit.  
Reliable Earthing (Grounding) of Rack-Mounted  
Equipment should be maintained.  
·
This equipment has been tested and found to  
comply with the limits for a Class A digital  
device, pursuant to part 15 of the FCC Rules.  
These limits are designed to provide reasonable  
protection against harmful interference when the

steam can harm internal components.  
environment. This equipment generates, uses,  
and can radiate radio frequency energy and, if  
not installed and used in accordance with the  
instruction manual, may cause harmful  
interference to radio communications. Operation  
of this equipment in a residential area is likely to  
cause harmful interference in which case the  
user will be required to correct the interference  
at his own expense.  
·
·
Handle the DA1913GL Distribution Amplifier  
carefully. Dropping or jarring can damage  
internal components.  
Do not place heavy objects on top of the  
DA1913GL. If the DA1913GL is to be mounted,  
to a table or wall, use only Altinex made

DISTRIBUTION AMPLIFIERS  
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.  
·
Any changes or modifications to the unit not  
expressly approved by Altinex, Inc. could void  
the user’s authority to operate the equipment.  
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.  
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.

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.
