Answer
A Distribution Amplifier is a device that allows you to connect a single video source to multiple display devices, such as monitors or projectors used in presentation applications.
In some cases, you need a

By setting sync polarity switch to (+) the signal is processed as unchanged and the sync polarity of the output signal is matched with the sync polarity of the unit. By setting the sync polarity to
The SYNC LEVEL switch has two positions 2V and 4V. Most often a 4V Sync Level is used. This should be considered as the default setting. The 2V setting allows compatibility with some older equipment that would be overdriven if stronger signal is used.

TROUBLESHOOTING GUIDE | 10 |
We have carefully tested and have found no problems in the supplied DA1206RM unit; however, we would like to offer the following suggestions:
∙Please make sure that the input amplitude levels are as follows.
1.Analog signal is less than 1.5V.
2.Sync signal is less is than 0.3V.
∙Please check the settings of the Sync level, the Video level, and the Sync Polarity Switches.
∙Please make sure that the proper quality of cables is used. We recommend Altinex made cables for best results.
∙If a problem arises after continuous usage at higher voltage, higher temperature, higher humidity, or at other extreme environmental conditions, please correct the problem.
