ABOUT YOUR DA1907SX
2
The  DA1907SX (Ditto-Amp) is a high-resolution, 
1-in 2-out distribution amplifier designed to allow 
the connection of a single VGA/SVGA/XGA/UXGA 
source to up to two scan-rate compatible displays. 
A minimum video bandwidth of 400 MHz allows 
very high-resolution video signals to pass without 
degradation to the image quality. The Local Monitor 
Output of the DA1907SX is pre-compensated for 
up to 12 feet of high-resolution coaxial-type VGA 
cable. The Main Output of the DA1907SX is pre-
compensated for up to 250 feet with high-resolution 
coaxial-type VGA cable.
Being compact and easy to use, the DA1907SX is 
perfect for audio/visual installations, where a single 
computer needs to be connected to a projector (or 
presentation monitor) and a local monitor 
simultaneously. The DA1907SX has female 15-pin 
HD (VGA type) connectors on all input and output 
connectors so it can be used with readily available
standard VGA type cables. If desired, the input 
and/or output of the DA1907SX can be easily 
adapted to 5 BNC connectors through Altinex
adapter cables.
The  DA1907SX is compatible with RGsB, RGBS, 
or RGBHV signal types and with the proper cable 
the DA1907SX can be used with MAC, SUN or SGI 
platform computers.
