PACKAGE CONTENTS
This package contains:
One ST-VDABNC-2 video distribution amplifier.
One 12VDC 500mA power supply.
One installation manual.
PRODUCT DESCRIPTION
The ST-VDABNC-2 is a single input, two output video distribution amplifier and splitter with a
single potentiometer to synchronize gain (brightness), equalization and sharpness. The unit’s low
pass filtering, broadcast distribution quality and ground loop isolation circuits have been
professionally designed for CCTV video signal amplification, transmission and video distribution
applications requiring high performance video signal restoration over coaxial cable.
