Installation
The following examples illustrate the conguration options for the distribution
amplier, when used with a HD component video source (YPbPr), HD RGBHV video
source, or composite video source.
Prior to installation, please situate the distributor near the video signal sources, as well
as an available power outlet, in order to minimize cabling requirement.
ST123HDA used with HD component video source (YPbPr)
