Input/Output Jacks
Dependent on the matrix model installed, the video signal input/output jacks are arranged in
either 4 or 8 columns of RCA female connectors. The connector rows from top to bottom are:
Y video (green), Pb/Cb video (blue), Pr/Cr video (red), right audio signal (red), and left audio
signal (white). The input and output jack channels are numbered from left to right as 1 to 8
(or 1 to 4). Refer to the drawing above for other types of connectors. The model numbers of the
matrix systems describe the number of input/output connectors. Example: Model SW404HD
has 4 input sets and 4 output sets.
Connecting Audio/Video Cable
The matrix supports various AV video signal sources. Users can connect inputs and outputs to
different audio/visual equipment such as: CD/DVD players, graphics workstations and number
displays, projectors, video recorders, displays, multiplexers, and etc.
Audio/Video Ports
The RCA Jack used is a standardized audio/video connector. It uses coaxial signal connections
in the center conductor and the outer ring for grounding. It will transmit digital audio signals and
video signals.
Video I/O (3-RCA) Connectors
The Y/Pb/Pr connector is a high definition digital TV
connector (color contour Y/Pb/Pr) capable of
connecting with high definition digital set-top box,
satellite receiver and various high definition
monitors and TV equipment. There are separate
connectors for the Y, Pb, and Pr signals.
