1.0 Matrix System Overview
1.0.1 SX Matrix System
The SX Matrix switcher is a high performance switching equipment for S-Video and audio
frequency. It is used for input/output cross switching of multi-video and audio frequency signals.
It provides separate video and audio jacks for separate transmission of each video frequency
component signal and audio frequency signal, thereby minimizing signal attenuation and
ensuring high definition and high fidelity graphics and audio signal output.
The SX Matrix is used mainly in TV broadcasting projects, multi-media conference halls,
large display projects, TV teaching and command control centers. It boasts features of power
interruption protection during power surge, LCD display and synchronous and separate
audio/visual switching functions. Its RS-232 communication port enables convenient
communication with remote control equipment. This manual describes using of the SX-2088
model. Refer to SX-2088 User Manual for using of other models of matrix systems.

5.0.1 Input/Output Jacks
Referring to the different models, the video signal input/output jacks are formed by the 4th
row and 8th row S-Video and RCA female terminals. Lining from the top to the bottom are
respectively video and audio signal terminals. The video signal terminals are S-Video, the audio
signal terminals are red (right audio channel) and white (left audio channel). Channels of the
output terminals are numbered from left to right from 1 to 8. Refer to the drawing on the housing
for port terminals of different models.
Different models of the SX matrix system provides a different number of input/output jacks
for users to connect to different audio/visual equipment including CD/DVD players, graphics
workstations, and number displays. The output terminals can be connected to projectors, video
recorders, displays and multiplexers and so on.
5.0.1.1 Audio Connecting Cable
Different models of the SX matrix system provides a different number of input/output jacks
for users to connect to different audio/visual equipment including CD/DVD players, graphics
workstations, and number displays. The output terminals can be connected to projectors, video
recorders, displays and multiplexers and so on.
S-Video video connector is a standard (Y/C）Min-din 4PIN connector.
RCA audio connector is a pair of (R/L) female RCA connectors.
The SX Matrix supports various AV signal sources.

SX Matrix Switching System—User Manual
AV Connector—standard AV Input （S-Video/RCA）Connector:
Type: Audio connectors are in pairs (left/right channels) (white/red) and video connector
(S-Video)
SX matrix RCA and S-Video connection, see Figure 5-2 below:
Figure 5-2 RCA and S-Video Connection
Generally, the RCA audio terminals are indicated in pairs by different colors: the right audio
channel uses red color (or use the letter “R” to indicate “Right”); the left a udio channel is usually
black or white. Generally speaking, the RCA stereo cable is one cable to contain both left and
right audio channels.
Advantages: The AV connector realizes separate transmission of audio and video frequencies,
thereby averting decline of graphics quality due to audio/video interference. Presently, almost
every TV set provides this connector for video input.
Connection method: Use the RCA-type socket for connection. Connect the video S-Video and
audio RCA (R/L) connectors of the output terminal of the signal source equipment respectively
to the same SX matrix input channel and connect the SX output via dedicated video S-Video and
audio RCA (R/L) signal lines to the video S-Video and audio RCA (R/L) input connectors of the
output equipment.
NOTE: The RCA (R/L) connectors at both ends of the signal lines must correspond to each
other, otherwise signals on the R/L audio channels would be reversed.
Audio Connecting Cable:
The “Audio Input” and “Audio Output”jacks of the SX matrix can be used to connect a video
recorder and a multiplexer respectively.
The audio cable branches into left and right audio channels. The red RCA represents the right
audio channel and the white RCA represents the left audio channel.
