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 projec ts, 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.

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 audio 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.

10.0 Common Problems and Solutions
1. What to do if the SX matrix front panel keys switching not responsive?
Answer: The SX matrix front panel keys employ scanning testing and require longer response
time. Press the keys for 2 seconds and then release. This way, key switching will be
responsive in operation.
2. What to do if matrix does not display or color display is abnormal after hot plug?
Answer: Switching of the matrix system goes through the IC chips. If the voltage difference
between the input signal equipment and the matrix equipment is too large, hot plug
could easily cause damage to the IC chips. Please turn off power to the system before
plugging or unplugging.
3. What to do if ghosting happens when S-Video signals output to display?
Answer: Ghosting is often caused either by the projector, inferior cable quality or long
transmission distance. You are advised to adjust the projector or replace with better
quality cable.
4. What to do if loss of color reproduction happens or no video signal output?
Answer: Please check if connectors at both ends of the S-Video signal cable are correctly
connected.
5. What to do if the serial port (usually refer to the computer serial port) fails to control the SX
matrix?
Answer: Check that the communication port set by the control software is correctly connected to
the corresponding serial port of the equipment. Also, check if the computer
communication port is in good order.
6. What to do if the corresponding graphics fail to output during SX matrix switching?
Answer: (1) Check if there is signal on the input end. If there is no input signal, it could be that
the input connection cable is broken or the connector gets loosen. You are advised to
replace the connection cable.
(2) Check if there is signal on the output end. If there is no output signal, it could be that
the cable is broken or the connector gets loosen. You are advised to replace the
connection cable.

(3) Check if the output port number is the same as the controlled port number.
(4) If none of the above circumstances happen, it could be internal failure of the product
itself. You must send for repair by qualified technical engineers.
7. What to do if the power LED is not on, LCD has no display and no response in operation?
Answer: Check if the equipment power input is in good contact.
8. What to do if you sensed power leakage during plugging or unplugging of the audio/video
ports?
Answer: It could be that the equipment power is not properly grounded. You must properly
ground your equipment, otherwise product life can easily be shortened.
9. What to do if the LCD displays normally and the communication port has return code but no
graphics output or audio output?
Answer: (1) It could be that the audio/video connectors got loosen. Simply replace the
connectors.
(2) It could be the connection cable short-circuited. Simply replace the cable.
(3) It could be the connection cable is broken. Simply replace the cable.
10. What to do if the SX matrix panel keys and communication ports are out of order?
Answer: Check if the equipment power input is in good contact and the computer
communication ports are in good order. If yes, it could be some internal failure of the
product, please send for repair by qualified technical engineer .
11. What to do if operation and function failure occurred?
Answer: Check if the equipment and the matrix system are in proper connection. If the problem
persists, send the product to the maintenance center for repair.
NOTE:
Do not replace the power cord yourself. If the power cord is damaged, ask your distributor to
send qualified technician to replace it for you.
