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.

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 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.
