1.0 Matrix System Overview
1.0.1 VAX Matrix System
The VAX Matrix switcher is a high performance switching equipment for 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 VAX 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 VAX-2088 model. Refer to VAX-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 VGA female terminals. The audio input/output jacks are formed by the 4th and 8th row 5-phase 3.8mm connection terminals. The VAX-2088 video signal input/output terminal channels are numbered from lower to upper and from left to right as NO.1 to NO.8 channels (in two rows). The video port is the video signal terminal. The audo signal input/output terminal channels are numbered from left to right as NO.1 to NO.8. Refer to the drawing on the housing for port terminals of different models.
Different models of the VAX 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 Video Connecting Cable
Data processed by the display card will ultimately be output to the display, and the display output connector bridges together the computer and the display. It is responsible to output corresponding graphics signals to the display. Due to design and manufacturing, the CRT monitor can only receive analog signals, thereby the display card must also be able to input analog signals. The VGA (Video Graphics Array) connector, also called D-Sub conector, is the connector of graphics card for output of analog signals. Although the LCD display can directly receive digital signals, many low-end products still use VGA connectors for connection to the
8
VGA card. The VGA connector is a D-sub connector with 15 pins in 3 rows (each row has 5 pins).
Presently, most computers connect with external displays via analog VGA connectors. The computer internally generates digital graphics data to be converted by the graphics card digital/analog converter into the R, G, and B process color signals, and coutour and gamut synchronous signals which are transmitted to the display via the cable. Regarding analog display equipment such as the analog CRT display, the signals are being sent directly to the corresponding processor circuit and drive the controlling Cathode Ray Tube into graphics display. Digital displays such as LCD and DLP are usually equipped with A/D (Analog/Digital) converters to convert analog signals into digital signals. Unavoidably, some losses to graphics happen after two times of conversion from analog to digital and vice versa. It’s understandable to use VGA connectors in CRT monitors, but to use it in LCD displays the quality of graphics display is likely to degrade in the process of conversion.
Different models of the VAX 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.
The RCA connecting terminal----audio/video port: The 4-hole RCA Jack is a conventional audio connector. Its installation hole measures 14x18mm.
The VAX Matrix supports various AV signal sources.
