1.0 Matrix System Overview
1.0.1 CX Matrix System
The CX 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 CX 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 CX-2088
model. Refer to CX-2088 User Manual for using of other models of matrix systems.

5.0.1 Input/Output Ports
Referring to the different models, the video signal input/output jacks are formed by the 4th
row and 8th row RCA female terminals. Lining from the top to the bottom are respectively video
and audio signal terminals. The video signal terminals are yellow in color while 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 CX 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.

Different models of the CX 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.

CX Matrix Switching System—User Manual
The CX Matrix supports various AV signal sources.
AV Connector—standard AV Input RCA）Connector:
Type: Audio connectors are in pairs (left/right channels) (white/red) and video connector
(yellow)
CX matrix RCA jack connection, see Figure 6-2 below:
Figure 6-2 BNC 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 4-hole RCA Jack (commonly referred to as the sprayer head
which measures 14x18mm) for connection to input/output equipment. Connect the video, audio
RCA connectors of the signal source equipment output terminal to the same RCA connector of
the CX matrix input. Then, connect the RCA connectors of the CX matrix output, via a dedicated
RCA signal cable, to the RCA input jack of the output equipment.
NOTE: Correctly connect the two ends of the signal cable to the RCA connector, or else
discoloration happens or even no signal output.
Audio Connecting Cable:
The “Audio Input” and “Audio Output”jacks of the CX 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.
