1.0 Matrix System Overview

1.0.1 YX Matrix System

The YX Matrix switcher is a high performance switching equipment for audio/video frequencies.
It is used for multiple input/output cross

switching of audio/video signals. It provides independent YPbPr component and audio
input/output terminals. Each YPbPr component signal and audio signal is transmitted
separately and switched separately, thereby minimizing signal attenuation and ensuring high
definition graphics and high fidelity signal output.

The YX Series 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/video switching functions. Its RS-232 and RS-485 communication ports enable convenient
communication with remote control equipment. This manual describes using of the YX-3088
model. Refer to the YX-3088 User Manual for using of other models of matrix systems.

5.0.1 Input/Output Jacks

Referring to the different matrix models, the video signal input/output jacks are formed by
the 4th and 8th rows RCA female connectors. The connectors from top to bottom are: Y, Pb/Cb,
Pr/Cr, Audio Signal Jack. The Y signal jack is green, the Pb/Cb signal jacks are blue, the Pr/Cr
signal jacks are red, and the upper row audio jacks are red (right audio channel) and the lower
row audio jacks are white (left audio channel). The output jack channels are numbered from left

YX Matrix Switching System—User Manual

to right as NO.1 to NO.8 (in five rows). Refer to the drawing on the housing for other types of
connectors.

Different models of YX matrix systems provide a different number of input/output
connectors where users can connect to different audio/video equipment including CD/DVD
players, graphics workstations, and number display. The output connectors can be connected to
projectors, video recorders, displays and multiplexers.

5.0.1.1 Audio/Video Connecting Cable

Different models of the YX 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 YX matrix supports various AV video signal
sources.

The RCA connecting terminal----audio/video port: The 4-hole RCA Jack is a conventional
audio connector. Its installation hole measures 14x18mm.

YPbPr Connector—Standard Video Input (3-RCA) Connector:

Type: Video connectors are in pairs (Y, Pb, Pr) (Green Y, Blue Pb, Red Pr)
For YX matrix YPbPr RCA jack connection, see Figure 6-2 below:

Figure 6-2 YPbPr -RCA Connecting Cables
RCA, an abbreviation for lotus socket, is a DVD component (YpbPr) socket.
The YpbPr connector is a high definition digital TV connector (color contour YpbPr)

capable of connecting with high definition digital set-top box, satellite receiver and various high
definition monitors and TV equipment.

Color difference output (YPbPr) connector separates the modulated Y, PB and PR signals. It

separates the colorimetry C signal into blue b-Y color difference and red r-Y color difference and
uses 3 cables for separate transmission to improve display resolution. This way, it ensures the
largest bandwidth of colorimetry and averts interference to the signals b ecause the signals are
transmitted by 3 separate cables and each cable is being properly sleeved.

The Audio Connecting Cable:

Type: The audio connecting cables are in pair for left and right channels (R for red and L

for left).

Connection of the RCA connector of the YX matrix audio is as shown in Figure 6-3

below:

9

YX Matrix Switching System—User Manual

Figure 6-3 AUDIO RCA Connecting Cables

The RCA connector uses coaxial signal transmission with the axial for signal transmission

and the outer ring for grounding. It can be used to transmit digital audio signals and modulated
video signals. Generally, the RCA audio connectors are in pairs separately indicated by red for
the right audio channel (R for right) and black or white for the left audio channel (L for left). The
RCA stereo cable is in one set for both left and right audio channels with each channel in one
cable.

The YX matrix “Audio Inputs” and “Audio Outputs” can be separately connected to the

audio signal connector of the video recorder and a multiplexer.

Connection Method: Use the RCA (often referred to as the lotus socket) connector for

connection. You are recommended to use the 14 x 18mm 4-hole RCA JAYK connector for
connection to input and output equipment. Connect the RCA video and audio connectors of the
signal source equipment output terminal to the same channel RCA connector of the YX matrix
input terminal, and also connect the RCA connectors of the YX matrix output terminal to the
RCA input connectors of the output equipment via a dedicated RCA signal cable.

NOTE: The RCA connectors at both ends of the various signal cables must correspond to

each other, otherwise loss of color reproduction or even no signal output could happen.

Advantage: The AV connectors have realized separate audio and video transmission,

thereby averted mixed audio/video interference to degrade graphics quality. The AV connectors
have now been extensively used in TV equipment.

5.0.2 YX Matrix and Control Computer Connection

Use the RS-232 connecting cable to connect the computer serial port (COM1 or COM2) to

the RS-232 communication port of the YX matrix host. The computer can then be used to control
the YX matrix after installa tion of application software.

10.0 Common Problems and Solutions

1. What to do if the YX matrix front panel keys switching not responsive?
Answer: The YX 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 YPbPr 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 YPbPr signal cable are correctly

connected.

5. What to do if the serial port (usually refer to the computer serial port) fails to control the YX
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 YX 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 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 YX 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.
