1.0 Matrix System Overview
1.0.1 YX Matrix System
The YX-1042 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-1042 Matrix is used mainly in TV broadcasting projects, multi-media conference
halls, large display projects, TV teaching and command control
centers.

4.0.1 Input/Output Jacks
The video signal input/output jacks of YX-1042 are formed by the 4th and 2th rows RCA
female connectors. The connectors from top to bottom are: Audio Signal Jack. Y, Pb/Cb,
Pr/Cr.The Y signal jack is green, the Pb/Cb signal jacks are blue, the Pr/Cr signal jacks are red
and the left row audio jacks are red (right audio channel) and the right row audio jacks are white
(left audio channel) and the digital optical module.
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.
4.0.2 Audio/Video Connecting Cable
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 set (Y, Pb, Pr) (Green Y, Blue Pb, Red Pr)
ForYXmatrixYPbPrRCAjack connection, see Figure 4-2 below:
Figure 4-2 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 because 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 set 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 4-3 below:

YX-1042 Matrix Switching System—User Manual
Figure 4-3 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-1042matrix “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-1042 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.

7.0 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?

YX-1042 Matrix Switching System—User Manual
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 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.
6. 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.
7. 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.
8. 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.
9. 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.
