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

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 RCAJack 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 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 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:

YX Matrix Switching System—User Manual
10
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 RCAJAYK 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 RCAconnector 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 RCAsignal cable.
NOTE: The RCAconnectors 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. TheAV 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 installation of application software.

5.0.3 Remote Control Methods and Settings
The YX matrix provides standard RS-232 and RS-485 serial communication ports. Aside
from using the front panel keys for switching operation, you are also permitted to use the RS-232
and RS-485 serial communication ports for remote operation. It also supports RS-485 serial
control.
