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 installation of application software.
