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.
