3. System Connection
3.1. Usage Precautions
1) System should be installed in a clean environment and has a prop temperature and
humidity.
2) All of the power switches, plugs, sockets and power cords should be insulated and
safe.
3) All devices should be connected before power on.
3.2. System Diagram
3.3. Connection Procedures
Step1.Connect source devices (e.g. PC, DVD) to video input ports with corresponding
cables. For example, connect VGA INPUTS ports and the VGA ports of source
devices via VGA cable.
Step2. Connect the corresponding audio source to the corresponding AUDIO INPUT
port of SCA121DTN with audio cable separately. C-VIDEO1 shares the same
audio input port with S-VIDEO3; Pr-Pb-Y shares the same audio input port with
C-VIDEO4, you can select either side as audio input port.
