Connection to the
external equipments
• If your VCR (or other external devices) has an S-Video terminal, S-Video connection is recommended because S-Video
signal has the better quality than VIDEO signal of A/V IN..
• If your external device has Component terminal and S-Video terminal both, Component connection is recommended.
Component video signal is superior to S-Video signal.
• The sound or image signals coming into COMPONENT or S-VIDEO will not be transmitted to MONITOR OUT terminals.
• S-VIDEO and VIDEO in AV IN share the same jack with AUDIO input. Thus ,they can't be used at the same time.
• COMPONENT inputs accept only 480i video signal, so make the external equipment(DVD or DTV Set -Top Box) to
480i mode.
