Connections

Notes on connections

Read the instruction manual for each system component carefully before connecting it.

Turn off the power supply for all components before making any connections.

If the cables necessary for connecting a component to the system are not included with the component or available as an option, you may need to fashion a cable to suit the component concerned.

If there is a lot of jitter in the video signal which is input from the video source, the picture on the screen may flicker. In such cases, it will be necessary to connect a TBC (time base corrector).

B Refer to the list on page 56 for details on compatible signals which can be

input to the projector.

Only one audio system circuit is available for the AUDIO IN L-R jacks, so if you wish to change the audio input source, you will need to remove and insert the appropriate plugs.
