6IR IN: This input is connected to the output of an IR (infrared) repeater (Xantech or similar), or the IR output of another component to allow control of the L53 from a remote location. Ask your dealer or custom installer for further details.

7OPTICAL & COAXIAL IN: Connect to the coaxial/optical S/PDIF- format digital output of sources such as VCRs, HDTV or satellite tuners, or other components; connect IN OPTICAL/COAXIAL to an S/PDIF-format digital output. We recommend your source material be set to PCM 2-channel format for these digital inputs.

NOTE

During power-on from standby, there may be a momentary mute of audio if CD/DVD-media is present in the L53's DVD tray, and either Coaxial or Optical inputs are in use. This feature is normal operation that allows the L53 to load the media's tables of contents and title menus into memory. To avoid this momentary mute of audio, remove the media from the L53's DVD tray before switching to standby.

8 OPTICAL OUT: Connect the OUT OPTICAL port to the corresponding S/PDIF digital input of a recording component such as a CD recorder, DAT deck, or computer soundcard.

9COMPONENT VIDEO OUT: Connect the L53’s “COMPONENT VIDEO OUT” to the component-video input of a compatible video monitor/TV. Be sure to observe consistency in connecting the Y/Cr/Cb jacks (some source and TV components label these Y/Pb/Pr) to the corresponding sources/inputs; do not rely purely on the colour coding of the jacks, which may not always be consistent among brands. The routing of the component-video output is fixed: “COMPONENT VIDEO OUT” jack will only display the internal DVD video signals.

NOTE

The L53’s component-video output is a fully wide-band output, compatible with all HDTV formats. The L53 will display its on- screen menus on its component-video output.
