Connections & Setup
24 Chapter 1
WIRED REMOTE CONTROL (IR) (available on some models) This jack is for
connecting a wired remote control system, which is primarily for professional installers. If
you’re using the remote that was included with your TV, don’t plug anything into this jack
or the TV won’t respond to the remote.
DIGITAL AUDIO OUTPUT (OPTICAL) Use a digital optical cable (or SPDIF
cable) to connect your TV to a compatible Dolby Digital or PCM receiver or decoder.
Dolby Digital Technology offers theatre-quality sound (six audio channels). If you own a
receiver that uses an optical cable input, you can use an optical cable to connect the TV to
that receiver for the best sound quality. Go to the Digital Audio Out screen in the Audio
menu to select Auto Select or PCM as the output for this jack.
Note: This TV’s optical digital output jack fully complies with the international
standard governing this type of jack (IEC958), and is designed for connection to
a Dolby Digital (AC-3
® or PCM) receiver or decoder. Older equipment, some of
which is not fully compliant with IEC958, may not be compatible with the Dolby
Digital bitstream. Such a connection using anything other than a Dolby Digital
(AC-3 or PCM) receiver or decoder could create a high noise level, causing damage to
headphones or speakers.
ANTENNA INPUT Used to connect a coaxial cable to receive the signal from an
off-air antenna.
CABLE INPUT Used to connect a coaxial cable to receive the signal from cable or a
cable box.
