Inputs available (two kinds):
S-Video (super video) and Video (compos-
ite), plus audio left and right.

RF coaxial.
This is for antenna or cable RF input.

INPUT-AV 1/Component Video (CVI) Jacks
Signals accepted: NTSC (480i).
Inputs available (three types): Y Pb Pr (com-
ponent video), S-Video (super video), or Video
(composite), plus audio left and right.
Only one of the types of video inputs should be
used at a time. For either an S-Video or Video
connection, select the AV1 source in the on-
screen display. For a Y Pb Pr connection, select
CVI. For sound, connections must be made to
the INPUT-AV1 audio inputs.

INPUT-AV 2 Jacks
Signals accepted: NTSC (480i).
Inputs available (two types): S-Video (super
video) or Video (composite), plus audio left and
right.
Only one of the types of video inputs should be
used at a time. For either an S-Video or Video
connection, select the AV2 source in the on-
screen display. For sound, connections must be
made to the INPUT-AV 2 audio inputs.
4 HD INPUT-AV 3 Jacks
Signals accepted: 480p and 1080i, plus audio
left and right.
Inputs available (two types): Y Pb Pr (compo-
nent video) or RGB+HV sync, plus audio.
For sound, connections must be made to the
HD INPUT-AV 3 audio inputs.
5
HD INPUT-AV 4 Jacks
Signals accepted: Digital only (TMDS
[Transition Minimized Differential Signaling]
encoded, uncompressed); DVI 480p and 1080i,
plus audio left and right.
Inputs available: DVI TMDS, plus audio.
For sound, connections must be made to the
HD INPUT-AV 4 audio inputs.
6
OUTPUT Jacks
Provide video and left/right audio output signals
from the input source currently being viewed on
screen, except for HD INPUT-AV 3 or AV 4.
When HD INPUT-AV 3 or AV 4 is used, only
the audio is available through the OUTPUT
audio L/R jacks. The OUTPUT audio is at a
fixed volume level; changing the TV volume
does not affect them. Adjust the volume at your
external home cinema system.

CENTER CHANNEL AMP INPUT Click-fit
Terminals
Provides speaker-wire input terminals for con-
nection of an external home-cinema surround-
sound system amplifier. For this use, set the
switch to “EXT,” and the TV speakers become
the center speakers for the home-cinema sur-
round-sound system.
NOTE: If no audio is heard from the set, check
to make sure the Center Channel Amp switch is
in the INT position. This switch should be in the
EXT position only when an external center
channel input is connected to the Click-fit
Terminals.

Why So Many Types of Inputs?
As better-quality signals have become available, new inputs have been designed into
accessory devices (VCRs, DVD players, cable boxes, etc.) and TVs to carry them. The
other inputs have been left in place to work with the installed base of older equipment.
Here is a summary of the quality of signal offered by the different types of inputs:
Basic: ANTENNA IN 75
Ω
. May provide the only way to connect an antenna and some
older cable boxes and VCRs.
Good: VIDEO (Composite) Input. A small step up in quality from the ANTENNA IN
75
Ω
input. Most cable boxes, VCRs, and DVD players have this type of connection.
Better: S-VIDEO (Super Video) Input. Separates the signal into color and brightness,
improving image quality. Used with DVD players, digital cable boxes, satellite receivers,
and some camcorders.
Best: Y Pb Pr (Component Video) Input. Carry potentially the best-quality signals.
The video signal is split into three signals, two color and one brightness. Used primarily
with DVD players.
Color Coding Used on
Jacks and Plugs to simpli-
fy connections:
Yellow: VIDEO
(Composite Video)
Green, Blue, Red: Y Pb Pr
(Component Video)
Red: Right AUDIO
White: Left AUDIO.
