Connecting AV Components
• Read the manuals supplied with your AV components.
• Don’t connect the power cord until you’ve completed
and double-checked all audio and video connections.
Optical Digital Inputs
The TX-L55’s optical digital inputs have shutter-type
covers that open when an optical plug is inserted and
close when it’s removed. Push plugs in all the way.
Caution: To prevent shutter damage, hold the optical
plug straight when inserting and removing.
RCA AV Connection Color Coding
RCA-type AV connections are usually color coded: red,
white, and yellow. Use red plugs to connect right-chan-
nel audio inputs and outputs (typically labeled “R”). Use
white plugs to connect left-channel audio inputs and out-
puts (typically labeled “L”). And use yellow plugs to
connect composite video inputs and outputs.
• Push plugs in all the way to make
good connections (loose connec-
tions can cause noise or malfunc-
tions).
• To prevent interference, keep
audio and video cables away from
power cords and speaker cables.

AV Cables & Sockets
■
Video
Cable Socket Description
Component
video cable
Component video separates the luminance (Y) and
color difference signals (P
R , P B ), providing the best
picture quality. (Some TV manufacturers label their
component video sockets slightly differently.)
S-Video cable
S-Video separates the luminance and color signals
and provides better picture quality than composite
video.
Composite
video cable
Composite video is commonly used on TVs, VCRs,
and other video equipment. Use only dedicated
composite video cables.

Audio
Cable Socket Description
Optical digital
audio cable
Offers the best sound quality and allows you to
enjoy surround sound (e.g., Dolby Digital, DTS).
The audio quality is the same as for coaxial.
Coaxial digital
audio cable
Offers the best sound quality and allows you to
enjoy surround sound (e.g., Dolby Digital, DTS).
The audio quality is the same as for optical.
Analog audio
cable (RCA)
This cable carries analog audio. It’s the most com-
mon connection format for analog audio, and can be
found on virtually all AV components.
Multichannel
analog audio
cable (RCA)
This cable carries multichannel analog audio and
it’s typically used to connect DVD players with
individual 5.1-channel analog audio outputs. Sev-
eral standard analog audio cables can be used
instead of a multichannel cable.
