Connecting the TX-NR901
—Continued
• Read the manuals supplied with your AV components.
• Don’t connect the power cord until you’ve completed
all audio and video connections.
Optical Digital Inputs
The TX-NR901’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.
RCA/phono AV Connection Color Coding
RCA/phono AV connections are usually color coded:
red, white, and yellow. Use red plugs to connect right-
channel audio inputs and outputs (typically labeled “R”).
Use white plugs to connect left-channel audio inputs and
outputs (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 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 the most common video con-
nection format and is found on virtually all TVs,
VCRs, and video equipment.
Audio
Cable Socket Description
Optical digital
audio cable

mon connection format for analog audio, and can be
found on virtually all AV components.
