About Audio and Video Connections
• Before making any AV connections, read the
manuals supplied with your other AV compo-
nents.
• Don’t connect the power cord until you’ve
completed and double-checked all AV connec-
tions.
Optical Digital Jack
The NVS-7.7’s optical digital jack has a shutter-
type cover that opens when an optical plug is
inserted and closes when it’s removed. Push the
plug in all the way.
RCA Audio Connections
RCA-type audio connections are usually color-
coded red and white. Use red plugs to connect
right-channel audio inputs and outputs (typi-
cally labeled “R”). Use white plugs to connect
left-channel audio inputs and outputs (typically
labeled “L”).
• Push plugs in all the way to
make good connections
(loose connections can cause
noise or malfunctions).
• To prevent interference, keep
audio and video cables away
from power cords and speaker cables.
AV Cables and Jacks
Caution:
To prevent shutter damage, hold
the optical plug straight when inserting and
removing.

Description
DVI cable
This offers the best picture quality and delivers the
digital video signal directly to the display.
VGA cable
This is a high-quality analog video connection and
is commonly used to connect computer displays.
Component
video cable
Component video separates the luminance (Y) and
color difference signals (P
R
, P
B
), providing better
picture quality than S-Video. (Some TV manufac-
turers label their component video jacks slightly
differently.)
S-Video/com-
posite cable
S-Video separates the luminance and color signals
for a better picture. We recommend that you use
the S-Video plug.
