• Before making any AV connections, read the manuals
supplied with your other AV components.
• Don’t connect the power cord until you’ve completed
and double-checked all AV connections.
Optical Digital Jacks
The AV receiver’s optical digital jacks 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.
AV Connection Color Coding
RCA-type 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
connections can cause noise or
malfunctions).
• To prevent interference, keep
audio and video cables away from
power cords and speaker cables.
