correctly to the audio input jacks for that
component.
• Check that the cord(s) used for the
connection is (are) fully inserted into the
jacks on both the receiver and the
component.
There is no sound from one of the front
speakers.
• Connect a pair of headphones to the
PHONES jack to verify that sound is
output from the headphones. If only one
channel is output from the headphones, the
component may not be connected to the
receiver correctly. Check that all the cords
are fully inserted into the jacks on both the
receiver and the component. If both
channels are output from the headphones,
the front speaker may not be connected to
the receiver correctly. Check the
connection of the front speaker which is
not outputting any sound.
• Make sure you have connected to both the
L and R jacks of an analog component, and
not only to either the L or R jack. Use an
audio cord (not supplied). However, there
will be no sound from the center speaker
when a sound field (Pro Logic, etc.) is
selected. When the center speaker is not
connected, sound is output only from the
front left/right speakers.
There is no sound from analog 2
channel sources.
• Check to make sure the selected digital
audio input jack is not assigned to other
inputs in "Input Assign" in the Input
Option menu (page 109).
• Check that the INPUT MODE is not set to
"AUTO" (page 108) and the "Input
Assign" function is not used to reassign
the audio input of another source to the
selected input (page 109).
There is no sound from digital sources
(from COAXIAL or OPTICAL input jack).
• Check that the INPUT MODE is set to
"AUTO" (page 108).

being used.
