• 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.

L and R jacks of an analog component, and
not only to either the L or R jack. Use an

jack.
