Message Explanation

Symptom Cause Remedy
No sound. • The computer settings are incorrect. • Make sure you have set up your computer system to
output through the USB interface (see Using the USB
interface on page 80).
• The software or source material you are
using is not compatible with USB output.
• Update to a more recent version of your existing
software, try a different audio program, or try a different
source.
• The volume control on your computer is set
too low.
• Turn up the volume on your computer.
No sound from one or more
channels.
• The software settings are incorrect, or the
program you are using cannot output
multichannel audio.
• Try changing the software settings. If this doesn’t work,
update to a more recent version of your existing software,
or try a different audio program.
• The wrong input setting is selected for the
USB interface.
• Change the setting accordingly (see Selecting USB and
multichannel analog input channels on page 45).
Symptom Cause Remedy
The amplifier doesn’t seem to
respond when the buttons are
pressed.
• Static electricity caused by dry air. • Switch the power off then on again. If this doesn’t seem
to work, try disconnecting the power plug from the outlet,
and insert again.
One of the Home THX 7.1
channel modes is selected, but
there are certain options that
can't be chosen.
• There is only one surround back speaker
connected or the current settings are for only
one surround back speaker.
• Make sure there are two surround back speakers
connected (see Connecting the speakers on page 24) and
make the necessary settings in Speaker Systems on
page 52.
There seems to be a time lag
between the speakers and the
output of the subwoofer.
• The subwoofer channel can be delayed
slightly if run through a low-pass filter.
• See Automatically setting up for surround sound on
page 35 to set up your system again using MCACC (this
will automatically compensate for a delay in the
subwoofer output).
