a digital optical cable, digital coaxial cable, or analog
audio cable.
No sound from a connected player
0 Change the input selector on this unit to the position of

from the subwoofer. If you would rather output from the
subwoofer, make one of the following settings.
1. Change the front speakers settings to a setting other
than "Full Band" for the crossover frequency value.
The range below the frequency you specify will be output
from the subwoofer rather than the front speakers. We
do not recommend changing this if your front speakers
have good low range reproduction capabilities.
2. Change "Double Bass" to "On".
The low range elements will be output from both the front
speakers and the subwoofer. This may mean that there
is too much bass. Do not change if this happens, or
choose option 1.
0 Refer to "2. Speaker" - "Crossover" (P37) in the Setup
menu for details.
0 When you play source material that contains no
information in the LFE channel, the subwoofer produces
no sound.
Noise can be heard
0 Using cable ties to bundle analog audio cables, power
cords, speaker cables, etc. may degrade the audio
performance, Do not bundle cords.
0 An audio cable may be picking up interference. Try
repositioning your cables.
The beginning of audio received by an HDMI IN cannot
be heard
0 Since it takes longer to identify the format of an HDMI
signal than it does for other digital audio signals, audio
output may not start immediately.
Sound suddenly reduces
0 When the temperature inside the unit exceeds a certain
temperature for extended periods, the volume may be
reduced automatically to protect the circuits.
