Troubleshooting
—Continued
The surround back speakers produce no sound
• The surround back speakers are not used with all lis-
tening modes. Select another listening mode (page 92).
• Not much sound may be produced by the surround
back speakers with some sources.
• Make sure the speakers are configured correctly (page 106).
• While Powered Zone 2 is being used, playback in the
main room is reduced to 5.1-channels and the sur-
round back speakers produce no sound (page 140).
The subwoofer produces no sound
• When you play source material that contains no infor-
mation in the LFE channel, the subwoofer produces
no sound.
• Make sure the speakers are configured correctly (page 106).
The Zone 2/3 speakers produce no sound
• The Zone 2/3 speakers only output sources that are
connected to an analog input. Check to see if the
source component is connected to an analog input.
There’s no sound with a certain signal format
• Check the digital audio output setting on the source
component. On some game consoles, such as those
that can play DVDs, the default setting is off.
• With some DVD-Video discs, you need to select an
audio format from a menu or with the [Audio] button
on your DVD player’s remote controller.
• Depending on the input signal, some listening modes
cannot be selected (pages 93-98).
Can’t get 6.1- or 7.1-channel playback
• While Powered Zone 2 is being used, playback in the
main room is reduced to 5.1-channels and the sur-
round back speakers produce no sound (page 140).
The volume cannot be set as required (The vol-
ume cannot be set to +18.0 dB)
• Check to see if a maximum volume has been set
(page 125).
• After the Automatic Speaker Setup function has been
run, or the volume level of each individual speaker has
been adjusted (pages 67 and 110), the maximum vol-
ume may be reduced.
Noise can be heard
• Using cable ties to bundle audio cables with power
cords, speaker cables, and so on can degrade audio
performance, so don’t use them.
• An audio cable may be picking up interference. Try
repositioning your cables.
The Late Night function doesn’t work
• Make sure the source material is Dolby Digital, Dolby
Digital Plus, and Dolby TrueHD (page 119).
The DVD analog multichannel input doesn’t
work
• Check the DVD multichannel input connections
(page 34).
• Make sure that the multichannel input is assigned to
the input selector (page 56).
• Make sure that the multichannel input is selected
(page 130).
• Make sure that the “Speaker Type” is not set to
“Bi-Amp”. The multichannel DVD input cannot be
used if “Speaker Type” is set to “Bi-Amp” (page 57).
• Check the audio output settings on your DVD player.
About DTS signals
• When DTS program material ends and the DTS bit-
stream stops, the AV receiver remains in DTS listening
mode and the DTS indicator remains on. This is to pre-
vent noise when you use the pause, fast forward, or fast
reverse function on your player. If you switch your
player from DTS to PCM, because the AV receiver does
not switch formats immediately, you may not hear any
sound, in which case you should stop your player for
about three seconds, and then resume playback.
• With some CD players, you won’t be able to playback
DTS material properly even though your player is
connected to a digital input on the AV receiver. This is
usually because the DTS bitstream has been processed
(e.g., output level, sampling rate, or frequency
response changed) and the AV receiver doesn’t recog-
nize it as a genuine DTS signal. In such cases, you
may hear noise.
• When playing DTS program material, using the pause,
fast forward, or fast reverse function on your player
may produce a short audible noise. This is not a mal-
function.
The beginning of audio received by an HDMI IN
can’t be heard
• Since it takes longer to identify the format of an
HDMI signal than it does for other digital audio sig-
nals, sound may not be output immediately.
There’s no picture
• Make sure that all video connecting plugs are pushed
in all the way (page 29).
• Make sure that each video component is properly con-
nected (pages 32-45).
• On your TV, make sure that the video input to which
the AV receiver is connected is selected.
