Troubleshooting—Continued
The surround speakers produce no sound
• When the DTS Surround Sensation, T-D (Theater-
Dimensional), Stereo or Mono listening mode is
selected, the surround speakers produce no sound.
• Depending on the source and current listening mode,
not much sound may be produced by the surround
speakers. Try selecting another listening mode.
• Make sure the speakers are configured correctly
(page 85).
The center speaker produces no sound
• When the DTS Surround Sensation or Stereo listening
mode is selected, the center speaker produces no
sound.
• In the Mono listening mode, only the front speakers
output sound if the “Output Speaker” setting is set to
“Left/Right” (page 89).
• Make sure the speakers are configured correctly
(page 85).
The front high, front wide and surround back
speakers produce no sound
• Depending on the current listening mode, no sound
may be produced by the front high, front wide, and
surround back speakers. Select another listening mode
(page 81).
• Not much sound may be produced by the front high,
front wide, and surround back speakers with some
sources.
• Make sure the speakers are configured correctly
(page 85).
• While Powered Zone 2 is being used, playback in the
main room is reduced to 5.1-channels and the front
high and front wide speakers produce no sound
(page 115).
The subwoofer produces no sound
• When you play source material that contains no infor-
mation in the LFE channel, the subwoofer may pro-
duce no sound.
• Make sure the speakers are configured correctly
(page 85).
There’s no sound with a certain signal format
• Check the digital audio output setting on the con-
nected device. On some game consoles, such as those
that support DVD, the default setting is off.
• With some DVD-Video discs, you need to select an
audio output format from a menu.
• Depending on the input signal, some listening modes
cannot be selected (pages 75-80).
Can’t get 6.1/7.1 playback
• If no front high, front wide and surround back speak-
ers are connected, or the Zone 2 speakers are being
used, 6.1/7.1 playback is not possible.
• You can not always select all of the listening modes,
depending on the number of the speakers connected
(pages 75-80).
The speaker volume cannot be set as required
(The volume cannot be set to +18.0 dB)
• Check to see if a maximum volume has been set
(page 98).
• If the volume level of each individual speaker has been
adjusted to high positive values (page 87), then the
maximum master volume possible may be reduced.
Note that the individual speaker volume levels are set
automatically after Audyssey MultEQ
®
Room Cor-
rection and Speaker Setup has been completed
(page 55).
Noise can be heard
• Using cable ties to bundle audio cables with power
cords, speaker cables, and so on may degrade the
audio performance, so don’t do it.
• 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 104).
About DTS signals
• When DTS program material ends and the DTS bit-
stream stops, the AV receiver remains in DTS listen-
ing mode and the DTS indicator remains on. This is to
prevent 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 play-
back.
• With some CD and LD 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 recognize 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, audio output may not start immediately.
