Troubleshooting—Continued
The surround back speakers produce no sound
• The surround back speakers are not used with all lis-
tening modes. Try another listening mode (page 55).
• Not much sound may be produced by the surround
back speakers with some sources.
• Check the Speaker Configuration (page 67).
• 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 77).
The subwoofer produces no sound
• If the source material contains no audio in the LFE
channel, the subwoofer produces no sound.
• Check the Speaker Configuration (page 67).
The Zone 2 speakers produce no sound
• The Zone 2 speakers only output sources that are con-
nected to an analog input. Check to see if the source
component is connected to an analog input.
• Powered Zone 2 cannot be used if Speaker Sp Type is
set to Bi-Amp (page 38).
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.
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 77).
Can't select the Pure Audio listening mode
• The Pure Audio listening mode cannot be selected
while Zone 2 is on.
• The Pure Audio listening mode is not available on the
North American model.
The volume cannot be set to 79 (99)
• Check to see if a maximum volume has been set
(page 73).
• After the Automatic Speaker Setup function has been
run, or the volume level of each individual speaker has
been adjusted (pages 36 and 70), the maximum vol-
ume may be reduced.
• When the levels of each speaker have been adjusted
(page 70), the maximum possible volume 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.
• When the Equalizer setting (page 71) is set to
Audyssey, the maximum possible volume is reduced
by 6 dB.
The Late Night function doesn't work
• Make sure that the source is Dolby Digital (page 64).
The analog multichannel input doesn't work
• Check the multichannel input connections (page 24).
• Make sure that the multichannel input is selected
(page 45).
• Check the audio output settings on your DVD player.
About DTS signals
• 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.
• 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, as the AV receiver does not
switch formats immediately, you may not hear any-
thing, in which case you should stop your player for
about 3 seconds, and then resume playback.
• With some CD players, you won't be able to playback
DTS material properly even though your player is con-
nected 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.
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.
Video
There's no picture
• Make sure that all video connecting plugs are pushed
in all the way (page 20).
• Make sure that each video component is properly con-
nected.
• On your TV, make sure that the video input to which
the AV receiver is connected is selected.
• While the Pure Audio listening mode is selected, the
video circuitry is turned off and only the HDMI OUT
outputs video signals.
• The AV receiver does not convert between formats, so
if a video source component is connected to a compo-
nent video input, your TV must be connected to the
component video output (page 21).
• If the video source is connected to an HDMI input,
your TV must be connected to the HDMI OUT
(page 21).
