When the Stereo or Mono listening mode is selected,
only the front speakers and subwoofer produce sound.
r
Make sure the speakers are configured correctly.
Only the center speaker produces sound
r
If you use the Dolby Surround listening mode with a
mono source, such as an AM radio station or mono
TV program, the sound is concentrated in the center
speaker.
r
Make sure the speakers are configured correctly.
The surround speakers produce no sound
r
When the T-D (Theater-Dimensional), Stereo or Mono
listening mode is selected, the surround speakers
produce no sound.
r
Depending on the source and current listening mode,
not much sound may be produced by the surround
speakers. Try selecting another listening mode.
r
Make sure the speakers are configured correctly.
The center speaker produces no sound
r
When the Stereo or Mono listening mode is selected,
the center speaker produces no sound.
r
Make sure the speakers are configured correctly.
There is no sound from surround back speakers,
height speakers or wide speakers.
r
Depending on the source or current listening mode, not
much sound may be output from speakers. Try selecting
another listening mode.
r
Make sure the settings for the speakers are made
correctly.
The subwoofer produces no sound
r
When you play source material that contains no
information in the LFE channel, the subwoofer produces
no sound.
r
Make sure the speakers are configured correctly.
There is no sound with a certain signal format
r
When listening to Dolby Digital and/or DTS sound,
digital connection is necessary.
r
Check the digital input terminal setting. If the connection
is different from the default, re-setting is necessary.
r
Check the digital audio output setting on the connected
component. On some game consoles, such as those
that support DVD, the default setting is off.
There is no sound with Dolby Atmos signal format
r
Make sure the surround back speakers, the height
speakers or the wide speakers are connected and
configured as connected in the "Speaker Configuration".
r
Make sure the input signal is the Dolby Atmos format.
Cannot select a desired listening mode
r
Depending on the connecting status of the speaker,
some listening modes may not be selected. Check the
details in "Using the Listening Modes" section.
Cannot play 5.2 ch
r
Make sure the speakers are configured correctly.
r
Not all listening modes use all speakers.
Cannot get 6.2 ch/7.2 ch playback
r
6.2 ch/7.2 ch playback is not possible if surround back
speakers, height speakers and wide speakers are not
connected.
r
Depending on the number of connected speakers, it is
not always possible to select all of the listening modes.
The speaker volume cannot be set as required
r
Check to see if a maximum volume has been set.
Noise can be heard
r
Using cable ties to bundle analog audio (RCA) cables
with power cords, speaker cables, etc. may degrade the
audio performance, so refrain from doing it.
r
An analog audio (RCA) cable may be picking up
interference. Try repositioning your cables.
The Late Night function does not work
r
Make sure the source material is Dolby Digital, Dolby
Digital Plus, or Dolby TrueHD.
About DTS signals
r
When DTS program material ends and the DTS
bitstream stops, the unit remains in DTS listening 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, you may not hear any sound because the
unit does not switch formats immediately. In such case,
you should stop your player for about 3 seconds and
then resume playback.
r
With some CD and LD players, you will not be able
to playback DTS material properly even though your
player is connected to a digital input on the unit. This is
usually because the DTS bitstream has been processed
(e.g., output level, sampling rate, or frequency response
changed) and the unit does not recognize it as a
genuine DTS signal. In such cases, you may hear noise.
r
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 malfunction.
The beginning of audio received by an HDMI IN
cannot be heard
r
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.
Video
There is no picture
r
Make sure that all video connecting plugs are pushed in
all the way.
r
Make sure that each video component is properly
connected.
r
If the TV is connected to the HDMI OUT jack of the unit,
set "Monitor Out" to "MAIN" or "SUB" according to the
output jack. If the playback source is connected to the
composite video jack or component video jacks and you
want to output the video to the TV via the HDMI OUT
jack, set "HDMI Input" to "-----".
r
If the video source is connected to a component video
input, you must assign that input to an input selector,
and your TV must be connected to COMPONENT
VIDEO OUT terminal.
r
If the video source is connected to a composite video
input, your TV must be connected to the MONITOR OUT
V terminal.
r
If the video source is connected to an HDMI input, you
must assign that input to an input selector, and your TV
must be connected to the HDMI output(s).
r
Make sure the switching of input screens is proper at the
monitor side such as a TV.
