Troubleshooting
—Continued
There’s no sound with a certain signal format?
• Check the input signal format setting. Depending on
the playback source, you can select Auto, Multich,
Analog, DTS, or PCM (page 53).
• Check the digital audio output setting on the con-
nected device. On some games 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 (page 58).
Can’t select the DTS-ES Discrete/Matrix or THX
Surround EX listening modes?
• These modes cannot be selected when no surround
back speakers are connected, or Zone 2 is being used.
Can’t get 6.1 or 7.1 playback?
• If no surround back speakers are connected, or Zone 2
is being used, 6.1 and 7.1 playback is not possible.
The volume cannot be set above 99?
• When the levels of all speakers have been calibrated
(page 44), the maximum volume setting may change.
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
(page 62).
The multichannel input doesn’t work?
• Check the MULTI CH INPUT connections (page 29).
• Make sure that the multichannel input is assigned to
the correct input source (page 63).
• Set the audio input signal format to Multich (page 53).
About DTS signals
• When DTS program material ends and the DTS bit-
stream stops, the DTR-8.4 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 DTR-8.4 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 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 DTR-8.4.
This is usually because the DTS bitstream has been
processed (e.g., output level, sampling rate, or fre-
quency response changed) and the DTR-8.4 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.
There’s no picture?
• Make sure that all video connecting plugs are pushed
in all the way (page 26).
• Make sure that each video component is properly con-
nected.
• If your video component is connected to a component
video input, your TV must be connected to the compo-
nent video output, unless the Component Video setting
is set to VIDEO (page 47).
• On your TV, make sure that the video input to which
the DTR-8.4 is connected is selected.
• While the Pure Audio listening mode is selected, the
video circuits are turned off and the DTR-8.4 outputs
no video signals.
The onscreen menus (OSD) don’t appear, or
they appear in an odd position?
• Make sure that the video settings are correct
(page 46).
• Check the Display Position and OSD Position settings
(page 73).
• On your TV, make sure that the video input to which
the DTR-8.4 is connected is selected.
Reception is noisy, FM stereo reception is
noisy, or the FM STEREO indicator doesn’t
appear?
• Relocate your antenna.
•Move the DTR-8.4 away from your TV or computer.
•Try using the AUTO FM mode (page 54).
• When listening to an AM station, operating the remote
controller may cause noise.
•Passing cars and airplanes can cause interference.
• Concrete walls weaken radio signals.
• If nothing improves the reception, install an outdoor
antenna.
The remote controller doesn’t work?
• Make sure that the batteries are installed with the cor-
rect polarity (page 8).
• Install new batteries. Don’t mix different types of bat-
teries or old and new batteries (page 8).
• Make sure that the remote controller is not too far
away from the DTR-8.4, and that there’s no obstruc-
tion between the remote controller and the DTR-8.4’s
remote control sensor (page 8).
