to be made in "AccuEQ Room Calibration" in Initial
Setup. Check in "Initial Setup" in the Basic Manual.
• Depending on the source and current listening mode,
not much sound may be produced by the surround
speakers. Select another listening mode to see if sound
is output.
• If you are installing surround back speakers (for
compatible models only), surround speakers are
required.
• A maximum of 5.1 ch playback is possible when Bi-
Amping connection is used (for compatible models
only). Further, make sure you remove the jumper bar on
the speakers when using Bi-Amping connection.
■ The subwoofer produces no sound
• When you play source material that contains no
information in the LFE channel, the subwoofer produces
no sound.
■ Noise can be heard
• Using cable ties to bundle audio cables with power
cords, speaker cables, etc. may degrade the audio
performance, so refrain from doing it.
• An audio cable may be picking up interference. Try
repositioning your cables.
■ The beginning of audio received by an HDMI IN
cannot be heard
• 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.
■ Sound suddenly reduces
• When the temperature inside the unit exceeds a certain
temperature for extended periods, the volume may be
reduced automatically to protect the circuits.
Listening Modes
• To enjoy digital surround playback, such as Dolby
Digital, the audio signals need to pass through a
connection via HDMI cable, digital coaxial cable, or
digital optical cable. Audio output should be set to
bitstream output on the connected Blu-ray Disc player
or other device.
• Press on the remote controller several times to
switch the display of the main unit to check the input
format.
Check the following if the above does not fix the problem:
■ Cannot select a desired listening mode
• Depending on the connecting status of the speaker,
some listening modes may not be selected. Check in
"Selectable Listening Modes" in "Listening Modes" in
the Advanced Manual.
■ There is no sound with Dolby TrueHD, Dolby Atmos,
and DTS-HD Master Audio (for compatible models
only)
• You need to connect surround back speakers or height
speakers to enjoy Dolby Atmos. Furthermore, Dolby
Atmos can only be enjoyed when the input signals are
Dolby Atmos.
• If you cannot output formats such as Dolby TrueHD,
Dolby Atmos, or DTS-HD Master Audio according to the
format of the source, in the Blu-ray Disc player settings
try setting BD video supplementary sound (or re-
encode, secondary sound, video additional audio, etc.)
to Off . Change the listening mode for each source
after changing the setting to confirm.
■ Cannot select Pure Audio mode (for compatible
models only)
• The Pure Audio mode cannot be selected while the
Multi-zone feature (for compatible models only) is on.
■ About DTS signals
• With media that switches suddenly from DTS to PCM,
PCM playback may not start immediately. In such
cases, you should stop your player for about 3 seconds
and then resume playback.

Troubleshooting
• 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.
• 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.
