Troubleshooting
Listening Modes
• To enjoy digital surround playback in formats such as Dolby Digital, you need to make a connection for audio signals with an HDMI cable, digital
coaxial cable or digital optical cable. Also, audio output need to be set to Bitstream output on the connected Blu-ray Disc player, etc.
• Press on the remote controller several times to switch the display of the main unit, and you can check the input format.
Check the following if the problem persists after you have conrmed the above.
Cannot select a desired listening mode
• Depending on the connection status of the speaker, some listening modes may not be selected. Check "Speaker Layouts and Selectable
Listening Modes" ( →p192) or "Input Formats and Selectable Listening Modes" ( →p197).
Cannot listen to the sound in Dolby TrueHD, Dolby Atmos or DTS-HD Master Audio format
• If the audio in Dolby TrueHD, Dolby Atmos or DTS-HD Master Audio format cannot be output correctly in the source format, set "BD video
supplementary sound" (or reencode, secondary sound, video additional audio, etc.) to "O" in the setting of a connected Blu-ray Disc player, etc.
After changing the setting, switch the listening mode to that for each source, and conrm.
About Dolby signals
• When surround back speakers are included in the speaker layout, and software that is recorded with the 5.1-channel Dolby audio format is
played, the surround channel audio may be output from the surround back speakers.
• Some Dolby Atmos audio format that is used on games, etc., may be recognized as "Multichannel PCM". If this occurs, check the rmware
updates for the game console.
About DTS signals
• With media that switches suddenly from DTS to PCM, PCM playback may not start immediately. In such a case, stop playback on the player side
for approx. 3 seconds or more. Then, resume playback. The playback will be performed normally.
• DTS playback may not be performed normally on some CD and LD players even if the player and this unit are digitally connected. If some
processing (e.g., output level adjustment, sampling frequency conversion, or frequency characteristic conversion) has been executed for the
DTS signal being output, this unit cannot recognize it as a genuine DTS signal, and noise may occur.
• While playing a DTS-compatible disc, if a pause or skip operation is performed on your player, noise may occur for a short period. This is not a
malfunction.
