Troubleshooting
Noise can be heard
• Using cable ties to bundle audio pin cables, power cords, speaker cables, etc. may degrade the audio performance. Do not bundle the cords.
• An audio cable may be picking up interference. Change the position of the 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 using the unit for extended periods with the temperature inside the unit exceeding a certain temperature, the volume may be reduced
automatically to protect the circuits.
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 confirmed 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" (
→p148
) or "Input Formats and Selectable Listening Modes" (
→p151
).
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 "Off" 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 confirm.
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 firmware
updates for the game console.
