TX-SR393- Troubleshooting: Audio

• Make sure that the speaker setup microphone is no longer connected.
• Confirm that the connection between the output jack on the connected device and the input jack on this unit is correct.
• Make sure that none of the connecting cables are bent, twisted, or damaged.
• If the MUTE indicator on the display blinks, press on the remote controller to cancel muting.
• While headphones are connected to the PHONES jack, no sound is output from the speakers.
• When "4. Source" - "Audio Select" - "PCM Fixed Mode" in the Setup menu is set to "On", no sound is played if signals other than PCM are input.
Change the setting to Off.
Check the following if the problem persists after you have confirmed the above.

No sound from the TV
• Change the input selector on this unit to the position of the terminal to which the TV is connected.
• If the TV does not support the ARC function, along with the connection by an HDMI cable, connect the TV with this unit using a digital optical cable. ( p28)
No sound from a connected player
• Change the input selector on this unit to the position of the terminal to which the player is connected.
• Check the digital audio output setting on the connected device. On some game consoles, such as those supporting DVD, the default setting may be off.
• For some DVD-Video discs, you need to select an audio output format from a menu.
A speaker produces no sound
• Make sure that the polarity (+/-) of the speaker cables is correct, and that no bare wires are in contact with the metal part of speaker terminals.
• Make sure that the speaker cables are not shorting out.
• Check "Connect the Speaker Cables" ( p21) to see if the speaker connections have been made correctly. Settings for the speaker connection environment need to be made in "Speaker Setup" in Initial Setup. Check "Initial Setup with Auto Start-up Wizard" ( p79).
• Depending on the input signal and listening mode, not much sound may be output from speakers. Select another listening mode to see if sound is output. ( p21)
The subwoofer produces no sound
If the setting of the front speakers is "Full Band", the low range elements will be output from the front speakers instead of from the subwoofer during
2 ch audio input of TV or music. To output the sound from the subwoofer, make one of the following settings.
1. Change the setting for the front speakers to a setting of crossover frequency value other than "Full Band".
The range below the specified frequency will be output from the subwoofer instead of from the front speakers. If your front speakers have a high
low-range reproduction capability, changing this setting is not recommended.
2. Change "Double Bass" to "On".
The low range elements of the front speakers will be output from both the front speakers and the subwoofer. Due to this, the bass sound may be
emphasized too much. In such a case, do not change the setting, or make the setting with the above option 1.
      • For the setting details, refer to "2. Speaker" - "Crossover" in the Setup menu.
      • If the input signals do not contain subwoofer audio elements (LFE), the subwoofer may produce no           sound. ( p67)
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. Refer to "Speaker Layouts and Selectable Listening Modes" ( p48) or "Input Formats and Selectable Listening Modes" ( p54) in "Listening Mode".
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 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.
