Troubleshooting
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 doesn't support the ARC function, along with connection by HDMI, connect the TV and this unit using a digital optical cable or analog
audio cable.

No sound from a connected player
• Change the input selector on this unit to the position of the jack 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" ( →p39) 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" ( →p158).
• 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.
• If surround back speakers are installed, be sure to install surround speakers as well.
• A maximum of 7.1 c h playback is possible when Bi-Amping connection is used. Be sure to remove the jumper bar on the speakers when using
Bi-Amping connection.

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 specied 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" on the Setup menu.
• If the input signals do not contain subwoofer audio elements (LFE), the subwoofer may produce no sound.
