TX-NR7100 - Troubleshooting: Audio/Sound

Problems may be solved by simply turning the power on/off or disconnecting/connecting the power cord, which is easier than working on the connection, setting and operating procedure.

If you can’t resolve the issue yourself, try resetting the AV receiver before contacting your Onkyo dealer. 

• This unit contains a microPC for signal processing and control functions. In very rare situations, severe interference, noise from an external source, or static electricity may cause it to lockup. In the unlikely event that this happens, unplug the power cord from the wall outlet, wait at least 5 seconds, and then plug it back in. 
• We are not responsible for reparations for damages (such as CD rental fees) due to unsuccessful recordings caused by the unit’s malfunction. Before you record important data, make sure that the material will be recorded correctly. 

Resetting the unit (this resets the unit settings to the default) 

If the restart of the unit does not solve the problem, reset the unit, and restore all the settings to the factory default at the time of purchase. This may solve the problem. If the unit is reset, your settings are restored to the default values. Be sure to note down your setting contents before performing the following operations. Note that it is not possible to reset the unit during the Initial Setup process. Before doing the following procedures, press [BACK] to exit Initial Setup. 

1. While pressing and holding CBL/SAT of the input selector on the main unit with the unit turned on, press the ON/STANDBY button.

 2. "Clear" is displayed on the display, and the unit returns to the standby state. Do not remove the power cord until "Clear" disappears from the display. 

To reset the remote controller, while pressing and holding MODE, press the CLEAR button at least 3 seconds.

Before you start...

•  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 "MUTING" is displayed on the display and is blinking, 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" on the Setup menu is set to "On", audio is not played if signals other than PCM are input. Change the setting to Off.

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

Noise can be heard

• Using cable ties to bundle analog audio 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.

Sound suddenly changes

• When "My Input Volume" is set, the volume is set for each input selector. Check "4. Source" - "My Input Volume" on the Setup menu.
