DRX-3.4 - Troubleshooting: Audio – Integra Support

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. Try the simple measures on both the unit and the connected device. If the problem is that the video or audio is not output or the HDMI linked operation does not work, disconnecting/connecting the HDMI cable may solve it. When reconnecting, be careful not to wind the HDMI cable since if wound the HDMI cable may not fit well. After reconnecting, turn off and on the unit and the connected device.

The AV receiver 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.

Try restarting the unit

Restarting this unit may solve the problem. After turning the unit to standby mode, press and hold the On/Standby button of the main unit for at least 5 seconds, and then restart the unit. (The settings on this unit are kept.) If the problem persists after restarting the unit, unplug and plug the power cords of this unit and connected devices or HDMI cable.

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.

While pressing and holding CBL/SAT of the input selector on the main unit with the unit turned on, press the On/Standby button.
"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 the MUTE indicator on the display blinks, press [MUTE] 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 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 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.

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.
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 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.

HDMI linked operation does not work with CEC-compliant devices, such as a TV

In the Setup menu of the unit, set "6. Hardware" - "HDMI" - "HDMI CEC" to "On".
It is also necessary to set HDMI linking on the CEC-compliant device. Check the instruction manual.

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.

Cannot output audio to ZONE B

To output audio to ZONE B, set the audio output destination for "Audio" - "Zone B" on Quick menu to "On(A+B)" or "On(B)" and also set "2. Speaker" - "Configuration" - "Zone 2 Preout" on the Setup menu to "Zone B".

Cannot ZONE-output the audio of externally connected AV components

To output audio from an externally connected AV component to ZONE 2, connect it to any of HDMI IN1 to IN3 jacks. If the AV component is not equipped with an HDMI jack, use a digital coaxial cable, digital optical cable or analog audio cable. Also, the audio from externally connected AV components can be output to ZONE 2 only when the audio is analog or 2ch PCM signal. When the AV component is connected to this unit with an HDMI cable, digital coaxial cable or digital optical cable, change the audio output of the AV component to the PCM output.
When video and audio via HDMI input are output to ZONE 2, set "1. Input/Output Assign" - "TV Out / OSD" - "Zone 2 HDMI" to "Use" on the Setup menu.
To output audio from an externally connected AV component to ZONE 3, use an analog audio cable for connection. Also, audio from externally connected AV components can be output to ZONE 3 only when it is an analog audio signal.
