A-9110 - Troubleshooting: Audio
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. After reconnecting, turn off and on the unit and the connected device.
- 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)
Resetting the unit to the status at the time of shipment 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 the power is on, press ON/STANDBY while pressing DIRECT.
Before you start...
- Confirm that the connection between the output jack on
the 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 active, press MUTING on the remote
controller to cancel. MUTING is active when the indicator
for the selected input source is blinking.
- While headphones are connected to the PHONES jack,
no sound is output from the speakers or subwoofer.
- Audio performance will be at its best about 10 to 30
minutes after the integrated amplifier has been turned on
and had time to warm up.
- The sound quality can be affected by strong magnetic
fields, such as those from a TV. Try moving any such
devices away from the integrated amplifier.
- If you have any devices that emit high-intensity radio
waves near the integrated amplifier, such as a cellular
phone that’s being used to make a call, the integrated
amplifier may output noise.
- Install the integrated amplifier on a sturdy rack or shelf.
Position it so that its weight is evenly dispersed on its four
insulators. Do not install the integrated amplifier in a place
with vibration or an unstable location.
No sound from a connected playback device
- Change the input selector on this unit to the position of
the terminal to which the playback device is connected.
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 have not shorted.
- Make sure the speakers are connected correctly.
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 cords.
- An audio cable may be picking up interference. Try
repositioning your cables.
Headphone output is intermittent or there’s no sound
- The connection part may be dirty. Clean the headphones
plug. See your headphones’ instruction manual for
cleaning information. Also, make sure that the
headphones cable is not broken or damaged.
