Troubleshooting
If you have any trouble using the integrated amplifier,
look for a solution in this section.
If you can't resolve the issue yourself, try resetting the
integrated amplifier before contacting your Onkyo dealer.
To reset the integrated amplifier to its factory defaults, see
“Restoring the Default Settings” (➔ page 40).
• Make sure the POWER switch is set to ON.
• Make sure that the power cord is properly plugged into
the wall outlet (➔ page 18).
• Unplug the power cord from the wall outlet, wait 5
seconds or more, then plug it in again.
• When the Auto Standby function is activated, the
integrated amplifier will automatically enter Standby
mode (➔ page 38).
• When the protection circuit is activated (because of
speaker short-circuit, overload, or over-current), the
integrated amplifier enters Standby mode. Remove the
source of the problem and turn the integrated amplifier
back on.
• Make sure the POWER switch is set to ON.
• Make sure the integrated amplifier’s volume control is
not set to minimum (➔ page 29).
• Make sure the correct input source is selected
(➔ page 29).
• Make sure the integrated amplifier is not muted
(➔ page 31).
• Make sure the speakers are connected correctly
(➔ page 15).
• Check all connections and correct as necessary
(➔ page 15).
• While headphones are connected, the speakers and PRE
OUT output no sound (➔ page 32).
• The integrated amplifier does not support digital formats
other than PCM. Inputting a digital format other than
PCM will cause loud noise.
• If the USB connector of your PC does not support the
high-speed 2.0 standard, then audio is not output.
• If “ROUTE” is set to anything other than “NORMAL”,
make sure that each component is connected accordingly
(➔ pages 25 to 27, 39).
• Make sure the speaker cables are connected with the
correct polarity (➔ page 15).
• Make sure all audio connecting plugs are pushed in all
the way (➔ page 17).
• 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.
• This may be due to dirty contacts. Clean the headphones
plug. See your headphones’ instruction manual for
cleaning information. Also, make sure that the
headphones cable is not broken or damaged.
• Make sure that “ROUTE” is not set to “MAIN”
(➔ page 39).
• 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.
• Using cable ties to bundle audio cables with speaker or
power cables may degrade the sound quality, so refrain
from doing it.
• Depending on the country, the integrated amplifier may
be polarity-sensitive. In this case, plug the power cord in
a way that provides the best sound quality.
• Install the integrated amplifier on a sturdy rack or shelf.
Position it so that its weight is evenly dispersed on its
four legs. Do not install the integrated amplifier in a
place with vibration or an unstable location.
• Plug the power cord into an AC wall outlet.
