Troubleshooting
If you think something is wrong with the unit, perform the checks listed here. Often, a minor error in operation may be
mistaken for a malfunction. In addition, the symptom may have been caused by other nearby devices, so checks should
also be made of components being used concurrently. If the
following checks do not remedy the problem, consult the store
where you purchased the unit, or your nearest Pioneer service station.
• Static electricity and other environmental factors may cause the unit to operate erratically. In such cases, the problem
may be rectifi ed by disconnecting the power plug, then plugging
it in again. If this does not remedy the problem, consult
the store where you purchased the unit, or your nearest Pioneer service station.
Symptom Cause Remedy
Power turns off by itself. Auto power down is set (ON). Set auto power down to OFF (see page 10).
No sound is produced even
after selecting the input.
The input connection is wrong. Check the input connection.
The MUTE function has been enabled. Press the remote control’s
MUTE
button to
disable the MUTE function.
Sound
is set too low. Adjust the sound volume.
The output selector has not been set. Rotate the front-panel
OUTPUT
knob to change
the output mode. If the output is from the
analog output connector, choose LINE.
Noise is audible even when no
input is connected.
Noise may result from the power source itself. Check
whether the unit is connected to the
same extension cord used to power a computer
or other digital appliance.
Sound is interrupted or has
dropouts.
The lock range setting is too narrow. Except under normal usage conditions, audio
dropout caused by an excessively narrow
lock range setting falls beyond the range of
warranted operation. Widen the lock range
setting until the dropouts cease (see page 10).
Depending on the device connected, the sound
may experience dropouts when Up Sampling is
used to raise the sampling frequency.
Set the Up Sampling value to LOW; if dropouts
continue, set to OFF (see page 9).
No sound
is produced when
using a digital input.
The digital connection is incorrect. Check the digital connector and make sure it is
connected properly.
When connected to a CD player or other device
equipped with a digital output adjustment
function, the digital output is set too low.
Properly adjust the player’s
digital output
setting.
The output device’s digital format is not supported. If the output device is set for any signal format
other than PCM (Dolby Digital, DTS, etc.),
change the setting to PCM.
Digital inputs above 96
kHz produce no sound, or
intermittent sound.
Some coaxial and optical digital cables may not
transmit
the output signal properly.
Tr y using a different coaxial or optical digital
cable.
Remote control doesn’t work. • The remote control’s batteries are dead.
• The distance between the unit and the remote

the unit.
• A fl uorescent lamp or other strong light
source is shining into the unit’s remote
sensor.
• Change the batteries.
• Operate the remote control within a distance
no more than 7 meters from the unit, and at
an angle within 30° to right or left of
the unit’s
midline.
• Remove the obstacle, or change the position
from which you operate the remote control.
• Move the lamp, or otherwise prevent strong
light from striking the sensor.
