Symptom
Remedy
Broadcast stations cannot be
selected automatically, or
there is considerable noise in
radio broadcasts.
For FM broadcasts
• Fully extend the FM wire antenna, adjust the position for best reception and secure to a wall, etc.
• Use an outdoor antenna for better reception (see page 37).
For AM broadcasts
• Adjust the position and direction of the AM antenna.
• Use an outdoor antenna for better reception (see page 37).
• Noise may be caused by interference from other equipment, such as a fluorescent light, motor,
etc. Switch off or move the other equipment, or move the AM antenna.
A multichannel DVD source
appears to be downmixed to 2
channels during playback.
• Make sure that the multichannel analog inputs are selected (see
Selecting the multichannel analog
inputs
on page 51).
Noise is output when scanning
a DTS CD.
• This is not a malfunction of the receiver. The scan function of your player alters the digital
information, making it unreadable, resulting in noise being output. Lower the volume when
scanning.
When playing a DTS format LD
there is audible noise on the
soundtrack.
• Make sure that the input signal type is set to
DIGITAL
(see
Choosing the input signal
on page 68).
Can’t record audio.
• You can only make a digital recording from a digital source, and an analog recording from an
analog source.
• For digital sources, make sure that what you’re recording isn’t copy protected.
• Check that the
OUT
jacks are properly connected to the recorders input jacks (see
Connecting
other audio components
on page 35).
Subwoofer output is very low.
• To route more signal to the subwoofer, set it to
PLUS
or set the front speakers to
SMALL
(see
Speaker Setting
on page 124).
