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 20).
For AM broadcasts
• Adjust the position and direction of the AM antenna.
• Use an outdoor antenna for better reception (see page 20).
• 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 50).
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 29).
