Remedy
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 30).
For AM broadcasts
• Adjust the position and direction of the AM antenna.
• Use an outdoor antenna for better reception (see page 30).
• 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.
• Make sure that the multichannel analog inputs are selected (see Selecting the
multichannel analog inputs on page 43).
• 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.
• Make sure that the input signal type is set to DIGITAL (see Choosing the input
signal on page 57).
• 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 29).
to SMALL (see Speaker Setting on page 94).
• The speakers may be out of phase. Check that the positive/negative speaker
terminals on the receiver are matched with the corresponding terminals on the
speakers (see Connecting the speakers on page 18).
• If applicable, check that the lowpass filter switch on your subwoofer is off, or
the lowpass cutoff is set to the highest frequency setting. If there is a PHASE
setting on your subwoofer, set it to 0º (or depending on the subwoofer, the
setting where you think it has the best overall effect on the sound).
• Make sure the speaker distance setting is correct for all speakers (see Speaker
Distance on page 96).
• Check that personal computers or other digital components connected to the
same power source are not causing interference.
• See Automatically setting up for surround sound (Auto MCACC) on page 37 to
set up your system again using MCACC (this will automatically compensate for
a delay in the subwoofer output).
• Check that the Volume Limit is set to OFF (see Volume Limit Setup on
page 99).
