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 23).
For AM broadcasts
• Adjust the position and direction of the AM antenna.
• Use an outdoor antenna for better reception (see page 23).
• 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 58).
• 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 33).
• 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
analog audio sources on page 20).
• To route more signal to the subwoofer, set it to PLUS or set the front speakers to SMALL (see
Speaker Setting on page 48).
• 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 21).
• 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 50).
• 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 10 to set up your system
again using MCACC (this will automatically compensate for a delay in the subwoofer output).
• Make sure that HDMI Control is set to OFF (see Setting the HDMI Control mode on page 65).
• This is not a malfunction. If the levels in Channel Level on page 49 have been adjusted, the
maximum volume will change accordingly.
