Remedy
• Check the speaker connection (see Connecting the speakers on page 19).
• Check the speaker level settings (see Channel Level on page 92).
• Check that the speaker hasn't been set to NO (see Speaker Setting on page 91).
• The channel may not be recorded in the source. By using one of the advanced effect listening
mode, you may be able to create the missing channel (see Listening in surround sound on page 56).
• Check that the input signal type is set to DIGITAL (see Choosing the input signal on page 61).
• Make sure that the digital input is assigned correctly for the input jack the component is connected
to (see The Input Setup menu on page 43).
• Check the digital output settings on the source component.
• If the source component has a digital volume control, make sure this is not turned down.
• Make sure that the multichannel analog inputs are not selected. Select any other input function.
• Check that your DVD player is compatible with Dolby Digital/DTS discs.
• Check the digital output settings of your DVD player. Make sure that the DTS signal output is set
to On.
• If the source component has a digital volume control, make sure this is not turned down.
• If the HDMI input function is selected, sound is muted until exiting the HOME MENU.
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 31).
For AM broadcasts
• Adjust the position and direction of the AM antenna.
• Use an outdoor antenna for better reception (see page 31).
• 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 46).
• 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 61).
• 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 route more signal to the subwoofer, set it to PLUS or set the front speakers to SMALL (see
Speaker Setting on page 91).
• 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 19).
• 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 93).
• Check that personal computers or other digital components connected to the same power source
are not causing interference.
