Remedy
• Check that the front height or front wide speakers are set to LARGE or SMALL, and the surround
speakers are not set to NO (see Speaker Setting on page 110).
• Check the speaker connections (see Connecting the speakers on page 23).
• Check that the subwoofer is connected properly, switched on and the volume turned up.
• If your subwoofer has a sleep function, make sure it is switched off.
• Make sure that the Subwoofer setting is YES or PLUS (see Speaker Setting on page 110).
• The crossover frequency may be set too low; try setting it higher to match the characteristics of
your other speakers (see Speaker Setting on page 110).
• If there is very little low frequency information in the source material, change your speaker settings
to Front: SMALL / Subwoofer: YES, or Front: LARGE / Subwoofer: PLUS (see Speaker Setting on
page 110).
• Check that the LFE channel is not set to OFF, or to a very quiet setting (see Setting the Audio options
on page 71).
• Check the speaker level settings (see Channel Level on page 111).
• Check the speaker connection (see Connecting the speakers on page 23).
• Check the speaker level settings (see Channel Level on page 111).
• Check that the speaker hasn't been set to NO (see Speaker Setting on page 110).
• The channel may not be recorded in the source. By using one of the advanced effect listening
modes, you may be able to create the missing channel (see Listening in surround sound on page 55).
• Check that the input signal type is set to DIGITAL (see Choosing the input signal on page 58).
• 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 45).
• 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 BD or DVD player is compatible with Dolby Digital/DTS discs.
• Check the digital output settings or the HDMI audio output settings of your BD or 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 36).
For AM broadcasts
• Adjust the position and direction of the AM antenna.
• Use an outdoor antenna for better reception (see page 36).
• 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.
• 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 58).
• 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 the
multichannel analog inputs on page 33).
• To route more signal to the subwoofer, set it to PLUS or set the front speakers to SMALL (see
Speaker Setting on page 110).
