Remedy
• Check that the surround back speakers are set to LARGE or SMALL (see Speaker Setting on page 42).
• Make sure surround back processing is set to SBch ON (see Using surround back channel processing on
page 29).
• If the source is Dolby Surround EX or DTS ES with no flag to indicate 6.1 compatibility, then with surround
back processing set to SBch Auto, there will be no sound from the surround back speakers. In this case,
set to SBch ON (see Using surround back channel processing on page 29).
• If the source does not have 6.1 playback channels, make sure that surround back processing is set to
SBch ON and a surround mode is selected (see Listening in surround sound on page 26).
• Check the speaker connections (see Connecting the speakers on page 17). If only one surround back
speaker is connected, make sure it's connected to the left channel speaker terminal.
• 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 42).
• 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 42)
• 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 42).
• Check that the LFE channel is not set to –80dB, or a very quiet setting (see Bass Peak Level on page 44).
• Check the speaker level settings (see Channel Level on page 43).
• Check the speaker connection (see Connecting the speakers on page 17).
• Check the speaker level settings (see Channel Level on page 43).
• Check that the speaker hasn't been set to NO (see Speaker Setting on page 42).
• 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 26).
• Check that the input signal type is set to DIGITAL (see Choosing the input signal on page 29).
• 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 58).
• 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 source.
• 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 sound is muted in the sub room (ROOM 2), it will be restored after exiting the System Setup 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 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.
• Make sure that the multichannel analog inputs are selected (see Selecting the multichannel analog inputs
on page 50).
• 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 29).
