No sound from the surround or
center speakers. • Check that the stereo mode or the Front Stage Surround Advance mode isn’t selected; select one of the
surround listening modes (see
Listening in surround sound on page 27).
• Check that the surround/center speakers are not set to NO (see Speaker Setting on page 46).
• Check the channel level settings (see Channel Level on page 47).
• Check the speaker connections (see Connecting the speakers on page 17).
No sound from surround back
speakers. • Check that the surround back speakers are set to LARGE or SMALL (see Speaker Setting on page 46).
• Make sure surround back processing is set to SBch ON (see Using surround back channel processing on
page 30).
• 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 30).
• 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 27).
• 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.
No sound from subwoofer. • 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 46).
• 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 46).
• 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 46).
• Check that the LFE Attenuate setting is not set to OFF , or a very quiet setting (see Setting the AV options

• Check the speaker level settings (see Channel Level on page 47).
• Check that the speaker hasn’t been set to NO (see Speaker Setting on page 46).
• 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 27).
Sound is produced from analog
components, but not from digital
ones (DVD, LD, CD-ROM etc.). • Check that the input signal type is set to DIGITAL (see Choosing the input signal on page 30).
• 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 56).
• 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.

• If the source component has a digital volume control, make sure this is not turned down.
Symptom Remedy
Symptom Remedy
Broadcast stations cannot be
selected automatically, or there is
considerable noise in radio
broadcasts. 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.
A multichannel DVD source
appears to be downmixed to 2
channels during playback. • Make sure that the multichannel analog inputs are selected (see Selecting the multichannel analog inputs
on page 52).
Noise is output when scanning a
DTS CD. • 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.
