• Make sure the correct input function is selected.
• Check that the MCACC setup microphone is disconnected.
• Make sure the correct input signal is selected (press SIGNAL SEL). Note that when PCM is
selected, you won’t be able to hear any other signal format.
• Check that the source component is connected properly (see Connecting your equipment on
page 14).
• Check that the speakers are connected properly (see Connecting the speakers on page 18).
No sound from the surround or
center speakers. • Check that the Stereo listening 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 50).
• Check that the surround/center speakers are not set to NO (see Speaker Setting on page 85).
• Check the channel level settings (see Channel Level on page 86).
• Check the speaker connections (see Connecting the speakers on page 18).
No sound from surround back
speakers. • Check that the surround back speakers are set to LARGE or SMALL (see Speaker Setting on
page 85).
• Make sure surround back channel processing is set to SBch ON (see Using surround back channel
processing on page 53).
• If the source is Dolby Surround EX or DTS-ES with no flag to indicate 6.1 compatibility, then with
surround back channel 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 53).
• If the source does not have 6.1 playback channels, make sure that surround back channel
processing is set to SBch ON and a surround mode is selected (see Listening in surround sound on
page 50).
• Check the speaker connections (see Connecting the speakers on page 18).
If only one surround back speaker is connected, make sure it’s connected to the left channel speaker
terminal.

• If your subwoofer has a sleep function, make sure it is switched off.

• 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 85).
• 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 85).
• Check that the LFE channel is not set to OFF, or a very quiet setting (see Setting the Audio options
on page 60).
