Symptom Remedy
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 Enjoying various types of play-
back using the listening modes on page 73 ).
Check that the surround/center speakers are not set to NO (see Speaker Setting on page 113 ).
Check the speaker connections (see Connecting the speakers on page 25 ).
No sound from surround back
speakers.
Check that the surround back speakers are set to LARGE or SMALL, and the surround
speakers are not set to NO (see Speaker Setting on page 113 ).
Check the speaker connections (see Connecting the speakers on page 25 ). If only
one surround back speaker is connected, make sure it’s connected to the left channel
speaker terminal.
When Dolby Surround is selected, audio is not output from the surround back speaker
when it is the only one connected (set).
No sound from front height or front
wide speakers.
Check that the front wide speakers are set to LARGE or SMALL, and the surround speak-
ers are not set to NO (see Speaker Setting on page 113 ).
Check the speaker connections (see Connecting the speakers on page 25 ).
When Speaker System is set to 9.2.2ch TMd/FH and SP: TMd ON is selected with the
OUT P. button, no sound will be output from the front height speakers. Select SP: FH ON
or SP: TMd/FH ON (see Switching the speaker terminals on page 92 ).
When Dolby Surround is selected, audio is not output from the front wide speakers.
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 113 ).
The crossover frequency may be set too low; try setting it higher to match the characteris-
tics of your other speakers (see Speaker Setting on page 113 ).
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 113 ).
Check that the LFE channel is not set to OFF, or to a very quiet setting (see Setting the
Audio options on page 88 ).
Check the speaker level settings (see Channel Level on page 114 ).
No sound from one speaker.
Check the speaker connection (see Connecting the speakers on page 25 ).
Check the speaker level settings (see Channel Level on page 114 ).
Check that the speaker hasn’t been set to NO (see Speaker Setting on page 113 ).
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 Enjoying various
types of playback using the listening modes on page 73 ).
No digital sound is output.
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 61 ).
Check the digital output settings on the source component.
SC-LX89 only:
No sound is produced even if
MULTI CH IN is selected.
When 5.2ch F+Surr Bi-Amp, 5.2ch F+C Bi-Amp or 5.2ch C+Surr Bi-Amp is selected in
the Speaker System settings, no sound is produced even when MULTI CH IN is selected.
Other audio problems
Symptom Remedy
Speaker switching sound (clicking
sound) is heard from receiver during
playback.
Since ECO MODE 1 and ECO MODE 2 reduce the power consumption, the speakers
are switched in function of the number of input channels. Because of this, a speaker
switching sound (clicking sound) may be produced when the number of input channels
is switched. If this bothers you, switch to a different listening mode.
Depending on the listening mode, the top middle and front height speakers may switch
automatically in function of changes in the input audio. A speaker switching sound
(clicking sound) will be heard from the receiver at this time. If this sound bothers you, we
recommend to change the speaker terminal option (see Switching the speaker terminals
on page 92 ).
Broadcast stations cannot be
selected automatically, or there is
considerable noise in radio broad-
casts.
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 43 ).
Adjust the position and direction of the AM antenna.
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.
Subwoofer output is very low.
To route more signal to the subwoofer, set it to PLUS or set the front speakers to SMALL
(see Speaker Setting on page 113 ).
Everything seems to be set up cor-
rectly, but the playback sound is odd.
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 Con-
necting the speakers on page 25 ).
The Phase Control feature doesn’t
seem to have an audible effect.
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 sub-
woofer, 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 114 ).
Full Band Phase Control cannot be
selected.
Perform Full Auto MCACC measurements (see Automatically conducting optimum
sound tuning (Full Auto MCACC) on page 59 ). Full Band Phase Control automatically
turns on once measurements are completed.
Can’t select some Input functions
by the INPUT SELECTOR on the
front panel or the ALL button on the
remote control.
Check the Input Skip settings in the Input Setup menu (see The Input Setup menu on
page 61 ).
Check the HDMI Input assignment in the Input Setup menu then try OFF (see The Input
Setup menu on page 61 ).
There seems to be a time lag
between the speakers and the output
of the subwoofer.
See Automatically conducting optimum sound tuning (Full Auto MCACC) on page 59
to set up your system again using MCACC (this will automatically compensate for a delay
in the subwoofer output).
The maximum volume available
(shown in the front panel display) is
lower than the +12dB maximum.
Check that the Volume Limit is set to OFF (see Volume Setup on page 115 ).
The channel level setting may be over 0.0dB.
