Professional Calibration EQ graphical output
Display
Can’t adjust the Fine Speaker
Distance setting (page 102)
properly.
• Check that the speakers are all in phase (make sure the positive (+) and negative (–) terminals are
matched up properly).
SC-LX83 only: Gauge (value)
does not increase with the
Precision Distance
adjustment.
• Check that the speakers are all in phase (make sure the positive (+) and negative (–) terminals are
matched up properly).
• Perform the Full Auto MCACC procedure before the Precision Distance adjustment (see
Automatically conducting optimum sound tuning (Full Auto MCACC) on page 43).
• Place the microphone accurately in the same position as when the Full Auto MCACC procedure
was performed.
• Do not move the speaker used as the reference point. Also, adjust in order, starting from the front
right speaker.
• When adjusting the speaker positions, do not move the speakers much; only move them about 2
cm towards or away from the microphone.
• If you forget exactly where the microphone should be positioned or if there are problems after the
procedure has been performed repeatedly, re-calibrate the distance using the Full Auto MCACC
procedure, then without moving the microphone redo the Precision Distance adjustment.
The display shows
KEY LOCK ON
when you try to make settings.
• With the receiver in standby, press STANDBY/ON for about 10 seconds while holding down
SPEAKERS to disable the key lock.
Most recent settings have been
erased.
• The power cord was disconnected from the wall while adjusting this setting.
• Settings are only stored if all the zones are turned off. Turn off all the zones before unplugging the
power cord.
The various system settings are
not stored.
• Make sure the blue STANDBY/ON light has gone out before unplugging.
Symptom Remedy
The EQ response displayed in
the graphical output following
calibration does not appear
entirely flat.
• There are cases where the graph does not appear flat (even when selecting ALL CH ADJ in the Auto
MCACC Setup) due to adjustments made to compensate for room characteristics to achieve optimal
sound.
• Areas of the graph may appear identical (before and after) when there is little or no adjustment
needed.
• The graph may appear to have shifted vertically when comparing before and after measurements.
EQ adjustments made using
the Manual MCACC setup on
page 101 do not appear to
change the graphical output.
• Despite level adjustments being made, the filters used for analysis may not display these
adjustments in the graphical output. However, these adjustments are taken into account by the
filters dedicated to overall system calibration.
Lower freq
uency response
curves do not seem to have
been calibrated for SMALL
speakers.
• Low frequencies used in bass management (the subwoofer channel) will not change for speakers
that have been specified as SMALL in the configuration, or do not output these frequencies.
• Calibration is performed, but due to your speakers’ low frequency limitations, no measurable
sound is output for display.
Symptom Remedy
The display is dark or off. • Press DIMMER repeatedly to select a different brightness.
You can’t get DIGITAL to
display when using SIGNAL
SEL.
• Check the digital connections and make sure that the digital inputs are assigned correctly (see The
Input Setup menu on page 45).
• If the multichannel analog inputs are selected, select a different input function.
2 DIGITAL or DTS does not
light when playing Dolby/DTS
software.
• These indicators do not light if playback is paused.
• Check the playback (especially the digital output) settings of the source component.
When playing Dolby Digital or
DTS sources, the receiver’s
format indicators do not light.
• Check that the player is connected using a digital connection.
• Make sure that the receiver is set to AUTO or DIGITAL (see Choosing the input signal on page 58).
• Check that the player isn’t set up so that Dolby Digital and DTS sources are converted to PCM.
• Ensure that if there are several audio tracks on the disc, the Dolby Digital or DTS is selected.
