Professional Calibration EQ graphical output
After using the Auto MCACC
Setup, the speaker size
setting is incorrect.
• There may have been some low frequency noise in the room from an air-
conditioner, motor, etc. Switch off all other appliances in the room and use
Auto MCACC Setup again.
• Depending on a number of factors (room size, speaker placement, etc.) this
may occur in some cases. Change the speaker setting manually in Speaker
Setting on page 95, and use the ALL (Keep SP System) option for the Auto
MCACC menu in Automatic MCACC (Expert) on page 78 if this is a recurring
problem.
Can’t adjust the Fine Speaker
Distance setting (page 83)
properly.
• Check that the speakers are all in phase (make sure the positive (+) and
negative (–) terminals are matched up properly).
The display shows KEY LOCK
ON when you try to make
settings.
• With the receiver in standby, press STANDBY/ON 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.
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 82 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 this into account by the filters dedicated to overall system calibration.
Lower frequency 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.
