Symptom Remedy
The Auto MCACC Setup
continually shows an error.
• The ambient noise level may be too high. Keep the noise level in the r oom as low as possible (see
also Problems when using the Auto MCACC Setup on page 41). If the noise level cannot be kept low
enough, you will have to set up the surround sound manually (page 85).
• When using only one surround back speaker, connect it to the SURROUND BACK L (Single)
terminals.
• To use a 5.1-channel speaker set, use the surround speakers for the surround channel, not the
surround back channel.
• Make sure there are no obstacles between the speakers and the microphone.
• If Reverse Phase is displayed, try the following:
– The speaker’s wiring (+ and –) may be inverted. Check the speaker connections.
– Depending on the type of speakers and their installation conditions, Reverse Phase may be
displayed even if the speakers are properly connected. If this happens, select
GO NEXT and continue.
– If the speaker is not pointed to the microphone (listening position) or when using speakers that
affect the phase (dipole speakers, reflective speakers, etc.), it may not be possible to properly identify
the polarity.
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 86, and use the ALL (Keep
SP System) option for the Auto MCACC menu in Automatic MCACC (Expert) on page 73 if this is a
recurring problem.
Can’t adjust the Fine Speaker
Distance setting (page 76)
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.
• 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 75 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.
