Remedy
• The ambient noise level may be too high. Keep the noise level in the room as low as possible (see
also Problems when using the Auto MCACC Setup on page 37). If the noise level cannot be kept low
enough, you will have to set up the surround sound manually (page 78).
• 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.
• 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 (bass reproduction capabilities of the speakers, room size,
speaker placement, etc.) this may occur in some cases. Change the speaker setting manually in
Speaker Setting on page 79, and use the ALL (Keep SP System) option for the Auto MCACC menu
in Automatic MCACC (Expert) on page 69 if this is a recurring problem.
• Check that the speakers are all in phase (make sure the positive (+) and negative (–) terminals are
matched up properly).
• With the receiver in standby, press  STANDBY/ON for about 10 seconds while holding down
SPEAKERS to disable the key lock.
• 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.
• Make sure the blue  STANDBY/ON light has gone out before unplugging.
Remedy
• 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.
• 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.
• 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.
Remedy
• Press DIMMER repeatedly to select a different brightness.
• Check the digital connections and make sure that the digital inputs are assigned correctly (see The
Input Setup menu on page 37).
• If the multichannel analog inputs are selected, select a different input function.
