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 40). If the noise level cannot be kept low enough, you will have to set up
the surround sound manually (page 93).
• 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 (room size, speaker placement, etc.) this
may occur in some cases. Change the speaker setting manually in Speaker
Setting on page 94, and use the ALL (Keep SP System) option for the Auto
MCACC menu in Automatic MCACC (Expert) on page 77 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 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.
