Symptom Remedy
The Auto MCACC Setup
continually shows an error. • 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 47). If the noise level cannot be kept low
enough, you will have to set up the surround sound manually (page 121).
• 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.
– 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.
– 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.
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 121, and use the ALL (Keep
SP System) option for the Auto MCACC menu in Automatic MCACC (Expert) on page 107 if this is a
recurring problem.
SC-LX82 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 setting up for surround sound (Auto MCACC & Full Band Phase Control) on page 45).
• 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.
Can’t adjust the Fine Speaker
Distance setting (page 111)
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
