Remedy
• The speakers may be out of phase. Check that the positive/negative speaker terminals on the
receiver are matched with the corresponding terminals on the speakers (see Connecting the
speakers on page 23).
• If applicable, check that the lowpass filter switch on your subwoofer is off, or the lowpass cutoff is
set to the highest frequency setting. If there is a PHASE setting on your subwoofer, set it to 0º (or
depending on the subwoofer, the setting where you think it has the best overall effect on the sound).
• Make sure the speaker distance setting is correct for all speakers (see Speaker Distance on
page 111).
• Perform Full Auto MCACC measurements (see Automatically conducting optimum sound tuning
(Full Auto MCACC) on page 43). Full Band Phase Control automatically turns on once measurements
are completed.
• Check that personal computers or other digital components connected to the same power source
are not causing interference.
• Check the Input Skip settings in the Input Setup menu.
• Check the HDMI Input assignment in the Input Setup menu then try OFF.
• See Automatically conducting optimum sound tuning (Full Auto MCACC) on page 43 to set up your
system again using MCACC (this will automatically compensate for a delay in the subwoofer output).
• Depending on the listening mode, the front height (or front wide) and surround back speakers may
switch automatically in function of changes in the input audio. A speaker switching sound (clicking
sound) will be heard from the receiver at this time. If this sound bothers you, we recommend
changing the listening mode (see Listening in surround sound on page 55).
• Check that the Volume Limit is set to OFF (see Volume Setup on page 114).
• The channel level setting may be over 0dB.
Remedy
• Check that no object that emits electromagnetic waves in the 2.4 GHz band (microwave
oven, wireless LAN device or Bluetooth wireless technology apparatus) is near the unit. If
such an object is near the unit, set the unit far from it. Or, stop using the object emitting the
electromagnetic waves.
• Check that the Bluetooth wireless technology device is not too far from the unit and that
obstructions are not set between the Bluetooth wireless technology device and the unit. Set
the Bluetooth wireless technology device and the unit so that the distance between them is
less than about 10 m and no obstructions exist between them.
• Check that the Bluetooth ADAPTER and the ADAPTER PORT of the unit are correctly
connected.
• The Bluetooth wireless technology device may not be set to the communication mode
supporting the Bluetooth wireless technology. Check the setting of the Bluetooth wireless
technology device.
• Check that pairing is correct. The pairing setting was deleted from this unit or the Bluetooth
wireless technology device. Reset the pairing.
• Check that the profile is correct. Use a Bluetooth wireless technology device that supports
A2DP profile and AVRCP profile.
