Remedy
Since ECO MODE 1 and ECO MODE 2 reduce the power consumption, the speakers
are switched in function of the number of input channels. Because of this, a speaker
switching sound (clicking sound) may be produced when the number of input channels
is switched. If this bothers you, switch to a different listening mode.
Depending on the listening mode, the top middle 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 to change the speaker terminal option (see
terminals on page 75 ).
Fully extend the FM wire antenna, adjust the position for best reception and secure to a
wall, etc.
Use an outdoor antenna for better reception (see page 33
Adjust the position and direction of the AM antenna.
Noise may be caused by interference from other equipment, such as a fluorescent light,
motor, etc. Switch off or move the other equipment, or move the AM antenna.
To route more signal to the subwoofer, set it to PLUS or set the front speakers to SMALL
(see Speaker Setting on page 94 ).
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
necting 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 sub-
woofer, 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
on page 95 ).
Check the Input Skip settings in the Input Setup menu (see
page 48 ).
Check the HDMI Input assignment in the Input Setup menu then try OFF (see
Setup menu on page 48 ).
See Automatically conducting optimum sound tuning (Full Auto MCACC)
to set up your system again using MCACC (this will automatically compensate for a delay
in the subwoofer output).
Check that the Volume Limit is set to OFF (see Volume Setup
The channel level setting may be over 0.0dB.
Some functions cannot be selected, depending on the input signal and listening mode.
The temperature within the unit has exceeded the allowable value. Try moving the unit for
better ventilation (see Installing the receiver on page 11 ).
Set the Channel Level setting to ALL, then adjust the volume of the respective input
sources (see Input Volume Absorber on page 76 ).
When HDZONE is selected in Speaker System and also the same HDMI input is selected
for both the main zone and HDZONE, 2-channel PCM audio sources are output from the
main zone as well. To output multi-channel audio sources, set HDZONE to OFF or change
the HDZONE input.
