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 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 to change the speaker terminal option (see
speaker 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 32
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.
This is not a malfunction of the receiver. The scan function of your player alters the digital
information, making it unreadable, resulting in noise being output. Lower the volume
when scanning.
Make sure that the input signal type is set to DIGITAL (see
page 58 ).
You can only make a digital recording from a digital source, and an analog recording
from an analog source.
For digital sources, make sure that what you're recording isn't copy protected.
To route more signal to the subwoofer, set it to PLUS or set the front speakers to SMALL
(see Speaker Setting on page 93 ).
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 22 ).
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 94 ).
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 (see
page 44 ).
Check the HDMI Input assignment in the Input Setup menu then try OFF (see
Setup menu on page 44 ).
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.
