Symptom
Remedy
Speaker switching sound (clicking
sound) is heard from receiver during
playback.
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 front height 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
Switching the speaker terminals
Broadcast stations cannot be
selected automatically, or there is
considerable noise in radio broad-
casts.
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
).
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.
Subwoofer output is very low.
To route more signal to the subwoofer, set it to
PLUS
or set the front speakers to
SMALL

rectly, but the playback sound is odd.
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
on

The Phase Control feature doesn’t
seem to have an audible effect.
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
Full Band Phase Control cannot be
selected.
Perform Full Auto MCACC measurements (see
