13 FAQ Symptom Remedy No sound from surround back speakers. Check that the surround back speakers are set to LARGE or SMALL, and the surround speakers are not set to NO (see Speaker Setting on page 105 ). Check the speaker connections (see Connecting the speakers on page 25 ). If only one surround back speaker is connected, make sure it's connected to the left channel speaker terminal. When Dolby Surround is selected, audio is not output from the surround back speaker when it is the only one connected (set). No sound from front height or front Check that the front height or front wide speakers are set to LARGE or SMALL, and the wide speakers. surround speakers are not set to NO (see Speaker Setting on page 105 ). When Speaker System is set to 7.2.2ch TMd/FW and SP: TMd ON is selected with the OUT P. button, no sound will be output from the front wide speakers. Select SP: FW ON or SP: TMd/FW ON (see Switching the speaker terminals on page 84 ). When Speaker System is set to 7.2.2ch TMd/FH and SP: TMd ON is selected with the OUT P. button, no sound will be output from the front height speakers.

Check that the subwoofer is connected properly, switched on and the volume turned up. If your subwoofer has a sleep function, make sure it is switched off. Make sure that the Subwoofer setting is YES or PLUS (see Speaker Setting on page 105 ). The crossover frequency may be set too low; try setting it higher to match the characteristics of your other speakers (see Speaker Setting on page 105 ). If there is very little low frequency information in the source material, change your speaker settings to Front: SMALL / Subwoofer: YES, or Front: LARGE / Subwoofer: PLUS (see Speaker Setting on page 105 ). Check that the LFE channel is not set to OFF, or to a very quiet setting (see Setting the Audio options on page 80) . Check the speaker level settings (see Channel Level on page 106 ).

Check that the speaker hasn't been set to NO (see Speaker Setting on page 105 ). The channel may not be recorded in the source. By using one of the advanced effect listening modes, you may be able to create the missing channel (see Enjoying various types of playback using the listening modes on page 64 ). Sound is produced from analog components, but not from digital ones (DVD, LD, CD, etc.). Check that the input signal type is set to DIGITAL (see Choosing the input signal on page 66 ). Make sure that the digital input is assigned correctly for the input jack the component is connected to (see The Input Setup menu on page 52 ). Check the digital output settings on the source component. If the source component has a digital volume control, make sure this is not turned down. No sound is output or a noise is output when Dolby Digital/DTS software is played back. Check that your BD or DVD player is compatible with Dolby Digital/DTS discs. Check the digital output settings or the HDMI audio output settings of your BD or DVD player. Make sure that the DTS signal output is set to On.

Other audio problems
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 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
Switching the
speaker terminals
on
page 84
).
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
page 40
).
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.
Noise is output when scanning a
DTS CD.
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.
When playing a DTS format LD there
is audible noise on the soundtrack.
Make sure that the input signal type is set to
DIGITAL
(see
Choosing the input signal
on
page 66
).
Can’t record audio.
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.
Subwoofer output is very low.
To route more signal to the subwoofer, set it to
PLUS
or set the front speakers to
SMALL
(see
Speaker Setting
on
page 105
).
Everything seems to be set up cor-
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
Con-
necting the speakers
on
page 25
).
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
Speaker Distance
on
page 106
).
Full Band Phase Control cannot be
selected.
Perform Full Auto MCACC measurements (see
Automatically conducting optimum
sound tuning (Full Auto MCACC)
on
page 51
). Full Band Phase Control automatically
turns on once measurements are completed.
Noise or hum can be heard even
when there is no sound being input.
Check that personal computers or other digital components connected to the same
power source are not causing interference.
