Symptom Remedy
No sound from front height or front
wide speakers. Check that the front height or front wide speakers are set to LARGE or SMALL, and the
surround speakers are not set to NO (see
Speaker Setting on page 89 ).
When Speaker System is set to Normal(SB/FH) or Normal(SB/FW) and SP: SB ON is
selected with the OUT P. button, no sound will be output from the front height or front
wide speakers. Select SP: SB/FH ON, SP: SB/FW ON, SP: FH ON or SP: FW ON (see
Switching the speaker terminals on page 71 ).
Check the speaker connections (see Connecting the speakers on page 20 ).
No sound from subwoofer. 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 89 ).
The crossover frequency may be set too low; try setting it higher to match the characteris-
tics of your other speakers (see
Speaker Setting on page 89 ).
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 89 ).
Check that the LFE channel is not set to OFF, or to a very quiet setting (see Setting the
Audio options on page 67 ).
Check the speaker level settings (see Channel Level on page 90 ).
No sound from one speaker. Check the speaker connection (see Connecting the speakers on page 20 ).
Check the speaker level settings (see Channel Level on page 90 ).
Check that the speaker hasn’t been set to NO (see Speaker Setting on page 89 ).
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 52 ).
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
54 ).
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 39 ).
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 out-
put 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.
If the source component has a digital volume control, make sure this is not turned down.
No sound when using the
HOME MENU. If the HDMI input function is selected, sound is muted until exiting the HOME MENU.
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 71 ).
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 29 ).
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 54 ).
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 89 ).
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 20 ).
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 90 ).
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.
Can’t select some Input functions
by the INPUT SELECTOR on the
front panel or the ALL button on the
remote control. Check the Input Skip settings in the Input Setup menu (see The Input Setup menu on
page 39 ).
Check the HDMI Input assignment in the Input Setup menu then try OFF (see The Input
Setup menu on page 39 ).
There seems to be a time lag
between the speakers and the output
of the subwoofer. See Automatically conducting optimum sound tuning (Full Auto MCACC) on page 37
to set up your system again using MCACC (this will automatically compensate for a delay
in the subwoofer output).
The maximum volume available
(shown in the front panel display) is
lower than the +12dB maximum. Check that the Volume Limit is set to OFF (see Volume Setup on page 93 ).
The channel level setting may be over 0.0dB.
Certain listening modes or
HOME MENU items cannot be
selected. When Operation Mode is set to Basic, the Pioneer-recommended settings are made and
not all of the functions can be used. To use all of the functions without restrictions, set
Operation Mode to Expert (see
Operation Mode Setup on page 40 ).
Some functions cannot be selected, depending on the input signal and listening mode.
