FAQ

Symptoms Remedies

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 101).

Check the speaker connections (see Connecting the speakers on page 22).

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 101).

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 101).

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 101).

Check that the LFE channel is not set to OFF, or to a very quiet setting (see Setting the

Audio options on page 76).

Check the speaker level settings (see Channel Level on page 101).

No sound from the speakers.

Check the AMP setting. Set it to ON when you want to output sound from all the speakers

(Setting the Audio options on page 76).

No sound from one speaker.

Check the speaker connection (see Connecting the speakers on page 22).

Check the speaker level settings (see Channel Level on page 101).

Check that the speaker hasn’t been set to NO (see Speaker Setting on page 101).

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 60).

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

62).

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 47).

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.

SC-LX87 only:

No sound is produced even if

MULTI CH IN is selected.

When 5.1ch F+Surr Bi-Amp, 5.1ch F+C Bi-Amp or 5.1ch C+Surr Bi-Amp is selected in

the Speaker System settings (when the center or surround speakers are bi-amped), no

sound is produced even when MULTI CH IN is selected.

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

Symptoms Remedies

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 80).

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 37).

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 62).

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 101).

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 Connect-

ing the speakers on page 22).

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 102).

Full Band Phase Control cannot be

selected.

Perform Full Auto MCACC measurements (see Automatically conducting optimum sound

tuning (Full Auto MCACC) on page 46). 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.

Can’t select some Input functions by

the INPUT SELECTOR on the front

panel or the INPUT SELECT button

on the remote control.

Check the Input Skip settings in the Input Setup menu (see The Input Setup menu on

page 47).

Check the HDMI Input assignment in the Input Setup menu then try OFF (see The Input

Setup menu on page 47).

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 46 to

set up your system again using MCACC (this will automatically compensate for a delay in

the subwoofer output).
