Other audio problems
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 52).
• 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 52).
• 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 52).
• Check that the LFE channel is not set to OFF, or a very quiet setting (see Setting the Audio options on
page 99).
• Check the speaker level settings (see
Channel Level on page 53).
• Check that the subwoofer is only connected to the PREOUT SUBWOOFER2 terminal. When only
connecting one subwoofer, connect it to the PREOUT SUBWOOFER1 terminal.
No sound from one speaker. • Check the speaker connection (see Connecting the speakers on page 28).
• Check the speaker level settings (see Channel Level on page 53).
• Check that the speaker hasn’t been set to NO (see Speaker Setting on page 52).
• The channel may not be recorded in the source. By using one of the advanced effect listening mode, you
may be able to create the missing channel (see
Listening in surround sound on page 34).
Sound is produced from analog
components, but not from digital
ones (DVD, LD, CD-ROM etc.). • Check that the input signal type is set to DIGITAL (see Choosing the input signal on page 37).
• 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 94).
• 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.
• Make sure that the multichannel analog inputs are not selected. Select any other input source.
No sound is output or a noise is
output when Dolby Digital/DTS
software is played back. • Check that your DVD player is compatible with Dolby Digital/DTS discs.
• Check the digital output settings of your 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 System
Setup or Status menu. • If the HDMI input source is selected, sound is muted until exiting either menu.
• If sound is muted in the sub zone (
ZONE 2), it will be restored after exiting the System Setup menu.
Symptom Remedy
Symptom Remedy
A multichannel DVD source
appears to be downmixed to 2
channels during playback. • Make sure that the multichannel analog inputs are selected (see Selecting the multichannel analog inputs
on page 60).
Noise is output when scanning a
DTS CD. • This is not a malfunction of the amplifier. 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 37).
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.
• Check that the
OUT jacks are properly connected to the recorders input jacks (see Connecting analog
audio sources on page 26).
Recorded audio is different from
the current source, or inaudible. • The RECOUT source is set to an input source other than the source you’re listening to. Select RECOUT
SOURCE to record the current input source (see Playing a different source when recording on page 102).
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 52).
Everything seems to be set up
correctly, but the playback sound
is odd. • The speakers may be out of phase. Check that the positive/negative speaker terminals on the amplifier are
matched with the corresponding terminals on the speakers (see
Connecting the speakers on page 28).
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 subwoofer, 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 54).
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.
