Other audio problems
No sound from surround back 
speakers.
• Check that the surround back speakers are set to
LARGE or SMALL (see Speaker Setting on page 40).
• Make sure surround back processing is set to
SBch ON (see Using surround back channel processing on
page 30).
• If the source is Dolby Surround EX or DTS-ES with no flag to indicate 6.1 compatibility, then with surround 
back processing set to 
SBch Auto, there will be no sound from the surround back speakers. In this case,
set to
SBch ON (see Using surround back channel processing on page 30).
• If the source does not have 6.1 playback channels, make sure that surround back processing is set to
SBch
ON and a surround mode is selected (see Listening in surround sound on page 27).
• Check the speaker connections (see 
Connecting the speakers on page 18). If only one surround back
speaker is connected, make sure it’s connected to the left channel speaker terminal.
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 40).
• 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 40)
• 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 40).
• Check the speaker level settings (see
Channel Level on page 41).
No sound from one speaker.
• Check the speaker connection (see
Connecting the speakers on page 18).
• Check the speaker level settings (see
Channel Level on page 41).
• Check that the speaker hasn’t been set to
NO (see Speaker Setting on page 40).
• 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 27).
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 30).
• Make sure that the digital input is assigned correctly for the input jack the component is connected to 
(see 
The Input Assign menu on page 55).
• 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 sound is muted in the sub zone (
ZONE 2), it will be restored after exiting the System Setup menu.

Broadcast stations cannot be 
selected automatically, or there is 
considerable noise in radio 
broadcasts.
For FM broadcasts
• 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 21).
For AM broadcasts
• Adjust the position and direction of the AM antenna.
• Use an outdoor antenna for better reception (see page 21).
• 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.
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 48).
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 30).
