LARGE
or
SMALL
(see
Speaker Setting
on page 46).
• Make sure surround back processing is set to
SBch ON
(see
Using surround back channel processing
on
page 29).
• 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

SBch
ON
and a surround mode is selected (see
Listening in surround sound
on page 26).
• Check the speaker connections (see
Connecting the speakers
on page 17). If only one surround back
speaker is connected, make sure it’s connected to the left channel speaker terminal.

• If your subwoofer has a sleep function, make sure it is switched off.
• Make sure that the Subwoofer setting is

Speaker Setting
on page 46).
• 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 46).

SMALL
/ Subwoofer:
YES
, or Front:

• 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

on page 26).
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 29).
• Make sure that the digital input is assigned correctly for the input jack the component is connected to

The Input Setup menu
on page 56).
• 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.

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 20).
For AM broadcasts
• Adjust the position and direction of the AM antenna.
• Use an outdoor antenna for better reception (see page 20).
• 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 52).
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 29).
