• Set the front speakers with their front surfaces as
flush with the TV or monitor screen as possible. Set
the center speaker between the front left and right
speakers and no further from the listening position
than the front speakers.
• Consult the owner's manual for your subwoofer for
advice on placing the subwoofer within the listening
room.
• If the surround speakers are direct-radiating
(monopolar) then place them slightly behind and at
an angle to the listening position and parallel to the
walls at a position 60 to 90 centimeters (2 to 3 feet)
above ear level at the prime listening position.
• Connect the surround speakers to the surround
speaker A terminals on the AVC-A11XV and set
settings on the setup menu to "A". (This is the
factory default setting ( page 59).)
• The surround speakers can be switched freely
during playback with the surround parameter
adjustment ( page 21).

The AVC-A11XV is equipped with a digital signal
processing circuit that lets you play program sources
in the surround mode to achieve the same sense of
presence as in a movie theater.
[1] Dolby Surround
q Dolby Digital
Dolby Digital is the multi-channel digital signal
format developed by Dolby Laboratories.
Dolby Digital consists of up to "5.1" channels -
front left, front right, center, surround left,
surround right, and an additional channel
exclusively reserved for additional deep bass
sound effects (the Low Frequency Effects – LFE –
channel, also called the ".1" channel, containing
bass frequencies of up to 120 Hz).
Unlike the analog Dolby Pro Logic format, Dolby
Digital's main channels can all contain full range
sound information, from the lowest bass, up to
the highest frequencies – 22 kHz. The signals
within each channel are distinct from the others,
allowing pinpoint sound imaging, and Dolby Digital
offers tremendous dynamic range from the most
powerful sound effects to the quietest, softest
sounds, free from noise and distortion.

between "bitstream" and "(convert to) PCM".
When playing in Dolby Digital surround on the
AVC-A11XV, switch the DVD player's output
mode to "bitstream". In some cases players are
equipped with both "bitstream + PCM" and
"PCM only" digital outputs. In this case connect
the "bitstream + PCM" terminals to the AVC-
A11XV.

• Dolby Pro Logic is a new multi-channel playback
format developed by Dolby Laboratories using
feedback logic steering technology and offering
improvements over conventional Dolby Pro Logic
circuits.
II
• Dolby Pro Logic can be used to decode not only
sources recorded in Dolby Surround (
regular stereo sources into five channels (front left,
front right, center, surround left and surround right)
to achieve surround sound.
• Whereas with conventional Dolby Pro Logic the
surround channel playback frequency band was

limited, Dolby Pro Logic offers a wider band range
(20 Hz to 20 kHz or greater). In addition, the surround
channels were monaural (the surround left and right
channels were the same) with previous Dolby Pro
II
Logic, but Dolby Pro Logic they are played as
stereo signals.
• Various parameters can be set according to the type
of source and the contents, so it is possible to
achieve optimum decoding ( page 27).
