Enjoying Surround Sound
You can take advantage of surround sound
simply by selecting one of the receiver’s pre-
programmed sound fields. They bring the
exciting and powerful sound of movie theaters
and concert halls into your home. You can also
customize the sound fields to obtain the sound
you want by changing the surround parameter.
To fully enjoy surround sound, you must
register the number and location of your
speakers. See “Multi channel surround setup”
starting from page 14 to set the speaker
parameters before enjoying surround sound.
Decoding the input audio
signal automatically
(Auto Format Direct)
Press A.F.D.
“A.F.D. AUTO” appears in the display.
This mode automatically detects the type of
audio signal being input (Dolby Digital, DTS,
or standard 2 channel stereo) and performs the
proper decoding if necessary. This mode
presents the sound as it was recorded/encoded,
without adding any effects (e.g. reverberation).
However, if there are no low frequency signals
(Dolby Digital LFE, etc.) it will generate a low
frequency signal for output to the sub woofer.
Enjoying stereo sound in
multi channel
(Dolby Pro Logic
II )
This function lets you specify the type of
decoding for 2 channel audio sources.
This receiver can reproduce 2 channel sound in
5 channels through Dolby Pro Logic II; or 4
channels through Dolby Pro Logic.
Press ;PL/PL II repeatedly to select
“DOLBY PL”, “PL II MOV” or “PL II MUS”.
The selected mode appears in the display.
x DOLBY PL (Dolby Pro Logic)
Performs the Pro Logic decoding. Software
with multi channel surround audio signals is
played back according to the way it was
recorded. Software with 2 channel audio
signals is decoded with Dolby Pro Logic to
create surround effects (4 channels).
x PL II MOV (Pro Logic II Movie)
Performs the Pro Logic II movie mode
decoding. This setting is ideal for the movies
encoded in Dolby Surround. Besides, this mode
can reproduce the sound in 5.1 channel when
watching the videos of old movies or in the
dubbed language.
x PL II MUS (Pro Logic II Music)
Performs the Pro Logic II music mode
decoding. This setting is ideal for normal stereo
sources such as CDs.
Tip
You can also use ;PLII on the receiver to select
“DOLBY PL”, “PLII MOV” or “PLII MUS”.
Note
Dolby Pro Logic and Dolby Pro Logic II decoding
does not function for DTS format signals.
