2.6.2.2. Surround Reproduction
2.6.2.4. Useful Combinations of
Surround Processing Modes
Surround sound can be reproduced with four choices:
In principle, "Decoder Matrix", "Surround Reproduc-
tion", and "Center Modes" are independent settings (all
"Decoder Matrix" settings can be used with all "Sur-
round Reproduction" and "Center Modes") but there
are some combinations that do not create "good"
sound. Useful combinations are
– REAR_SPEAKER:
If there are any surround speakers connected to the
system, this mode should be used. Useful loud-
speaker combinations are: (L, C, R, S) or (L, R, S).
– FRONT_SPEAKER:
If there is no surround speaker connected, this
mode can be used. Surround information is mixed to
left and right output but without creating the illusion
of a virtual speaker. It is similar to stereo but an
additional center speaker can be used. This mode
should be used with the adaptive decoder matrix
only. Useful loudspeaker combinations are: (L, C, R)
(Note: the surround output channel is muted).
Surround Reproduction and Center Modes
– REAR_SPEAKER:
This mode is used if surround speakers are avail-
able. Useful center modes are NORMAL, WIDE,
PHANTOM, and OFF.
– FRONT_SPEAKER:
This mode can be used if no surround speaker but a
center speaker is connected. Useful center modes
are NORMAL and WIDE.
– PANORAMA:
The surround information is mixed to left and right in
order to create the illusion of a virtual surround
speaker. Useful loudspeaker combinations are: (L,
C, R) or (L, R) (Note: the surround output channel is
muted).
– PANORAMA or 3D-PANORAMA:
No surround speaker used. Two (L and R) or three
(L, R, and C) loudspeakers can be used. Useful
center modes are NORMAL, WIDE, PHANTOM,
and OFF.
– 3D-PANORAMA:
Like PANORAMA with improved effect. This algo-
rithm has been approved by the Dolby Laboratories
for compliance with the "Virtual Dolby Surround"
technology. Useful loudspeaker combinations are:
(L, C, R) or (L, R) (Note: the surround output chan-
nel is muted).
Center Modes and Decoder Matrix
– PHANTOM:
Should only be used together with ADAPTIVE
Decoder Matrix.
– NORMAL and WIDE:
Can be used together with any Surround Decoder
Matrix.
2.6.2.3. Center Modes
Four center modes are supported:
– OFF:
In special cases, this mode can be used together
with the PASSIVE and EFFECT Decoder Matrix (no
center speaker connected).
– NORMAL:
small center speaker connected, L and R speakers
have better bass capability.
– WIDE:
L,R, and C speakers all have good bass capability.
– PHANTOM:
No center speaker used. Center signal is distributed
to L and R (Note: the center output channel C is
muted).
– OFF:
No center speaker used. Center signal C is dis-
carded (Note: the center output channel C is
muted).
