Setup: Sound: Speaker Groups: PRESETNAME: Advanced Settings
Selecting this menu brings you to the
Advanced Settings menu for the current
Speaker Group.
Setup: Sound: Speaker Groups: PRESETNAME: Speaker Roles
This menu allows you to enable the
loudspeakers that are used in the
current Speaker Group. In addition, you
can set the desired channel allocation
for each loudspeaker (or Power Link
output channel).
When configuring a 5.1-channel
surround system, note that the rear
loudspeakers should be set as Left
Surround and Right Surround (not Left
Back and Right Back).
Note that there are no restrictions on
how many copies of a given speaker role
that may be distributed in a Speaker
Group. For example, if you have 10
loudspeakers connected to the
television, it is allowed (although
perhaps not advisable…) to have 10 Left
Surrounds and nothing else.
Two of the Speaker Roles are not
traditional speaker roles: these are the
Mix Left and Mix Right options. These
are outputs from a two-channel
‘downmix’ of the input signal, and are
intended for users wishing to send a
signal to a second room. These two
channels will be created from all
incoming channels. If your input signal is
from a two-channel stereo source, then
the Mix Left and Mix Right outputs will
match the Left and Right inputs
respectively. However, if you have a 5.1
or 7.1 input from a DVD or Blu-ray disc,
then these channels will be combined
into the two-channel Mix Left and Mix
Right output. Note that this downmixing
algorithm is the same one that is used
for the television’s headphone output.
If you have only two loudspeakers in
your main configuration, it is
recommendable that you assign the Left
Front and Right Front (instead of the
Mix Left and Mix Right) roles to those
loudspeakers and allow the TrueImage
processing to do the automatic
downmixing.
The positions corresponding to the
various Speaker Roles are shown in
Figures 7 and 8 on page 12.
Options: Centre Front / Left Front / Right

Rear / Sub Left / Sub Right / Mix
Left / Mix Right.
Setup: Sound: Speaker Groups: PRESETNAME: Speaker Distances
This setting is used to ensure that the
times of arrival of the loudspeakers’
signals at the listening position are
matched, despite them being placed at
different distances from the listening
position. The value displayed on the
menu should be the distance from the
listening position to each loudspeaker.
The result of this alignment is that all
loudspeakers’ signals are individually
delayed to match the time of arrival of
the sound from the most distant
loudspeaker.
Note that, since the Listening Position
can be different for different Speaker
Groups, these distances may not
necessarily be the same from Speaker
Group to Speaker Group. In addition,
the small differences in latency between
various Bang & Olufsen loudspeakers,
connected either wirelessly or with
Power Link cables, are automatically
compensated for internally in the
system.
