Setup: Sound: Speaker Groups: PRESETNAME: Advanced Settings: Bass Management: Re-Direction
Levels: SPEAKERROLE
It is possible in the television to use any
loudspeaker to reproduce the LFE
channel and low-frequency content
from the bass management system. This
is done using the Bass Redirection.
Typically, in a bass-managed 5.1 or 7.1
system, the LFE and the bass
management output will be directed to
a single subwoofer. However, if you
desire, it is possible to send that
information to any loudspeakers in the
current Speaker Group by increasing the
Redirection Levels. Note that initial settings in this menu
are automatically chosen based on
information from the Speaker Types
menu and the Speaker Roles for the
current Speaker Group.
Setup: Sound: Speaker Groups: PRESETNAME: Advanced Settings: Bass Management: Re-Direction
Balance: SPEAKERROLE
As described above, the bass
management system in the television
produces two channels of low-frequency
content. The Bass Redirection Balance is
used to control the relative level of each
of these two channels in the signal sent
to each loudspeaker. Typically, if you are
using a single subwoofer, then the
Balance will be set to the middle
position (0), ensuring that both low-
frequency channels are present in the
subwoofer. However, if you have two
subwoofers and they are set to have
Speaker Roles of Sub Left and Sub Right,
then the left subwoofer will have a
Redirection Balance set to LEFT (-1) and
the right subwoofer to RIGHT (1). This
will ensure that the stereo information
from the bass management output is
maintained as a stereo signal in the
listening room.
Note that initial settings of this menu
are automatically chosen based on
information from the Speaker Roles for
the current Speaker Group.
Setup: Sound: Speaker Connections: SPEAKERTYPE
This menu is used to indicate the type or
model of loudspeaker connected to each
output of the television. All current
Bang & Olufsen loudspeakers are listed
in this menu, including some
discontinued models such as the BeoLab
1 and BeoLab Penta loudspeakers.
Two additional options are included in
this list.
– ‘Other’ is used to indicate a
loudspeaker that is not included in
the list of Bang & Olufsen
loudspeakers, for example, a
loudspeaker from a different
manufacturer. Note that, in this case,
the output will be volume-regulated.
– ‘Line’ is used to indicate that the
output signal is destined for the line
input of another amplifier with its
own volume control (for example, in a
second listening room). Note that the
output level of the Power Link output,
when in a ‘Line’ speaker role, is not
volume-regulated. Its output level is
calibrated to correspond to a -10 dBV
consumer line level with a 2 V rms
maximum output, and thus is
compatible with consumer-level
audio-video devices with a line input.
WARNING! If you have a BeoLab
loudspeaker connected to a Power Link
output and you set the Speaker Role for
that output to ‘Line’, the resulting
output will not be volume regulated and
therefore may produce very loud
outputs! Use this Speaker Role with
caution.
Note that the television automatically
enters settings in other menus (for
example, Bass Management Advanced
Settings) based on the information
entered in this menu.
Options: BeoLab / BeoVox / Line /
Other / None.
