Adapt the loudspeakers to your room
The loudspeakers may be placed
almost anywhere in you room.
However, the most natural sound
is obtained if they are set up as
explained on these pages.
The Acoustic Lens Technology
system ensures better balance in
the high tone frequencies coming
directly from each loudspeaker,
and the sound reflected by the
room. The system also ensures
correct tonal balance in the whole
area in front of the loudspeaker.
The FREE–WALL–CORNER switch
When a loudspeaker is placed in a corner or
close to a wall, the bass level is boosted
compared to the bass level from a loudspeaker
placed in a more free-standing position.
To remove this excessive bass boost, set the
switch marked FREE–WALL–CORNER to ensure
that the bass level suits the placement of the
loudspeaker. The appropriate switch setting
depends on the distance from the loudspeaker
to the walls and corners of the room.
Use the guidelines mentioned here, and the
illustration and the examples on the next page,
when deciding which of the three POSITION
switch setting to select – on each loudspeaker.
FREE
Use this setting if the loudspeaker is placed
more than 20 cm (8") from the wall, and no
closer to a corner than 65 cm (26") – shown by
the large light grey area in the illustration on
the next page.
WALL
Use this setting if the loudspeaker is placed less
than 20 cm (8") from the wall, and no closer
to a corner than 65 cm (26") – shown by the
grey areas along the walls in the illustration on
the next page.
CORNER
Use this setting if the loudspeaker is placed in
a corner – shown by the dark grey areas in the
illustration on the next page.
