Unpacking the subwoofer
In this operating manual, the following
signs and symbols are used:
The exclamation point within an
equilateral triangle is intended to
alert the user to the presence of
important operating and maintenance
(servicing) instructions in the literature
accompanying the product.
Indicates (in combination with a safety
sign) a potentially hazardous situation
which, if not avoided, could result in
minor or moderate injury or damage to
equipment.
1. Unpack the subwoofer on a clean,
even and soft area; oor carpeting is
very suitable.
2. The packaging should be opened
from the top (1). Remove all
accessories that come packed with
the subwoof er (such as AC power
cord and grille). Do not remove the
top part of the protective material.
3. With the protective material still in
place but with accessories removed,
carefully tilt the packaging on its side
(1) and tilt again to turn it upside-
down (2). Ensure that no part of the
top-cover is obstructing the opening
at the top.
4. The outer packaging can now be
lifted away from the subwoofer itself
(3). Remove the protective material
that now is on top.
5. Open the bag and remove such from
around the base of the subwoofer.
6. Again, carefully tilt the subwoofer
on its side and again to turn it onto
its feet. Note that the top part of the
protective material will now come off
easily so ensure that the subwoofer
doesn’t drop or slide away in the
process.
Note
Be careful when mounting the grille not to touch the cone of the loudspeaker itself.
Check that the contents are complete:
• Subwoofer: The factory-set power
requirements (refer to label on rear
of subwoofer) should correspond for
the region where the subwoofer was
purchased. Refer also to “Important
safety instructions” on page 1.
• Front bafe grille.
• AC mains lead. The supplied
lead should be suitable for the
region where the subwoofer was
purchased.
• This owner’s manual.
Grille
The subwoofer can be operated without
the grille. However, it is recommended
that the grille is mounted during
normal use to help prevent accidental
damage or dirt settling on the cone of
the loudspeaker. With subwoofers, the
inuence of the grille on the sound is
virtually negligible.
To remove the grille:
Gently pull the grille at all corners.
To t the grille:
Line up the studs with the
corresponding front bafe holes.
Gently push the grille in at all
corners.
