functioning and safety of the items, these must be withdrawn from
use immediately.

1.4 Mounting options and angle settings
One 9 mm (0.35") hole is provided at each end of the tie bar to
attach the bracket directly to the ceiling.
Each end of the bracket is equipped with a semi-circular slot to
allow the subwoofer to be vertically aligned within a range of 60°
(±30).
1.5 Assembly
Attaching the bracket to ceilings
NOTICE!
Only use mounting parts (fixing anchors and screws) that are
suitable for the intended application.
Observe the occurring extraction forces acting on the fixing
anchors and screws. The rated extraction force is 620 N.
To attach the bracket to the ceiling, use the holes shown in the
graphic opposite to provide adequate support.
A corresponding fixing template is supplied with these mounting
instructions. Refer to Þ Chapter 2 "Z5557 Fixing template"
on page 7.
Preparing the cabinet
The threaded inserts of the cabinet are covered by dummy caps in
cabinet color. To remove the caps, proceed as follows:
1. Cut out the caps along the recessed spline using an
appropriate cutting knife.
2. Carefully take off the caps and ensure the cabinet coating is
not peeled off.

Attaching the bracket to the cabinet
NOTICE!
Only use the supplied and specified screws [2], otherwise there is
a risk of damaging the threaded inserts.
Always use the spring washers [3] and U washers [4] to prevent
the bolts from slackening.
Always place the rubber pads [5] between the bracket and the
cabinet to prevent the cabinet coating from scratching during
assembly and adjustment.
Tools required:
▪ Open-ended spanner/wrench (size #17)
1. Starting on one side, first align one hole of the rubber pad
with one threaded insert.
2. Insert one screw together with the spring and U washers.
3. Align the second hole of the rubber pad with the second
threaded insert.
4. Insert the second screw together with the spring and
U washers.
5. Tighten both screws.
↳This will simplify the attachment of the rubber pad on the
opposite side.
6. On the opposite side, proceed in the same manner.
1.6 Adjustments
To align the cabinet to its desired angle, proceed as follows:
1. Slightly slacken all screws.
2. Align the cabinet to its desired angle.
3. Finally tighten all screws.
