Installation
Mounting AMU Loudspeakers with the U-bracket
CAUTION: Before installation, determine the location and position of your AMU loudspeaker. Only
remove the plastic inserts that are necessary for your installation. The plastic inserts are factory sealed
to prevent water damage. If any insert is left unsealed after installation, the weather-resistant integrity
of your loudspeaker could be compromised.
1.
Choose a mounting location that will safely support the weight of the loudspeaker.
2. Remove packing materials and place the loudspeaker on the floor beneath the planned suspension point.
3. Using the included T3 square drive, remove the center plastic insert and one other insert (determined by
your loudspeaker installation design) on each side of the loudspeaker.
4. Insert an M8 screw through a rubber washer and into the center threaded hole on each side of the
loudspeaker. Do not tighten.
5. Hold the U-bracket in the mounting location and mark the holes.
6. Drill holes into the mounting surface using previously marked positions.
7.
Attach the U-bracket to the building surface using appropriate fasteners (not included).
CAUTION: For attaching U-brackets to a surface, choose fasteners that are consistent with all local
building codes and requirements to support the weight of the loudspeaker.
8. Hang the loudspeaker on the bracket by lowering the M8 screws into the bracket slots, keeping the rubber
washers between the bracket and the speaker enclosure.
9. Connect your wiring to your loudspeaker.
10. Feed the wiring through the gland nut on the input panel cover and tighten the gland nut (see Securing
the Wiring on page 16).
11. Attach the input cover using the included M4 screws (see Attaching the Input Panel Cover on page 17).
12. Position the loudspeaker in your desired pitch angle.
13. Insert an M8 screw through the remaining open insert on each side of the loudspeaker.
14. Tighten the four M8 screws with a 10-millimeter socket tool using a torque not to exceed 13.6 to 20.3
newton·meters (10 to 15 pound·feet).
