Before You Begin – Recommended Tools
• 10 mm sockets and socket wrenches – for M8 bolts on U-bracket
• T3 square drive (included) – for removing plastic inserts

CAUTION: Do not place loudspeakers resting on their grilles.
To install the RMU loudspeakers with the included U-bracket:
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 plastic insert on each end of the loudspeaker.
CAUTION: Do not attach the loudspeaker to the U-bracket using the plastic inserts.
4. Insert one M8 bolt and rubber washer into the threaded hole on each end of the loudspeaker. Do not tighten.
5.
Hold the U-bracket in the mounting location and mark the holes.
CAUTION: For attaching U-brackets to the surface, choose fasteners that are consistent with all local building codes and require-
ments to support the weight of the speaker (refer to "Table 1: Weights of RMU Loudspeakers"). As a general guideline, use 5/16" x
3" lag screws into wood and 5/16"-18 double expansion anchors into concrete and masonry block.
6.
Drill holes into mounting surface using previously marked positions.
7.
Attach the U-bracket to the building surface using the required fasteners specified in Step 3.
8. Hang the loudspeaker on the bracket by lowering the M8 bolts into the bracket slots keeping the rubber washers between the
bracket and the speaker enclosure. See Figure 8.

9. Position the loudspeaker in the desired pitch angle.
10. Tighten the 2 bolts with a 10 mm socket tool using a torque not to exceed 15 to 20 foot-pounds (21 to 28 Newton-meters).
Note: Optionally, for more secure mounting of pitch angles, a wood screw may be inserted into the small hole in the side of the U-brack-
et and tightened into the wood enclosure.
11. Connect field wiring and test loudspeaker operation.
