Installing the U-bracket
WARNING:
The loudspeaker and all mounting components must be inspected annually by a qualified
professional who is trained and certified in suspending loudspeaker systems. All rigging parts and
components used in the suspension of the loudspeaker system should be visually inspected for signs
of cracking, bending, water damage, corrosion, de-lamination, or any other condition that could
comprise the system's integrity and create a dangerous falling hazard.
1. Secure the U-bracket via your chosen mounting method.
Note:
Ensure the bracket is installed in the correct orientation to allow for desired direction of loudspeaker
install. Ensure that your chosen mounting method meets any necessary safety requirements.
2. Remove the plastic plugs in the center of either side of your loudspeaker module.
3. Apply adhesive-backed rubber gaskets aligned over mounting holes.
4. Secure the loudspeaker module to the bracket using the center inserts and included M10 hardware.
5. Adjust the loudspeaker module to your desired angle.
6. Secure the loudspeaker module by inserting the two M6 rotation-locking screws into the correct curved
slots.
Note:
Torque all the screws to 20.3 to 27.1 newton·meters (15 to 20 pound·feet).
