Important Safety Information
Do not use this yoke bracket to attach the HPR 122i to a wall or other architectural element!
Attach the base of this yoke bracket to the load-bearing structure using appropriate load-
rated hardware approved for the application.
WARNING! Before placing, installing, rigging, or suspending any speaker product, inspect all hard-
ware, suspension, cabinets, transducers, brackets and associated equipment for damage. Any
missing, corroded, deformed or non-load rated component could significantly reduce the strength
of the installation or placement. Any such condition severely reduces the safety of the installation
and should be immediately corrected. Use only hardware which is rated for the loading conditions
of the installation and any possible short-term unexpected overloading. Never exceed the rating of
the hardware or equipment.
Consult a licensed, professional engineer when any doubt or questions arise regarding a physical
equipment installation. Ensure all local, state, and national regulations regarding the installation,
operation, and safety of this equipment are understood and adhered to.
Attaching the Yoke to the Loudspeaker
The yoke bracket is designed to attach only to the side rigging points on the loudspeaker as shown in Figure 1.
1- To attach the bracket to the loudspeaker enclosure, you
must first remove the M10 bolts from the enclosure’s side rig-
ging points (6mm hex wrench required).
2- Attach the yoke to the rigging points using the M10 Hex
Head Bolts included with the bracket. Note the hardware order
shown in Figure2. Ensure the rubber flat washers are installed
between the bracket and the loudspeaker enclosure. The steel
flat and lock washers are to be installed between the bolt and
the outside bracket surface. The lock washer is the outermost
washer, located directly under the head of each bolt.
3- Tighten bolts snuggly, just to the point where the yoke is
held in place but able to rotate. Set desired tilt and tighten the
two M10 bolts to secure the loudspeaker in place.
