This yoke mount is specifically for mounting the QSC HPR 122i loudspeaker to a structural support element (lighting or soundstage truss or other load bearing truss, etc.). Additionally, it may be used vertically oriented atop a
35mm loudspeaker pole mount allowing up- or down-tilt. It is not to be used as a wall mount or other attachment

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 loadrated hardware approved for the application.
WARNING! Before placing, installing, rigging, or suspending any speaker product, inspect all hardware, 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.

to the side rigging points.
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 rigging 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.

Installation Options
The yoke bracket can be used to support the HPR 122i in several ways.
Yoke above loudspeaker enclosure (Figure 3) - If using the yoke
bracket positioned above the enclosure, attach to the enclosure using the outermost set of mounting holes in the bracket’s arms.
If single point bracket attachment to the support structure is
used, ensure the support hole just right of the loudspeaker‘s
centerline is used in order to keep the enclosure’s weight balanced.
Yoke below loudspeaker enclosure (Figure 4) - If using the yoke
bracket positioned below the enclosure, attach the yoke to the enclosure using
either set of mounting holes in the bracket’s arms.
Yoke behind loudspeaker enclosure (Figure 5) - If using the
yoke bracket positioned behind the enclosure, use the innermost set of mounting holes in the bracket’s arms. Do not use the outermost set of holes!
If the yoke bracket is behind the loudspeaker, the inner set of
mounting holes (on the brackets arms) must be used.

Third party loudspeaker pole stand mount (Figure 6) - The
yoke bracket may be attached to a third party loudspeaker pole stand mount.
This allows the user to mount the HPR 122i on a 35mm loudspeaker pole and be
adjusted for up- or down-tilt, as required. The bracket’s mounting hole pattern
fits most available mounts. For a list of compatible pole mounts, please visit
http://www.qscaudio.com.
When attaching the pole mount, use the pole mount holes that
result in the center of the pole being offset to the right of the
loudspeaker’s centerline (as viewed from the front of the
enclosure).
Do nothing- Keep in mind, if you do not know what you are doing, don’t
mount this loudspeaker to anything, including the yoke bracket. Consult professional assistance if unsure about any loudspeaker mounting or suspension topic
or procedure.
