8.3.2 R1YOKE MOUNTING PROCEDURE (See FIGURE 3)
Normally the yoke should first be attached to the R1 then the entire assembly mounted to a structure. However
in some cases it may be desirable to mount the yoke and secure it in place before mounting the R1 to the yoke.
Depending on the situation the sequence of the following mounting procedure may have to be modified to
facilitate the work. Nonetheless, the instructions and precautions about use of the hardware should still be
followed. The R1YOKE is attached to the R1 and the Securing Strap is used to lock in the angle of the R1
within the yoke.
1. To attach the yoke to the R1, first determine whether the yoke will be attached to the sides or top/
bottom of the loudspeaker. This will depend on what the yoke is to be mounted to and the how the R1
must be oriented when positioned for proper coverage (See SECTION 8.2). There are 3 holes on each
side of the yoke. The particular holes to use will depend on the clearance due to the aiming angle of the
R1 needed within the yoke.
2. Once the position of the yoke is determined, remove two supplied 1/2-13 stainless steel mounting
bolts, with the lock, flat, and rubber washers from the mounting points where the yoke is to be attached.
3. Position the loudspeaker within the yoke making sure that the large rubber washers sit between the
yoke and the enclosure. Screw the 1/2-13 x 1-1/4 in. (32 mm) bolts, supplied with the R1, into the
mounting holes using the rubber washers, flat washers, and lock washers removed in step 2. Tighten
only enough so as to allow the yoke to move as needed for the rest of the procedure. The rubber washer
has a 7/16 in. (11 mm) hole so it fits quite snugly around the mounting bolts to form the weather seal for
the R1 mounting hole. It also provides some friction to help hold the yoke in position until completely
secured.
4. Mount the R1 and its attached yoke to the structure that will support it. If the center hole on the yoke
crossbar is used as one of the yoke mounting points you need to attach the attach the Securing Strap to
this hole at the same time you mount the yoke to the structure that will hold the R1 assembly. In addition
to attaching the Securing Strap to the yoke, the supplied stainless steel 1/2-13 x 1-1/4 in. bolt (32 mm),
1/2 in. flat washer, 1/2 in. lock washer, and 1/2-13 hex nut can be used as the mounting bolt for the yoke.
In any case, the Securing Strap attaches to the yoke using the end with a single 9/16 in. (14 mm) hole in
it. The Securing Strap is positioned on the underside of the yoke crossbar.
5. After properly securing the yoke to the structure, adjust the final aiming angle of the R1. Once the
aiming angle is set, carefully bend the Securing Strap towards the nearest mounting point on the R1 so
that one of the series of holes in the Strap lines up with the selected mounting point. This may involve
forming the strap into a "U" shape (as shown in FIGURE 3 "Assembled View") to reach one of the
remaining side mounting points or the rear mounting point.
6. Attach the Securing Strap to the mounting point on the R1 enclosure determined in step 5 using the
1/2-13 x 1-1/4 in. bolt, rubber washer, flat washer and lock washer supplied with the R1 mounting point.
Make sure that the rubber washer is located between the Securing Strap and the enclosure.
7. Firmly tighten the bolts holding the yoke to the R1 enough to seat the lock washer. Be careful not to
over-tighten as, given the size wrench that typically will be used, it is possible to apply excessive torque.
8. Lastly ensure that the attachment bolt used to attach the Securing Strap to the R1 is securely
tightened.
CAUTION:
Any of the mounting bolts supplied with the R1 that are not used for mounting must be left in
place with their rubber washers and firmly tightened to maintain the integrity of the weatherproofing.
