. (Note: If one pickup hinge
is installed incorrectly with the chain at the center
of the track, the second pickup hinge will not fit
into the track cutout.) Key dimensions for the Xrhp
rigging hinges and the enclosure are presented in
Figures 4c
and
5c.
To install an Xrhp pickup hinge into the track of
an enclosure, grasp the hinge base and firmly in-
sert it into the long center cutout in the track,
pressing in until the spring-loaded locking pin is
fully retracted. Then apply pressure to slide the
hinge base sideways towards the end of the track
until the spring-loaded locking pin drops into the
hinge-locking-pin hole in the base of the track.
Once the locking pin is fully engaged, the pickup
hinge base will be immovable in the track. AL-
WAYS CHECK TO MAKE SURE THE PICKUP-
HINGE BASES ARE SECURELY LOCKED INTO
THE TRACK, AND THAT THE LOCKING PINS
ARE FULLY ENGAGED IN THE TRACK BE-
FORE LIFTING ANY LOUDSPEAKER EN-
CLOSURES OVERHEAD.
To remove the Xrhp pickup hinge, grasp the lock-
ing-pin knob and pull out while applying pressure
on the hinge to slide the hinge base toward the
long cutout at the center of the track. The hinge
base will come out of the track once it is aligned
with the center cutout. For added safety, the lock-
ing pin has a special shape which engages with
the track to prevent it from vibrating out of the
track hole during use. If the locking-pin knob
seems difficult to pull out when removing the
hinge, wiggle the hinge base while pulling out on
the knob. When the hinge locking pin is centered
in the track hole, the pin will easily release.
1.4 Rigging Strap Details
Two rigging straps (either two Xrss straps or two
Xrsl straps) are used to attach a pair of enclo-
sures together at the front, or to attach the front of
the top enclosure to an X-Array™-compatible
grid. The short Xrss wire-rope rigging strap,
shown in
Figure 6a
, and the long Xrsl wire-rope
rigging strap, shown in
Figure 6b
, are identical
except for their length. Both consist of two New
Haven NH32102-2 double-stud swivel-ring fittings
connected together with a 4.76-mm (.188-in.) di-
ameter, galvanized and black-plastic-coated, air-
craft wire rope. (See section
3. Rigging-Strength
Ratings, Safety Factors and Special Consider-
ations for a detailed discussion of the structural
strength of the rigging straps.)
Two Xrss straps are typically used to attach the
front of the top enclosure to an X-Array™-compat-
ible grid as shown in
Figure 7a
; however, the Xrsl
may be substituted. Key dimensions for the front
rigging straps on the enclosures are presented in
Figure 7a
. (See section
1.5 Grid Details for a dis-
cussion of the grid.) When the short Xrss rigging
straps are used between the top enclosure and
the grid, the top enclosure may be angled upward
relative to the grid or downward a moderate
amount. When the long Xrsl rigging straps are
used between the top enclosure and the grid, the
enclosure may be hung parallel to the grid, or
angled downward substantially relative to the grid.
Two Xrsl straps are typically used to link two en-
closures together at the front; however, the Xrss
may be substituted. When the long Xrsl straps are
used between enclosures, the bottom enclosure
may hung parallel to the top enclosure or angled
downward substantially relative to the top enclo-
sure. When the short Xrss straps are used be-
tween enclosures, the bottom enclosure may
hung parallel to the top enclosure or angled
downward a moderate amount relative to the top
enclosure. (See the section
2.2 Aiming the Enclo-
sures for details.)
To attach the front of an X-Array™ enclosure to a
building structure, custom wire-rope assemblies
may be fabricated using the New Haven
NH32102-2 double-stud swivel-ring fitting. That
same fitting may be used on custom wire-rope
assemblies to secure the front of an enclosure to
a custom grid that does not have track at the
front.
In certain circumstances, two New Haven
NH32102-2 double-stud swivel-ring fittings may
