Instructions/DSA Series Fly-Bar Kit
and Enclosure Connecting Kit
DESCRIPTION:
The DSA Fly-Bar Kit and Enclosure Connecting Kit are used for suspending DSA Loudspeakers.
WARNING: Suspending anything, especially overhead of people, should be done with extreme caution. Always engage the services
of a certified professional who is qualified to determine the requirements for, and to implement overhead rigging. Only persons with
the knowledge of proper hardware and safe rigging techniques should attempt to suspend DSA Loudspeaker Systems overhead.
Failure to follow these precautions may result in equipment damage, injury, or death.
WARNING: When suspending DSA Enclosures, the Threaded Standoffs, Support Strap Studs, and Connecting Strap Studs carry
the weight of the Loudspeaker as a shear load, transferring it to the Straps themselves. For proper transfer of the load, all Standoffs
MUST slide into the Half-Moon Cutouts and seat against the Support Straps. Do not, under any circumstances, suspend a
Loudspeaker if any Standoff is not fully seated against its Support Strap surface. Failure to follow this warning may result in equip-
ment damage, injury, or death.
CAUTION: For each of these procedures, make sure the correct end of the Loudspeaker, Signal End or Power End, is “up”
for the intended application.
WLL (Working Load Limit)
The Fly-Bar Kit will support the weight of any DSA Cluster permitted in the DSAPilot control software. The Enclosure
Connecting Kit is required for and will support the weight of additional Enclosures in over-under Clusters permitted in
the DSAPilot software. Permitted Clusters with side-by-side Enclosures require two Fly-Bar Kits, one for each Enclosure.

USAGE
Install a DSA Fly-Bar on the Loudspeaker Enclosure to attach user-supplied rigging hardware for suspending a DSA Loudspeaker.
Install a DSA Enclosure Connecting Kit to attach each additional DSA Loudspeaker underneath a suspended DSA Loudspeaker.
SUSPENSION (Requires one Fly-Bar Kit)
1. Loosely attach the four Support
Straps to the Fly-Bar with the
four supplied Bolts, Flat Washers
and Lock Nuts.
2. Orient the Fly-Bar so
the wide side is to the
front of the Loudspeaker.
Slide the four Support
Straps, loosely attached
to the Fly-Bar, into the
four Enclosure Channels.
3. Align the two Threaded Studs
on each Strap with the Half-
Moon Cutouts in each Channel.
Screw a Threaded Standoff
onto each Support Strap Stud.
4. Ensure all Standoffs
are fully inserted
into the Enclosure
Channel Cutouts and
are seated against
the Support Straps.
6. Apply one drop of the supplied Loctite
242 to each tightened Standoff as shown
in the drawing. Once applied, allow the
Loctite to cure undisturbed for a minimum
of 6 hours or according to its directions.
SUSPENDING ADDITIONAL LOUDSPEAKERS BELOW (Requires an Enclosure Connecting Kit for each)
CAUTION: This procedure requires that the two Enclosures be vertically positioned when installing the Connecting Kit.
The Connecting Straps are not designed to withstand lateral loads. If the Enclosures are connected while in other than a
vertical position and then lifted to a vertical position, lateral loading of and possible damage to the Straps will occur.
1. Lift the first Enclosure high enough to allow the second
Enclosure to be placed directly underneath it in a vertical position.

3. Fasten the 4 Connecting Straps
to the upper Enclosure Channels
onto each Threaded Stud. Do not
tighten the Threaded Standoffs
at this time.
7. Attach the supplied 3/8”Shackles to
either the front and back or side holes
in the Fly-Bar. Use the Shackles as the
attachment points for suspension hard-
ware that is load-rated for the weight
being suspended.
4. Bring the Enclosures together so
the Connecting Straps slide into
the bottom Enclosure’s Channels.
Align the Threaded Studs with the
Half-Moon Channel Cutouts in
the lower Enclosure.
5. Using a 1/2”wide, flat-tip Screwdriver, firmly tighten all
Standoffs. Tighten the four Fly-Bar Lock Nuts installed
in Step 1 with a Phillips Screwdriver and Wrench.
2. Slide all four Connecting Straps
up into the upper Enclosure Chan-
nels. Align the Threaded Studs to
the Half-Moon Channel Cutouts.
