Specications and Instructions
CAUTION ! Before attempting to suspend any Versarray™ Rigging Hardware with or without speak-
ers hung from it, consult a certied structural engineer. e Halo/Fly Bar and/or speaker array can

ing hardware. All associated rigging is the responsibility of others.
Description
e Crest Audio® Versarray™ Mk III Two Foot Fly Bar is used in conjunction with the Crest Audio® Versar-
ray™ Mk III Halo to provide additional multiple single-point hang balance points, increasing the number
available on the Halo alone from 8, to a total of 29 discrete points.
is part is an optional piece of the overall rigging system, and it may not be needed if the center bar of the
Halo provides an acceptable balance point for a single-point hang of the line array as congured and own.
It can also be used to y the Versarray™ Mk III Halo via two hang points at either end of the Versarray™ Mk
III Two Foot Fly Bar. See Figure 1 for the labeled FLy Bar holes.

CAUTIONS
WARNING !
IMPORTANT INFORMATION FOR STRUCTURAL ENGINEER AND RIGGING PERSONNEL. Before
you fly the array, be sure to inspect the rigging and flying hardware to insure that it is mechanically sound
and has not been damaged. There should be no significant distortion of the shape of the Halo cou-pling
ears, cabinet straps, Angle Slider bracket or Rail, Pivot Bar or a fly bar, and the hardware should be
checked for tightness.
CAUTIONS:
IF ANY OF THE BRACKETS, RAILS, CABINET STRAPS, PIVOT BAR OR THE FLY BAR HAS BEEN
DAMAGED OR DISTORTED, DO NOT USE, AND DO NOT FLY THE ARRAY UNTIL THEY CAN BE
REPLACED OR REPAIRED!
DO NOT USE THE PIVOT BAR OR ANGLE SLIDER BRACKET AS HANDLES TO TRANSPORT THE
CABINETS!
DO NOT TRANSPORT THE CABINETS IN ARRAY CONFIGURATION COUPLED TOGETHER, EX-CEPT
WITH THE RECOMMENDED TRANSPORT CART AND IN THE STIPULATED MANNER FOR THAT
CART. TRANSPORT IN SUCH AN UNAPPROVED MANNER VOIDS THE WARRANTY, AND THE
SYSTEM WOULD BE CONSIDERED UNSAFE TO BE FLOWN AFTER SUCH AN UNAPPROVED
TRANSPORT EVENT.
The Crest Audio® Versarray™ loudspeaker models should be suspended overhead only in accordance with the
procedures and limitations specified in the User’s Manual and possible manual update notices. This system
should be suspended with certified rigging hardware by a rigging professional and in compliance
qualified
with local, provincial or national suspension ordinances. ALWAYS USE PROPER GRADE
HARDWARE.
It is the responsibility of the user and installer to make sure that any Crest Audio® Versarray™
installation meets any applicable local, state or federal safety regulations.
CAUTION: Before attempting to suspend this speaker, consult with a certified structural engineer.
Speaker can fall from improper suspension, resulting in serious injury and property damage. Use only the
correct mating hardware. All associated rigging is the responsibility of others. Maximum enclosure angle 30
degrees. Failure to follow proper rigging specifications listed in the manual may result in injury or death.
Whenever possible, in addition to the nominal primary mounting method, use a suitable safety chain or wire
rope attached to one of the other groups of fly points, and firmly attached to a suitable structural member as
indicated by a certified structural engineer. CAUTION: ALWAYS USE SAFETY CHAIN OR WIRE ROPE.

DO NOT USE THE FLOWN ARRAY AS A LADDER, OR ATTEMPT TO CLIMB UP TO THE RIGGING
OR THE HALO USING THE FLOWN LINE OF VR112 CABINETS!
DOING SO IS LIKELY TO DAMAGE THE CABNET HARDWARE AND RIGGING, AS WELL AS POSE A
SERIOUS AND DANGEROUS SAFETY HAZARD!
Correct use and seating of the Quick Release Push Lock Pins Used with most all Versarray™ rigging
hardware
When using the Quick Release Positive Lock Pins, when the Quick Release Push Lock Pins are inserted,
they should be fully seated, so that the black shoulder near the end of the pin has been placed ush with the
side of the bracket, or as far in as the pin hole cavity will allow it to be inserted.
You will have to fully depress the center push-button to do this.
You should not be able to pull these pins out unless the center push-button is fully depressed.
Use of the Versarray™ Mk III Two Foot Fly Bar with the Versarray™ Mk III Halo
Specic Instructions for the basic ying and hanging the Versarray™ Mk III Halo will not be supplied.
It provides and follows industry standards for attaching rigging and y hardware, as well as providing for
the currently popular practice of hanging the array via a single hang point that can be a suitably rated chain
hoist motor system.
Seek the recommendations of a certied structural engineer or an experienced rigging professional for any
questions about this type of use of the Versarray™ Mk III Halo.
Instructions for maximizing the single point hang balance point options are provided, due to the unique
exibility the Versarray™ system provides.
Single Point Hang - Balance Point Options
e Crest Audio® Versarray™ Mk III Halo has 8 single-hang balance points provided via the center bar of
the Halo frame. In many cases, using one of these with a suitable shackle and rigging system will provide a
suitable starting angle for the array once it is own and guyed.
If the particular conguration chosen for the Versarray™ 112 Mk III line array hang does not fully balance
to your needs using only the Versarray™ Mk III Halo, then an optional Versarray™ Mk III Two Foot Fly Bar
can be added to the Halo, and the combination now provides 29 discrete balance points to choose from.
