SAFETY STATEMENT FOR QUICKFLY RIGGING

Please read this Statement carefully and in its entirety. It contains important information regarding safety issues, including guidelines for general safe use of rigging systems as well as advisories on government regulations and liability laws.
This Statement assumes that the owners and/or users of a QuickFly
®
system are knowledgeable and experienced in the areas of rigging and flying loudspeaker systems. Many issues of crucial concern, such as the determination of appropriateness and condition of venue rigging points, cannot be addressed here. Therefore, the user must assume all responsibility for the appro­priate use of QuickFly systems in any particular location or circumstance.
The suspension of large, heavy objects in public places is subject to numerous laws and regulations at the national/federal, state/provincial, and local levels. The user must assume responsibility for making sure that use of any QuickFly system and its components in any particular circumstance or venue conforms to all applicable laws and regulations in force at the time.

Load Ratings and Specifications

Long-term safe operation is a central concern in the design and manufacture of any rigging/flying system. Meyer Sound has taken great care in material selection and component design. In all critical cases, load points are redundant, with a safety mar­gin that allows one or more load points to fail while maintaining system integrity. After manufacture, all load-critical system components are individually inspected.
All load ratings and other specifications given in this manual are the result of accepted engineering practice and careful test­ing. However, such specifications and ratings are subject to change. Users are advised to check the QuickFly section of the Meyer Sound website at
www.meyersound.com
or contact Technical Support at regular intervals to check for updated or revised information.

CHAPTER 1: INTRODUCTION

Regulatory Compliance

The design and safe working load (SWL) ratings of the QuickFly system are intended to be in compliance with all known reg­ulatory statutes currently applicable in the United States. Unless otherwise specified, all working loads are based on a 7:1 safety factor. However, as noted above, there are wide variations internationally in the regulations and practices applying to suspension of sound systems in public places. Although regulations in the United States are generally among the most stringent, safety codes may be even stricter in a few localities (such as those highly prone to earthquakes). In addition, appli­cable safety codes are open to interpretation: Government officials in one location may have a stricter interpretation than another local official, even when operating under the same regulations and in the same legal jurisdiction.
Consequently, users of QuickFly rigging systems should be prepared to take additional safety assurance measures beyond those outlined in this Statement. IN ALL CASES, IT IS THE RESPONSIBILITY OF THE USER TO MAKE CERTAIN THAT ANY MEYER SOUND LOUDSPEAKER SYSTEM IS SUSPENDED IN ACCORDANCE WITH ALL APPLICABLE NATIONAL/FED­ERAL, STATE/PROVINCIAL, AND LOCAL REGULATIONS.

Safety Responsibilities “Above the Hook”

In most touring applications of rigging systems, the touring sound provider is normally responsible for ensuring the safety of the suspension system only below the attachment point. The safety and suitability of the attachment point is generally seen as the responsibility of the venue owner or operator. However, this distinction (“above the hook” versus “below the hook”) can be open to interpretation. Touring system operators should double-check to make certain that attachment points are approved and suitably load rated, and that the points used are those identified as such by the venue owner or operator. As an extra precaution, careful inspection of the attachment points is advised before flying, particularly in older venues or those hosting frequent events using large sound and lighting systems. IN ANY CASE, MEYER SOUND QUICKFLY SYSTEMS ARE INTENDED ONLY FOR SUSPENSION FROM APPROVED RIGGING POINTS, EACH KNOWN TO HAVE AMPLE SWL MAR­GINS FOR THE SYSTEM COMPONENTS SUSPENDED BELOW THEM.

Inspection and Maintenance

The Meyer Sound QuickFly systems are an assembly of mechanical devices, and are therefore subject to wear and tear over prolonged use, as well as damage from corrosive agents, extreme impact, or inappropriate use.
BECAUSE OF THE SAFETY ISSUES INVOLVED, USERS MUST ADOPT AND ADHERE TO A SCHEDULE OF REGULAR INSPECTION AND MAINTENANCE. IN TOURING APPLICATIONS, KEY COMPONENTS MUST BE INSPECTED BEFORE EACH USE. Such inspection includes examination of all load-bearing components for any sign of undue wear, twisting, buck­ling, cracking, rusting, or other corrosion. In regard to rust and corrosion, the main components of a QuickFly system are either protected by an exterior coating or made from stainless steel, which is impervious to rust and resistant to most corrosive flu­ids. Nevertheless, normal use and shipping vibrations can wear through the protective coatings, and extremely corrosive fluids (such as battery acid) can cause severe damage with prolonged exposure even to protected parts. Particular attention should be given to screws, bolts, and other fasteners to make certain the fittings are tight and secure. Metal seams and welds should be examined for any sign of separation or deformation. Meyer Sound strongly recommends that written documentation be maintained on each QuickFly system, noting date of inspection, name of inspector, points of system checked, and any anom­alies discovered.
Annual Comprehensive Examination and Test Program
In addition to routine checks on the road for touring systems, Meyer Sound also recommends a careful, comprehensive sys­tem examination and testing “at home” in the warehouse or other appropriate location at regular intervals. Such at home examinations and tests should occur at least once a year, and should include a careful inspection of each component under ideal lighting conditions, and then a final comprehensive check of the entire system after it has been flown.
If any anomalies or defects are discovered that could possibly affect the safety or integrity of the system, affected parts or sub­systems should be replaced in their entirety before that part of the system is flown again.

MG-LEOPARD/900 GRID ASSEMBLY GUIDE

Replacement Parts

Any component found to be defective, or any safety-related component you even suspect might be defective, should be replaced with the equivalent, approved part. Parts specific to a QuickFly system should be ordered directly from Meyer Sound. No attempt should be made to substitute what appears to be equivalent or “mostly the same” generic replacements. Some parts used in QuickFly systems are identical to those used in other rigging applications. To the best of our knowledge, most of these suppliers are reputable and their products are reliable. However, Meyer Sound has no way of assuring the quality of products made by these various suppliers. Therefore, Meyer Sound is not responsible for problems caused by components that were not supplied by Meyer Sound.

Training

QuickFly systems are relatively straightforward and easy to use. However, they should only be used by persons trained in the use of loudspeaker rigging systems, who have mastered key points of assembly, rigging and flying.

CHAPTER 2: 900-LFC GROUNDSTACKS AND CARDIOID ARRAYS

!

GROUNDSTACKING 900-LFC LOUDSPEAKERS (WITHOUT GRID)

900-LFCs can be groundstacked up to three units high, with or without the MRK-900 rigging kit. Protective plastic skids are included on the bottom of the 900-LFC cabinet that align with the slots on the cabinet top. Units can be stacked normally or reversed for cardioid configurations. When groundstacking 900-LFCs, make sure the skids for each unit align with the slots in the cabinet tops. When equipped with the MRK-900 rigging kit, the 900-LFC can be groundstacked on the MG-LEOPARD/ 900 grid with LEOPARDs for mixed groundstacks (see Chapter 10, “Groundstacking with the MG-LEOPARD/900 Grid”).
900-LFC Groundstack (Without Rigging)
CAUTION: As a safety precaution, to avoid tipping, a maximum of three cabinets is supported for ground-
stacked 900-LFCs.
NOTE: 900-LFCs need not be equipped with the MRK-900 rigging kit for secure groundstacking of up to three
cabinets.
11
CHAPTER 2: 900-LFC GROUNDSTACKS AND CARDIOID ARRAYS

900-LFC CARDIOID ARRAYS

The 900-LFC can be configured in cardioid arrays to reduce output heard behind the loudspeakers. The loudspeaker’s linearity ensures that cardioid patterns behave accurately even at very high levels. Cardioid arrays are achieved by placing three units coplanar to each other (in either a groundstacked or flown array) with one unit facing the opposite direction. Polarity and delay processing is applied to the rear-facing unit, which yields output that cancels output from the other loudspeakers normally pres­ent behind the units.
900-LFC Cardioid Groundstack (With Rigging)
NOTE: 900-LFCs need not be equipped with the MRK-900 rigging kit for groundstacked cardioid configura-
tions of up to three cabinets.
NOTE: 900-LFC cardioid arrays can also be flown from the MG-LEOPARD/900 multipurpose grid. For more infor-
mation, see Chapter 5, “MG-LEOPARD/900 Multipurpose Grid.”
12
MG-LEOPARD/900 GRID ASSEMBLY GUIDE
NOTE: To achieve an accurate cardioid pattern, Meyer Sound’s MAPP prediction software and the Galileo®
Callisto 616 array processor are required. Use MAPP to calculate the appropriate ratio of forward to rear-facing loudspeakers, as well as the Callisto 616 settings for polarity and delay. A myriad of cardioid and directional configu­rations are possible and can be calculated and predicted with MAPP. For more information, contact Meyer Sound
Technical Support.

2. Attach the MRK-900 endframes and the previously removed grille frame:
!
MG-LEOPARD/900 GRID ASSEMBLY GUIDE
Use a 7/32-inch hex wrench to secure the MRK-900 end frames to the cabinet with the eight outer 3/8-16 x 2.25-inch
panhead socket bolts (PN 101.719) (four each side) and eight inner 3/8-16 x 1.25-inch panhead socket bolts (101.695) (four each side). Apply one or two drops of Loctite to each of the socket bolts before installing them.
NOTE: For all-weather, outdoor installations, use the silver weather-protected panhead socket bolts
(PN 101.219 and PN 101.195).
CAUTION: Make sure the socket bolts are securely tightened but do not over-tighten them. Approximately
15 foot-pounds of torque is recommended.
Use a Phillips screwdriver to secure the grille frame to the cabinet with the six 10-32 x 1.75-inch panhead screws (three
each side). Apply one or two drops of Loctite to each of the panhead screws before installing them.

CHAPTER 4: LOUDSPEAKER GUIDEALINKS

!

LEOPARD GUIDEALINKS

LEOPARD is equipped with four captive GuideALinks that link to adjacent LEOPARDs or 900-LFCs in flown and ground­stacked arrays. Located at the top corners of the cabinet, GuideALinks extend up and into the link slots of the cabinet above it, or into the link slots of the MG-LEOPARD/900 grid or MTF-LYON/LEOPARD transition frame. GuideALinks extend and retract with knobs and are secured with two quick-release pins: one each in the top and bottom cabinets. Each LEOPARD loudspeaker ships with eight 5/16 x 0.063-inch quick-release pins (black button) (PN 134.024).
LEOPARD GuideALinks with Quick-Release Pins, Exploded View
CAUTION: GuideALinks must be secured with the included quick-release pins. At no time should the weight of
the loudspeaker rest on the GuideALink knobs when the links are fully extended (without the pins inserted). Guide­ALink knobs are for extending and retracting the links only.
19
CHAPTER 4: LOUDSPEAKER GUIDEALINKS

LEOPARD Splay Angles

Front GuideALinks attach at splay angles of 0 or +5 degrees. However, the front GuideALinks should almost always be attached at 0 degrees, to ensure that coverage between linked cabinets is continuous. When attached at 0 degrees, the front GuideALinks act as a pivot point between the linked LEOPARDs, with the splay angle between the units determined by the rear GuideALink positions. When attached at +5 degrees, the front GuideALinks add 5 degrees to the splay angle con­figured with the rear GuideALinks, making it possible to achieve splay angles of 11 to 15 degrees. To stow the front GuideA­Links, move them all the way down to STOW and pin them.
TIP: Wide splay angles of 11 to 15 degrees should only be used for downfill coverage, or for steering coverage
away from structures like balconies.
LEOPARD GuideALinks (Exposed) Attached at 0.5 Degrees
Rear GuideALinks attach at splay angles of 0.5 to 10 degrees. The labels next to the rear GuideALinks indicate the splay angle between cabinets and provide a guide for which of the three pinning positions to use to secure the links (see Figure 1 on page 21). As the links are moved down, the splay angle increases. To stow the rear GuideALinks, move them all the way down to STOW and pin them to the center pin position.
NOTE: The splay angles listed on the GuideALink labels are for relative angles between the center axes of the
linked units. For example, setting the GuideALinks to 5 degrees yields a 5-degree downtilt of the lower unit to the upper unit. How the loudspeakers relate to the floor, stage, and seating angles in the venue depends on the orien­tation of the grid, the angles of the loudspeakers in the array above them, and other factors. MAPP prediction software should be used to calculate optimum splay angles for loudspeakers and to predict coverage patterns for arrays.

NOTE: When flying LEOPARDs from the MG-LEOPARD/900 grid, a splay angle of 0 degrees is recommended
for the top cabinet (rear GuideALinks set to 5, front GuideALinks set to 0) to ensure that the cabinet aligns with any lasers or inclinometers mounted on the grid. To add tilt to the top cabinet, the actual grid should instead be tilted with motors attached to the front and rear of the grid. If just one motor is available, you can attach it to one of the 13 center pickup points offset from the center of the grid to achieve the desired tilt (see “Using MAPP to Calculate Single Pickup Points” on page 41).

MG-LEOPARD/900 GRID ASSEMBLY GUIDE

900-LFC GUIDEALINKS

When equipped with the MRK-900 rigging kit, the 900-LFC includes six captive GuideALinks and six mating link slots that link to adjacent units in flown and groundstacked arrays. Located at the top of the cabinet, GuideALinks extend up and into the link slots of the cabinet above it, or into the link slots of the MG-LEOPARD/900 grid, making it easy to link cabinets once they are stacked. GuideALinks extend and retract with knobs and are secured with two quick-release pins: one each in the top and bottom cabinets. GuideALinks accommodate reversed units for cardioid arrays. The MRK-900 rigging kit includes eight 5/16 x 0.63-inch quick-release pins (black button) (PN 134.024).

The 900-LFC’s front and middle GuideALinks are used when stacking LEOPARDs on top of the 900-LFC (see Figure 3).
CAUTION: Do not use the 900-LFC’s middle GuideALinks when flying the loudspeaker below the MG-
LEOPARD/900 grid or when flying it below another 900-LFC. Always use the front and rear GuideALinks when
flying the 900-LFC.

CHAPTER 4: LOUDSPEAKER GUIDEALINKS

900-LFC Splay Angles

Front and rear GuideALinks attach at angles of 0.00, 1.25, 2.50, 3.75, or 5.00 degrees, thereby allowing curved arrays for the 900-LFC. Because the 900-LFC GuideALinks are symmetrical, curved arrays can also include cardioid configurations.
900-LFC Front GuideALinks Label
The labels next to the front and rear GuideALinks indicate the splay angle between cabinets (when the opposing links are set to 0 degrees). As the links are moved up, the splay angle increases. To stow the GuideALinks, move them all the way down to STOW and pin them.
NOTE: When flying 900-LFCs from the MG-LEOPARD/900 grid, a splay angle of 0 degrees is recommended
for the top cabinet (rear GuideALinks set to 0, front GuideALinks set to 0) to ensure that the cabinet aligns with any lasers or inclinometers mounted on the grid. To add tilt to the top cabinet, the actual grid should instead be tilted with motors attached to the front and rear of the grid. If just one motor is available, attach it to one of the 13 center pickup points offset from the center of the grid to achieve the desired tilt (see “Using MAPP to Calculate Single Pickup Points” on page 41).
NOTE: The curved array capability of the 900-LFC is provided to complement (aesthetically) the curvature of
adjacent LEOPARD, LYON, and LEO-M arrays, and to ensure that the physical cabinets of the 900-LFC array do not obstruct the neighboring array's coverage. Curved 900-LFC arrays do not provide directionality for low-fre­quency content.

MG-LEOPARD/900 Grid (Valid Pickup Points Highlighted in Blue)
TIP: The MG-LEOPARD/900 grid supports mixed arrays of LEOPARDs and 900-LFCs without transition hard-
ware. The grid can also be used for groundstacks.
The MG-LEOPARD/900 grid accommodates a variety of pickup configurations with its four corner and 13 center pickup points. To add tilt to the array, attach motors to the front and rear of the grid. If just one motor is available, attach it to one of the 13 center pickup points offset from the center of the grid to achieve the desired tilt (see “Using MAPP to Calculate Single Pickup Points” on page 41). The grid can also be oriented to provide either maximum array downtilt or maximum array uptilt (see “Grid Orientation for Flown Arrays” on page 33).
The MG-LEOPARD/900 grid includes attachment points to accommodate brackets and adapters for lasers and inclinome­ters (see Appendix B, “Laser Bracket”).
CAUTION: Always use the 5/16 x 0.875-inch quick-release pins (red button) included with the MG-LEOPARD/
900 grid to secure the attached LEOPARD or 900-LFC. Do not use the 5/16 x 0.063-inch quick-release pins (black
button) included with the loudspeakers in the grid as they are shorter and will not lock in place.
CAUTION: Always use properly rated rigging hardware. The MG-LEOPARD/900 grid requires 5/8-inch or 3/4-
inch shackles for its pickup points.
