CHAPTER 1: INTRODUCTION 8
CHAPTER 2: 1100-LFC GROUNDSTACKS AND CARDIOID ARRAYS GROUNDSTACKING 1100-LFC LOUDSPEAKERS 1100-LFCs can be groundstacked up to four units high, with or without the MRK-1100 rigging kit. Protective, plastic skids are included on the bottom of the 1100-LFC cabinet that securely align with the slots on the cabinet top. Units can be stacked normally or reversed for cardioid configurations. When groundstacking 1100-LFCs, make sure the skids for each unit align with the slots in the cabinet tops.
CHAPTER 2: 1100-LFC GROUNDSTACKS AND CARDIOID ARRAYS 1100-LFC CARDIOID ARRAYS The 1100-LFC low-frequency control element is defined by its sonic linearity in reproducing low-frequency transients at high, continuous output levels with very low distortion. This ultra low distortion, coupled with exceptional headroom and optimized rigging options, makes the 1100-LFC ideal for low-frequency directional applications for large-scale tours and installations.
CHAPTER 3: MRK-1100 RIGGING KIT The optional MRK-1100 rigging kit allows the 1100-LFC to be flown from the MTG-1100 top grid. The rigging kit is available as a factory-installed option or as a field upgrade and uses rugged GuideALinks and intuitive quick-release pins to securely link adjacent loudspeakers in groundstacked and flown array configurations. MRK-1100 RIGGING KIT CONTENTS The MRK-1100 rigging kit includes the following components: PN 40.220.027.01 Quantity Part Number Item 4 45.207.126.
CHAPTER 3: MRK-1100 RIGGING KIT INSTALLING THE MRK-1100 RIGGING KIT To install the MRK-1100 rigging kit: 1. Use a 7/32-inch hex wrench to remove the 16 3/8-inch flathead socket bolts from the 1100-LFC (8 on each side of the cabinet). 2. Apply 1 or 2 drops of Loctite to each 3/8-inch flathead socket bolt. 3. Secure the four rigging bars to the 1100-LFC cabinet with the 3/8-inch flathead socket bolts. Orient the rigging bars with the GuideALinks up and the GuideALink knobs facing away from the cabinet.
MG-MINA GRID ASSEMBLY GUIDE 1100-LFC GUIDEALINKS When equipped with the MRK-1100 rigging kit, the 1100-LFC includes four captive GuideALinks that link to adjacent units in flown and groundstacked arrays. Located at the top corners of the cabinet, the GuideALinks extend up and into the link slots of the cabinet above it (or into the link slots of the MTG-1100 top grid). The links extend and retract with recessed knobs and are secured with quick-release pins.
CHAPTER 3: MRK-1100 RIGGING KIT When linking 1100-LFCs, two quick-release pins are required for each GuideALink: one to secure the link in the bottom unit, and one to secure the link to the top (linked) unit. Eight 1/2 x 1.25-inch quick-release pins (blue) are included with the MRK-1100 rigging kit. Loudspeakers are linked at a fixed splay angle of 0 degrees.
CHAPTER 4: MTG-1100 TOP GRID The MTG-1100 top grid flies 1100-LFC arrays of up to 12 cabinets at a 7:1 safety ratio, or up to 16 cabinets at a 5:1 safety ratio. The grid accommodates a variety of pickup configurations with six pickup points, three each on the front and rear of the grid. The grid also includes 0.28-inch, center attachment points that accommodate brackets and adapters for lasers and inclinometers.
CHAPTER 4: MTG-1100 TOP GRID TIP: The MTG-1100 top grid can travel installed on top of 1100-LFC stacks. TIP: The MTG-1100 top grid includes 0.28-inch, center attachment points that accommodate brackets and adapters for lasers and inclinometers.

CHAPTER 5: MTG-1100 PICKUP CONFIGURATIONS The MTG-1100 top grid accommodates a variety of pickup configurations with its six pickup points, three each on the front and rear of the grid. When possible, use the front and rear pickup points to change the tilt of the grid with the front and rear motors. You can also bridle between pickup points for greater stability, as compared to single front and rear pickup points. ! CAUTION: Always use properly rated rigging hardware.
CHAPTER 5: MTG-1100 PICKUP CONFIGURATIONS THREE PICKUP POINTS The MTG-1100 top grid supports the following configurations with three pickup points. 3 to 2 Center/Corner Point Configuration (Left), 3 to 2 Corner/Center Point Configuration (Right) ! ! 20 CAUTION: When suspending MTG-1100 arrays from one or two motors, make sure each motor and ceiling pickup point (above the hook) are rated to hold the total weight of the grid and array.
MG-MINA GRID ASSEMBLY GUIDE FOUR PICKUP POINTS The MTG-1100 top grid supports the following configurations with four pickup points. 4 to 1 Corner Point Configuration (Left), 4 to 2 Corner Cross Point Configuration (Right) ! ! ! CAUTION: When suspending MTG-1100 arrays from one or two motors, make sure each motor and ceiling pickup point (above the hook) are rated to hold the total weight of the grid and array.

CHAPTER 6: MVP-LEO-M VEE PLATE The optional MVP-LEO-M Vee plate provides ±21 degrees of horizontal rotation for the MTG-1100 top grid. The bottom of the Vee plate attaches to the grid’s rear center attachment point. The top corners of the Vee plate attach to two motors, which, when adjusted, affect the horizontal rotation of the grid.
CHAPTER 6: MVP-LEO-M VEE PLATE 24
CHAPTER 7: MAS-1100 ARRAY SPACER The optional MAS-1100 array spacer can be placed between cabinets to lengthen 1100-LFC arrays, improving vertical directionality. Similar to an 1100-LFC equipped with the MRK-1100 rigging kit, the MAS-1100 array spacer includes four captive GuideALinks that extend up and into the link slots of the cabinet above. The links extend and retract with recessed knobs and are secured with the same 1/2 x 1.50-inch quick-release pins included with the 1100-LFC.

CHAPTER 8: MCF-1100 CASTER FRAME The optional MCF-1100 caster frame safely supports up to three 1100-LFCs for transport, making it easy to assemble and disassemble arrays in blocks of three cabinets. The caster frame’s sturdy construction allows it to be conveniently moved with forklifts. The MCF-1100 can also be used to support 1100-LFCs in groundstacked configurations. MCF-1100 Caster Frame 1100-LFC cabinets need not be equipped with the MRF-1100 rigging kit for transport with the caster frame.
CHAPTER 8: MCF-1100 CASTER FRAME 1100-LFC cabinets equipped with the MRF-1100 rigging kit provide for more secure transport as the bottom cabinet can be linked and pinned to the caster frame (see Figure 2). Each of the three cabinets can be linked and pinned together as well. Figure 2: MCF-1100 Caster Frame with 1100-LFC Stack with Rigging Kits (MTG-1100 Top Grid on Top) TIP: The MTG-1100 top grid can travel installed on top of 1100-LFC stacks.

CHAPTER 8: MCF-1100 CASTER FRAME SAFETY GUIDELINES FOR THE MCF-1100 CASTER FRAME ■ Do not stack more than three 1100-LFCs on the caster frame. ■ Use straps when transporting 1100-LFCs that have not been fitted with the MRK-1100 rigging kit. ■ Avoid moving stacks in the front-to-back direction of the 1100-LFCs (the long side); always move stacks sideways to avoid tipping. ■ When lifting an 1100-LFC stack with a forklift, always keep the forks wide and close to the caster frame’s wheels.
APPENDIX A: ASSEMBLING ARRAYS WITH THE MTG-1100 TOP GRID To assemble an 1100-LFC array with the MTG-1100 top grid: 1. Attach the MTG-1100 top grid to the motors: ■ Place the MTG-1100 on the floor or on a road trunk in the approximate location where the rigging points have been established and the motors have been hung. ■ Attach 7/8-inch shackles to the desired attachment points on the MTG-1100 (see Chapter 5, “MTG-1100 Pickup Configurations”).
APPENDIX A: ASSEMBLING ARRAYS WITH THE MTG-1100 TOP GRID ■ Lower the suspended loudspeakers so the bottom cabinet is approximately 1 inch above the top cabinet on the floor. Adjust the placement of the stack on the floor so the top cabinet’s rigging bars align with those of the suspended cabinet above it. Extend the GuideALinks from the top cabinet into the slots of the suspended cabinet above it. Don’t worry if you can’t yet pin the GuideALinks to the suspended cabinet.
