MTG-2100 Load Ratings
The MTG-2100 is designed to support only 2100-LFC cabinets. When the grid is used to suspend 2100-LFC, it has the following maximum load ratings:
Up to sixteen (16) 2100-LFC, no up or down tilt, grid at zero degrees.
Up to eleven (11) 2100-LFC, any grid angle achievable using the grid alone.
Caution
Always model each array configuration in Meyer Sound’s MAPP System Design and Prediction software to determine if the array configuration is within safety limits (5:1 safety factor). Do not suspend an array when the Safety Limits Analysis in MAPP displays “Configuration has exceeded the rated load capacity.”
The weight of any additional items suspended with the array, e. g., cable, motors, motor chain, must be considered when calculating the weight being suspended
Always use properly rated rigging hardware, e.g., wire rope, shackles, hoists, etc. to suspend any load.
Always use the 7/16 x 1.50-inch QRP (lanyard, red button, PN 134.051) included with the MTG-2100 Grid Kit to secure the MTG-2100 Grid to the top 2100-LFC cabinet. These pins are longer than those used for cabinet to cabinet connections.
Do not transport 3-high stacks of 2100-LFC with the MTG-2100 Grid Kit on top. This exceeds the safety limits for tip-over, which may cause injury.
Tip
Do not transport 3-high stacks of 2100-LFC with the MTG-2100 Grid Kit on top. This exceeds the safety limits for tip-over, which may cause injury.
MTG-2100 Grid Hardware Connections
The MTG-2100 Grid does not have a front or rear. It can be turned 180 degrees horizontally without changing its alignment to the cabinets.
When suspended, user-provided 3/4-inch or 7/8-inch shackles connect the hoist(s) to the MTG-2100 Grid. The shackles are connected to the grid, both front and rear. The MTG-2100 must be suspended from both connection points, 24 in (61 cm) apart from each other.
When suspending the MTG-2100 Grid from a single hoist, the minimum bridle leg length is 18 in (46 cm) based on the bridle apex angle being less than 90 degrees.
2100-LFC GuideALinks
2100-LFC GuideALinks Extended
The MTG-2100 Grid connects to the GuideALinks of the top 2100-LFC of a flown array with four 7/16 x 1.50-inch QRP (lanyard, red button, PN 134.051) included with the MTG- 2100 Grid Kit (Figure 17). These quick-release pins are not interchangeable with any other pins used with a 2100-LFC array.
Caution
During array assembly, ensure the quick-release pins are fully inserted and locked (not able to be removed without depressing the quick-release pin lock button).
The quick-release pins are secured to the 2100-LFC loudspeakers with lanyards. For all pin locations, only use pins whose lanyards are attached to the same cabinet when securing GuideALinks.
2100-LFC 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 only used to extend and retract the links.
The locations labeled “B” align with the mounting holes of third-party brackets used to secure laser/inclinometers, e. g., ProSight and ProSight2 mounts. Holes labeled “A” and “C” can accommodate the mounting of custom accessories. For dimensional information, please refer to the CAD (.dwg) drawings available at meyersound.com.

Safety Guidelines for the MCF-2100 Caster Frame
While the MCF-2100 Caster Frame supports up to three cabinets, use extreme caution when moving the caster frame and cabinets to avoid tipping.
When rolling a caster frame and cabinets, slow down when the surface is uneven, e.g., cracks in concrete floors, cable ramps, transitions in floor coverings, etc.
Do not move stacks in the front-to-rear direction of the 2100-LFC cabinets (the long side) as the risk of injury increases. Always move stacks sideways to avoid tipping.
When moving the caster frame with 2100-LFC cabinets, always use the handles of the cabinets and push or pull from one of the ends.
To avoid tipping, transport stacks with all the GuideALinks connected to adjacent cabinets.
The caster frames must be removed before the array is flown.

Assembling Arrays
Warning
BEFORE ASSEMBLING AN ARRAY, REVIEW the Safety Statement for Rigging
User-provided Equipment
Depending on the application and the needs, the following equipment may be considered:
hoists, motorized
rated rigging hardware, e. g., shackles, wire rope, pear rings, etc.
tape measure or laser distance measurement device
load cells - used to measure rigging loads
Note
When using inverted chain motors (motor down), a short length of wire rope or deck chain added between the MTG-2100 Grid Kit and the hook on the motor allows proper collection of the take-up chain in the chain bag without spilling.
Chain Motors with Wire Rope Elevating Hoists Above MTG-2100 Grid Kit.
Array Assembly Preparation
Use acoustic predictions provided by Meyer Sound’s MAPP System Design and Prediction software to determine the optimum array position, number of 2100-LFC loudspeakers required, and the Grid Kit height and angle.
From the MAPP design, document the following array information:
Trim height
Direction cabinet faces (forward/rearward) for gradient arrays
Total array weight
Drive line assignments, Galileo GALAXY output channels
Note
In some regions, regulations require dead-hanging all suspended loads, bypassing the loading of all movable hoists. A dead hang uses a wire rope or chain to carry the suspended load, removing the entire load from the hoisting mech- anism(s) used to raise and lower the array. Ensure the proper rigging equipment is available when needed.
Structural Attachment Point Locations
Install and locate the rigging points above the intended location of the array. The spacing between the rigging attachment points of the MTG-2100 is 24 in (61 cm), along the center line of the grid.
MTG-2100 Grid Rigging Attachment Points
Array Assembly Steps
Because the 2100-LFC cabinets are horizontally symmetrical, when the steps below give instructions related to one side of a cabinet, always duplicate the action on the other side of the cabinet. The duplicate instruction for the other side of the cabinet is not included
These instructions assume the 2100-LFC cabinets are already stacked on caster frames, ready for temporary installation, e. g., touring or one-off events, and that the MTG-2100 Grid is not already connected to the top 2100-LFC cabinet. For installations, it is likely that individual cabinets will be located on the working surfaces below the rigging points and added one at a time to the array. If there are questions, please contact Technical Support by visiting meyersound.com/ contact.
Ready the hoisting mechanism(s).
Caution
Discover and follow all safety regulations and operational rules regarding movement of suspended loads for the region, location, and venue where the system will be deployed.
Securely mount any accessories to the MTG-2100 Grid Kit, e. g., lasers, inclinometers, tape measure, etc.
Prepare 2100-LFC cabinets.
Remove protective covers from stacks of 2100-LFC cabinets and arrange the stacks in the order they will be added to the array.
Note
Leave the GuideALinks of the top cabinet of each stack retracted.
Connect the MTG-2100 Grid to hoist(s).
Locate the MTG-2100 Grid on the floor or a cable trunk directly below the hoist(s).
Connect 3/4-inch or 7/8-inch shackles to the grid.
Connect the hoist(s) to the shackles.
Connect the MTG-2100 to the first stack of 2100-LFC cabinets (Figure 30).
Raise the MTG-2100 Grid until it is higher than the 2100-LFC cabinets being connected.
Move the first stack of 2100-LFC cabinets under the grid.
Lower the MTG-2100 Grid until it is 1 to 2 inches (2.5 cm to 5cm) above the top 2100-LFC cabinet, close enough to allow the front GuideALinks to extend into the GuideALink sockets of the grid.
Remove the quick-release pins that are attached to the MTG-2100 Grid and let them hang from their lanyards.
For the top 2100-LFC, remove the quick-release pin of the front GuideALink, raise the GuideALink with the GuideALink lever, then re-insert the previously removed quick-release pin. Repeat for the rear GuideALink.
– The GuideALinks should extend into the GuideALink sockets of the grid, but won’t be entirely seated.
Lower the grid until it rests on the extended GuideALinks.
Insert the four 7/16 x 1.50-inch QRP (red button, PN 134.051) quick-release pins attached to the grid to secure the GuideALinks of the cabinet to the grid.
Caution
Make sure the quick-release pins are fully inserted and locked, unable to be removed without depressing the button of the quick-release pin
2100-LFC GuideALinks Extended
Connect the strain relief (cable pick) for the cable going to the ground to a pear ring and/or shackle and attach it the rear hoist. If a single hoist is used, consider attaching the strain relief around the central structural member of the grid.
Connect the power and signal cables to the cabinets ready to be hoisted.
Visually inspect the assembly before hoisting, make sure:
The rigging hardware is properly oriented and won’t “jam” or “foul,” especially the shackles
Cables are properly routed and will not be strained, pinched, or damaged when the array is raised.
Each cabinet is linked to the cabinet above it, verifying that each of the four GuideALinks of each cabinet are extended and pinned in place with 7/16 x 0.90-inch QRP (black button, PN 134.065) quick-release pins attached by lanyard to each cabinet
Remove the MCF-2100 Caster Frame
Caution
Do not lift the caster frame by the handles while it is being removed or attached to a cabinet. This creates a pinch point for hands. Only lift the caster frames by the handles when the caster frame is not connected to a cabinet.
Caster Frame Handle Pinch Point
First, remove both front pins that secure the caster frame while supporting the underside of the caster frame by hand
Lower the front wheels to the floor.
Next, remove both rear pins that secure the caster frame while supporting the underside of the caster frame by hand.
Lower the rear wheels of the caster frame to the floor.
Unless it is the last stack to be flown, leave the quick-release pins dangling from their lanyards.
Prepare to connect another stack of loudspeakers.
Ensure the connected cabling has enough slack to not be strained, pinched or damaged as the array is raised.
Raise the array, loading the hoists equally, until the cabinets are about 6 inches (15 cm) higher than the next stack of cabinets to be attached.
Move the stacked cabinets under the suspended cabinets, aligning the corners.
Make sure the GuideALinks of the top stacked cabinet are retracted.
Caution
Do not attempt to “land” the suspended cabinets on a stacked cabinet with the GuideALinks extended. Collision of the GuideALinks and the GuideALink sockets will cause excessive wear over time. Collision of an extended GuideALink and the wooden bottom of a cabinet above it can puncture or damage the cabinet.
Lower the suspended cabinets within 1 to 2 inches (2.5 to 5 cm) above the top of the cabinet to be connected.
Connect the next stack of loudspeakers.
For the cabinet to be connected, remove the quickrelease pins and extend the front and rear GuideALinks into the link sockets of the suspended cabinet. Reinsert the quick-release pins in the same holes to secure the GuideALinks in the raised position with the 7/16 x 0.90-inch QRP (black button, PN 134.065) attached by lanyards to the cabinet.
Lower the suspended cabinets until their weight is supported by the stacked cabinets.
– The raised GuideALinks keep the flown cabinets aligned to the stacked cabinets.
Secure the front and rear GuideALinks to the suspended cabinets by reinserting the 7/16 x 0.90-inch QRP (black button, PN 134.065) quick-release pins attached to the bottom, suspended cabinet.
Caution
Make sure the quick-release pins are fully inserted and locked, unable to be removed without depressing the button of the quick-release pin.
GuideALinks Extended and Secured to the Cabinet Above with Quick-Release Pins
Note
The lanyards of the quick-release pins may be damaged if quick-release pins are inserted in an adjacent cabinet.
Trim the array in its final position
Caution
Do not tip the array forward or backward while raising the array. All motors should carry the same amount of weight.
Disassembling Arrays
Array Disassembly Preparation
De-energize the electrical system providing power to the loudspeakers.
Disconnect cabling connected to equipment on the ground.
Disconnect any rigging hardware used to secure the horizontal aim of the array.
If the array is dead hung (required in some regions), raise the hoists so they take weight and remove the rigging hardware associated with the dead hang.
Array Disassembly Steps
Because the 2100-LFC cabinets are horizontally symmetrical, when the steps below give instructions related to one side
of a cabinet, always duplicate the action on the other side of the cabinet. The duplicate instruction for the other side of the cabinet is not included.
Before lowering the array, make sure the attached cabling has enough slack and that the area around and under the array is clear of obstructions.
Caution
Discover and follow all safety regulations and operational rules regarding movement of suspended loads for the region, location, and venue where the system will be deployed.
Equalize the motor load (grid angle zero degrees), then lower the array until the bottom cabinet is 1 to 2 inches (2.5 to 5 cm) above the height of the caster frame GuideALink tabs, and move a caster frame under the cabinets.
Connect the caster frame to the bottom of the array.
Caution
Do not lift the caster frame by the handles while it is removed or attached to a cabinet - a hand pinch point is created. Only lift the caster frames by the handles when the caster frame is not connected to a cabinet.
Caster Frame Handle Pinch Point
Caution
Do not attempt to “land” the MTG-2100 Grid on a caster frame. Collision of the caster frame tabs and the GuideALink sockets will cause excessive wear over time.
Remove all four quick-release pins from the bottom GuideALink sockets of the bottom cabinet.
From the underside of the caster frame, lift the front or rear, seating the GuideALink tabs of the caster frame in the rear GuideALink sockets of the cabinet.
Insert the previously removed quick-release pins to secure the caster frame.
Lift the other end of the caster frame, and secure with the previously removed quick-release pins.
Lower the array until the caster frame wheels contact the working surface.
For the cabinets to be removed, disconnect all cabling and release any strain reliefs.
For the bottom cabinet to remain suspended, remove the lower, front, and rear quick-release pins.
Note
Small adjustments of the hoists may be necessary to relieve tension or compression of the GuideALinks and quick-release pins.
For the top cabinet to be removed, remove the upper, front, and rear quick-release pins - GuideALinks will retract
Reinsert the previously removed quick-release pins.
Prepare the stack to be transported.
Caution
When 2100-LFC cabinets are stacked on caster frames, the front and rear GuideALinks of each cabinet should be extended and secured in place with quick-release pins connecting each cabinet of the stack.
Do not transport the cabinets with the GuideALinks of the top cabinet extended to prevent damage while transporting.
Move the disconnected cabinets away from the work area to a safe location.
Open the flap of the 2 or 3-high cover and slide over the top of the stacked cabinets.
Repeat steps 1-8 for additional stacks of cabinets.
Transporting MTG-2100 on Cabinets
When transporting an MTG-2100 Grid on a stack of one or two cabinets, use the front and rear GuideALinks to secure the grid to the top cabinet. This is the same configuration of the GuideALinks as when the array is suspended.
GuideALinks Extended and Secured with Quick-Release Pins
Caution
Do not transport 3-high stacks of 2100-LFC with the MTG-2100 Grid on top. This exceeds the safety limits for tip-over, which may cause injury.
