CAUTION:
When suspending MG-MINA/LINA/750-LFC arrays from two motors, make sure each motor and
the ceiling pickup point (above the hook) are rated to hold the total weight of the grid and array.
MG-MINA/LINA/750-LFC Pickup Configurations with One Motor
The following examples show pickup configurations with a single motor. While single motor configurations are supported, it
is more difficult to change the tilt of the grid with these configuration when compared to configurations with two motors.
CAUTION:
When suspending MG-MINA/LINA/750-LFC arrays from a single motor, make sure the motor and
ceiling pickup point (above the hook) are rated to hold the total weight of the grid and array.
TIP:
MAPP’s Center of Gravity feature lets you easily determine the appropriate center pickup hole of the
MG-MINA/LINA/750-LFC. For more information, see “Estimating the Center Pickup Point with MAPP” on
page 31.
MAPP SYSTEM DESIGN TOOL AND RIGGING INFORMATION
MAPP is a powerful, cross-platform application for accurately predicting the coverage pattern, frequency response, impulse
response, and maximum SPL output of single or arrayed Meyer Sound loudspeakers. Residing on your local computer, the
MAPP client allows configuration of Meyer Sound loudspeaker systems and definition of the environment in which they will
operate, including air temperature, pressure, and humidity.
MAPP System Design Tool provides a wealth of rigging information for loudspeaker arrays by automatically calculating the
following values for specific array configurations:
•
Total weight of array
•
Height and depth of array
•
Array’s center of gravity (required for determining the center pickup point and maximum uptilt and downtilt)
•
Load distribution for front and rear attachment points
