A
array A group of flown loudspeakers that has been configured to produce optimum sound pressure level
(SPL) and coverage in a particular venue.
B
block A group of loudspeakers from an array that has been broken down into convenient-sized groups for
transport.
bridle A method of using two steel cables connected to two lifting points on an array’s top grid, brought
together to a common point and attached to a lifting motor.

chain bag or bucket A place where the chain from lift motors is stored as the chain moves through the lift motor.
D
dead hang A lifting configuration where the lifting motors are connected directly to the lifting points on the MTD-
3D Top Grid without the use of a bridle.

weight and other factors such as acceleration, bounce, and startup forces.
F
fly The process of lifting an array into position in a venue.

L
laser level A device used by audio technicians to determine an array’s site angle during setup or at final trim
position. It also has readout illumination and can be set to relative angles.
