MLD

The MLD is the accompanying downfill enclosure to complement the MLA. It is designed primarily to be used at the bottom of
an array using either a single MLD or a pair. Display 2.1 does not support any more than two MLD in an array. As a downfill box
the dispersion is optimised for a wider coverage so the MLD has a horizontal coverage of 120⁰ compared to MLA's 90⁰, and a
vertical coverage of 20⁰ compared to MLA's 7.5.

Mechanical Design

The MLD uses the same mechanical principals as the MLA and obviously has exactly the same width so it can be rigged with MLA.
The cabinet is slightly taller at 454mm (17.9") to allow for the greater vertical coverage. The same rugged 18mm ply construction
with PU weather-proof finish and black powder coated steel rigging is employed as MLA

Rigging

The rigging on the MLD is designed to complement the MLA. The front rigging brackets operate in exactly the same way with the
rigging bar running the full height of the cabinet and dropping down when the flying pin is removed from the central sowing
position. The rear bracket is slightly shorter than the MLA as the cabinet is not as tall at the back; it has a more exaggerated
trapezoidal shape as a result of the greater vertical coverage angle.
