MLA Flying Grid
The MLA flying Grid is the principal system for deployment of MLA systems. When used with a two point suspension system it
can be used to fly up to 24 MLA or 15 MLX or a maximum of 6 MLX with 12 MLA flown below in a combination array (note that
this configuration requires two grids). The grid features a central spine which allows single point rigging of up to 10 MLA.
The grid is also used for ground stacking up to 6 MLA. This can be either directly on the ground or on top of an MLX sub to which
the grid can be attached for additional stability.
The grid has an inclinometer sensor attached with an XLR output for connection via a weatherproof XLR cable (as supplied with
all systems in lengths of 35m) to the Inclinometer reader for extremely precise adjustment of the array angle. The reader is
calibrated to the sensor and both are given a unique number to ensure that they are always used as a matched pair. The
calibration is to 0.1⁰. Never mix sensors and reader; you will not get accurate results. We recommend re
-calibrating the
inclinometer system annually to ensure consistent accuracy which is crucial to ensuring that an array covers the area you intend.
A large MLA system could comfortably cover distances of over 150m and an inaccuracy of a fraction of a degree could make a
difference of 20 to 30m at the furthest point of the coverage.

Calibration
There are two stages to calibrate the inclinometer system. First it is necessary to match the reading to an accurate test reference
clinometer, then to ensure that the span is correct by checking the adjustment with the grid at a large angle. Note that all
calibration is done to the reader, there is no adjustment required whatsoever to the sensor mounted on the grid
The Test reference level must of course be highly accurate and calibrated; it should be capable of measuring to at least a
resolution on 0.1⁰.
