MLA Compact Flying Grid

The MLA Compact flying Grid is supplied in pairs with all MLA Compact systems. It enables flying of up to 24 MLA Compact when
using a two point lift, or 12 enclosures from a single point. Ground stack systems of up to 6 Compact can also be employed using
the same grid with the addition of ground stack bars which as supplied as part of the system.
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 Compact system could comfortably cover distances of up to 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.
The Flying grids are supplied flightcased in pairs with the following accessories;-
1x CAR00040
2x ASF20032
2x SEN00002
2x ASF20042
2x ASF20044
4x HTK300
2x HAM09107
2x HAM09106

Calibration

The Calibration for the MLA Compact Flying frame is exactly the same procedure as that for the MLA Flying grid, please see the
relevant chapter for details.
Fortunately the MLA Compact Flying Frame is not anything like as heavy as the MLA flying grid but caution should still be taken
when angling the grid to check the calibration at steep angles. Make sure it is adequately supported before taking measurements;
the grid could still easily cause injury if it falls.
