therefore quick to do and could easily be done between acts at a festival for example. This could be extremely useful if you have
done a number of optimisations for an outdoor space with different environmental conditions to compensate for the variation
in air absorbsion during the day as the conditions change from bright sunlight to cool evening. If you need to save or select
snapshots for several arrays simultaneously you would select the necessary arrays as already described, then use the Load or
Save Snapshots commands in the Edit menu, however if you just need to select snapshots in a single array you can do so using
the menu functions available by right clicking. Snapshot creation and recall will be covered in greater detail in a later chapter.

Defining Zones

By default every array is discovered as a single zone but from this menu any array can be divided into up to six zones which can
all be equalised and have their gain trimmed independently. Perhaps the most common use for this is to zone an MLD
independently from the rest of the array as there is often a requirement for the near-filed coverage to have quite different
equalisation. As an example, we will take a twelve cabinet array and divide it into three zones; the MLD, the lower six MLA and
the top five MLA.
First click on 'Define zones' in the right-click menu. Will see the following window;-
This shows a single zone of twelve cabinets, the total at the bottom is shown in green because it equals the numbers in all zones.
We now click 'Add' and an additional zone is added of one cabinet below the first. The upper zone has its quantity reduced to
eleven to maintain the total of twelve;-
Click 'Add' a second time, it is necessary to create the desired number of zones first and then modify the quantities in each zone.
New zones are always added below the previous and the position in which they are shown corresponds to the physical position
in the array;-
