OPTIMISATION

The Optimisation section is where the optimisation characteristics are defined. The splay
coefficients determine the priority given to either the target response or the leakage. The actual
numbers entered are not important, it is the ratio between them that determine how much
priority is given to each coefficient so if you want the Target coefficient to be twice as important
as Leakage you can enter '2' in Target and leave leakage as '1' or you could leave Target as '1'
and change Leakage to '0.5' the result would be exactly the same.
Allow Polish lets the software take a second run at refining the inter-cabinet angles after it has
completed the first pass. It re-starts the optimisation when it has completed the first attempt
with the angles it has already calculated as a starting point and further refines them to get the
best possible result. If you are in a rush you may want to disable this feature, particularly for very
large arrays which may take some time to optimise.
The Max Time is the time in seconds that the system will allow for the optimisation to run. For
the vast majority of systems the default setting of 600 seconds (10 minutes) will be more than
adequate, particularly when Display 2.2 is run on a high spec PC. With very large arrays in
complex venues you may need to increase this time to get the best optimisation assuming you
have the time at your disposal. If you don't have sufficient time the optimisation will time out
and you will see a warning suggesting that you increase the Maximum Time. You can however,
accept the angles it has calculated at any stage or even enter your own angles manually and the
Equalisation optimisation will work from these angles albeit with a slight compromise on the
system performance. Whilst some array angles may look strange to those used to working with
conventional line arrays, always trust the software! Multicellular systems are NOT line arrays so
don't try and use them in the same way.

Optimisation Progress

The Optimisation Progress shows the code trying all possible angles of the array cabinets in real
time as the optimisation is running. This is simply a reference so you can see that the software
is actually doing something!

Run the optimisation

Click on the Optimise button and the system will run through all possibly array angle configurations.
The drawing will show the array moving through the various positions and will be green:
