AIR ABSORPTION COMPENSATION
Display 2.2 can compensate for the effects of air absorption which can have a very significant
effect on the upper frequency bands. The compensation is added in this section on the Coverage
page:
The fader bar adjusts the amount of compensation from zero to a maximum level. This is best
used for higher amounts where weather conditions are extreme or where you have particularly
long throws as the compensation will help ensure that higher frequencies are not lost. However,
be careful not to overdo it if not really necessary as you could run the risk of running out of
headroom in the upper frequency bands.
The Edit button brings up the window into which you can enter the necessary environmental
conditions:
If you un-check the air absorption there will be no compensation applied to the optimisation,
you can still enter the Temperature, Humidity and Pressure so if you need to create a new
optimisation including air absorption it is as quick and easy as checking the box. Be aware that
environmental conditions change drastically throughout the day! A 6.00 am load-in is going to
give very, very different readings compared to a packed, 8.00pm show with all lighting, smoke
machines and pyrotechnics going full tilt!
