SYSTEM TUNING
To get the most from any line array, it needs setting up correctly. Without tuning and refining, the
system will not deliver to its full potential.
The system not only needs to be tuned to the room or venue, but the individual elements of the
array need to be tuned to work perfectly in relation to each other. By following the 4 'Tuning Tips'
you can improve the overall performance of your line array.
1. ARRAY SCALING
As elements are combined, the lower frequencies are proportionally increased. Therefore, when
more elements are used, more LF reduction is needed.
2 to 4 elements
5 to 8 elements
8 elements or more
2. RANGE EQ
Higher frequencies are reduced in energy by distance. This is as a result of air absorption. To
compensate for this energy loss over distance, Peaking or Bell filters should be used.
The amount of energy absorbed by air also changes as a result of humidity. So always think about
this constantly variable loss (or comparative gain) of HF energy.
More HF EQ needed due to distance
