How Adaptive Systems Handle Horizontal Coverage with Multiple Columns
One of the major advantages of Adaptive Systems is the integration of multiple columns for smooth,
consistent, precise horizontal coverage at all frequencies.
With traditional line array systems, multiple horizontal arrays (i.e. mains and out-fills) are physically
separated and independent. During setup, engineers choose a location to align them, accepting the
consequences of misalignment at other locations. With Adaptive Systems, tight-packed multi-column
arrays are fully integrated, working together as a singular entity to achieve a coverage solution
throughout the entire horizontal and vertical coverage range of the entire array, not just each
individual column.
Great benefit of this can be seen at lower frequencies, where the horizontal energy of an array is
adjusted to benefit the greatest number of seats possible.
In the below example, an array of three columns of 4 Anya modules each clearly can be seen to
manipulate the low-frequency pattern to provide optimal coverage of the venue, allocating the
available low-frequency energy from all three columns down the long-throw side of the coverage area.
No physical changes are made between the two examples – it is only the enabling and disabling of the
LF correction algorithm.
Above, an array without LF correction – Low-frequency energy is directed through centerline of array,
diagonally. This is the ‘natural’ response of this array geometry.
Above, an array with LF correction to shift the low-frequency energy towards the majority of the
audience (on the right side of the venue), reducing excess bass energy behind the array and in the side
audience areas. No physical changes have been made to produce this benefit – it is an inherent
component of how Adaptive Systems work.
