15. esigned using Shape Designer software you can effectively optimise the array depending on the environment and the application by driving it using different DSP presets stored onboard Typically arrays are divided in two or three zones depending the design and size of the array To optimise and EQ the array different strategies are used for high frequencies long throws and short throws and low frequencies The longer the distance the greater the attenuation at high frequencies Generally high frequencies need a correction to compensate for energy lost over distance the correction needed is usually proportional to the distance and high frequency air absorption In the near to mid field the air absorption is not nearly as critical in this zone high frequencies need little additional correction In the next figure is shown the equalization that corresponds to HF settings for NEAR and FAR HIGH FREQUENCY EQUALIZATION STRATEGIES 20 While wave guides provide isolated control over various mid to high frequency coverage areas the low frequency section of a HDL array still requires mutual coupling with equal amplitude and phase to achieve better directionality Low frequency directionality is less dependent on the array s relative splay angles and more dependent on the number of elements of the array At low frequencies the more elements in the array the longer the array the more
