Answer
As the size and total vertical coverage of an array is altered, the resulting change in low frequency (LF) energy output is not the same as the change in high-frequency (HF) output. In order to maintain consistent balance between LF and HF, array equalization filters are used. These shelving filters display varying amplitude and frequency. QSC’s AWARE™ (Automatic Wireless Array Recognition) technology provides the loudspeakers with the data that is required to select the appropriate equalization filter(s) for each specific deployment.
