12.2 FIL TER 1 - ARRA Y SIZE COMPENSA TION
Filter 1 is used to correct for LF/MF buildup when the array size or shape differ from that for which the factory preset was designed.
Filter 1 is automatically applied globally to provide uniform LF adjustments to all cabinets in the array. Filter 1 is a continuously variable
low-shelving filter. Its parameters (corner frequency and slope) are adjusted based on the applied gain value. Array buildup is different
for each configuration, and Filter 1 is optimized to correct for this effect using only one parameter (Gain).
12.3 FIL TER 2 - A TMOSPHERIC ABSORPTION COMPENSA TION
Filter 2 compensates for atmospheric conditions such as large variations in temperature and humidity, which can impact overall HF
energy. Filter 2 is applied globally and can be used to quickly brighten or darken an array. This filter can also be used to adjust overall
system tonal balance to taste.
12.4 FIL TER 3 - HF THROW DIST ANCE COMPENSA TION
Filter 3 is used to correct for distance offsets between different sections of an array. The Type, Frequency, and Q parameters are linked
across the entire array, but the Gain parameter is adjustable per circuit group. This filter can be used to reduce HF energy delivered close
to an array and increase HF energy reaching further areas, where air absorption has a bigger impact.
12.5 FIL TERS 4 & 5 - USER PEQ 1 & 2
Filters 4 and 5 are User parametric EQs, which can be applied to individual circuit groups. As the Frequency and Q parameters are not
linked across circuits, it is recommended that User PEQ 1 & 2 be used only for moderate gain changes of frequencies above 1kHz.
