12.2 - FIL TER 1 - ARRA Y SIZE COMPENSA TION
Filter 1 is used to correct for LF/MF buildup when the array size/shape differ from that for which the factory preset was designed. LF
adjustments should be applied to all cabinets within the array; therefore, filter 1 is automatically applied globally. Filter 1 is a continuously
variable low-shelving filter, and 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 is used to compensate for atmospheric conditions due to large variations in temperature and humidity, which can have an impact
on 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 for
artistic purposes to adjust overall system tonal balance.
12.4 - FIL TER 3 - HF THROW DIST ANCE COMPENSA TION
Filter 3, along with gain shading, 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 close to an array and increase HF energy to areas further away, where air absorption has a bigger impact.
12.5 - FIL TER 4 & 5 - USER PEQ 1 & 2
Filters 4 and 5 are User PEQs, which can be applied to individual circuit groups. The Frequency and Q parameters are not linked across
circuits and, for this reason, it is recommended that User PEQ 1 & 2 are used only for moderate gain changes of frequencies above 1kHz.
