About
The preset described in "Create A Test Preset", page 14 uses a bass management con
fi
guration and several loudspeaker groups
with differing acoustic properties. Therefore it is advisable to apply IIR-Filters to individual system components for leveling, separat-
ing low frequency and full-range components and equalization (Find more information about IIR-
fi
lters in "Filter Creation", page 23).
