Advanced use of AutoPhase
AutoPhase uses the selected Bass Management Filter frequency setting together with the selected
monitor. The purpose of AutoPhase is to align the subwoofer phase with the reference monitor so
that the frequency response across the bass management crossover is flat.
Acoustical reasons for selecting the crossover frequency
Select a crossover frequency for the group that makes acoustical sense. A good crossover
frequency is one that shows good output from at least the subwoofer and the reference monitor.
Even better is when there is sufficient output from all monitors at the crossover frequency. The
output is sufficient when the level in the equalized frequency response is similar to the midrange
level and there is no notch in the frequency response close to the crossover frequency.
