If you set the slope to 0 dB/oct. (
Pass
), the
audio signal bypasses the filter, so the filter
does not have an effect.
Phase adjustment
When the cross-over point value for filters on
both sides is set to
–
12 dB/oct., the phase is
reversed 180 degrees at the filter cut-off fre-
quency. In this case, reversing the phase as-
sures improved sound continuity.
