Level adjustment
The basic frequencies of many musical instru-
ments are in the middle range. First perform
middle-range level adjustment, followed by
high-range and then low-range level adjust-
ment in that order.
Slope adjustment
! If you set a small absolute value for the
slope (for a gentle slope), interference be-
tween adjacent speaker units can easily re-
sult in degraded frequency response.
! If you set a large absolute value for the
slope (for a steep slope), continuity of
sound between speaker units is degraded,
and sounds appear to be separated.
! 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.

Muting the speaker unit (filter)
You can mute each speaker unit (filter). When
a speaker unit (filter) is muted, no sound is
output from that speaker.
! If you mute the selected speaker unit (fil-
ter), MUTE blinks and no adjustments are
possible.
! Even if any speaker unit (filter) is muted,
you can adjust the parameters for other
speaker units (filters).
