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
outputted 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).
1 Use MULTI-CONTROL to select NW 1.
NW 1 appears in the display.
2 Push MULTI-CONTROL left or right to
select the speaker unit (filter) to be ad-
justed.
Each time MULTI-CONTROL is pushed left or
right, the speaker unit (filter) is selected in the
following order:
Low LPF (low-range speaker LPF)—Mid HPF
(middle-range speaker HPF)—Mid LPF (mid-
dle-range speaker LPF)—HighHPF (high-range
speaker HPF)
3 Push and hold MULTI-CONTROL down
to mute the selected speaker unit (filter).
MUTE blinks in the display.
# Tocancel the muting, push MULTI-CONTROL
up.
