Pioneer SUPER TUNERIII DEH-P8650MP - Manual (Page 47)

Level
The difference in reproduced levels between
speaker units can be corrected.
Slope
Adjusting the HPF/LPF slope (filter attenuation
slope) lets you adjust the continuity ofsound
between speaker units.
! The slope indicates the number ofdecibels
(dB) the signal is attenuated when the fre-
quency is one octave higher (lower) (Unit:
dB/oct.). The steeper the slope, the more
the signal is attenuated.
Phase
You can switch phase (normal, reverse) for
each speaker units input signal. When the
continuity ofsound between speakers is im-
precise, try switching phase. This may improve
the continuity ofsound between speakers.
Points concerningnetwork
adjustments
Cut-off frequency adjustment
! With the low-range speaker installed in the
rear tray, ifyou set Low LPF cut-off fre-
quency high, bass sound is separated so
that it appears to come from the rear. You
are recommended to set Low LPF cut-off
frequency to 100 Hz or lower.
! The maximum input power setting for mid-
dle- and high-range speakers is usually
lower than that for low-range speakers. Re-
member that if Mid HPF or High HPF cut-
off frequency is set lower than required,
strong bass signal input may damage the
speaker.
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
! Ifyou 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.
! Ifyou 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.
! Ifyou 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.

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