Audio Adjustments Section 13 English Adjustable parameters The network function enables adjustment of the following parameters. Make adjustments in line with the reproduced frequency band and characteristics of each connected speaker unit. Level (dB) Reproduced frequency band Level Pass Slope (dB/oct.) Cut-off frequency of HPF Frequency (Hz) Cut-off frequency of LPF Reproduced frequency band Adjusting the HPF (high-pass filter) or LPF (low-pass filter) cut-off frequency lets you set the reproduced frequency band for each speaker unit. ! The HPF cuts frequencies (low) below the set frequency, letting high frequencies through. ! The LPF cuts frequencies (high) above the set frequency, letting low frequencies through. 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 of sound between speaker units. ! The slope indicates the number of decibels (dB) the signal is attenuated when the frequency 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 unit's input signal. When the continuity of sound between speakers is imprecise, try switching phase. This may improve the continuity of sound between speakers. Points concerning network adjustments Cut-off frequency adjustment ! With the low-range speaker installed in the rear tray, if you set Low LPF cut-off frequency 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 middle- and high-range speakers is usually lower than that for low-range speakers. Remember that if Mid HPF or HighHPF cutoff frequency is set lower than required, strong bass signal input may damage the speaker. Level adjustment The basic frequencies of many musical instruments are in the middle range. First perform middle-range level adjustment, followed by high-range and then low-range level adjustment in that order. Slope adjustment ! If you set a small absolute value for the slope (for a gentle slope), interference between adjacent speaker units can easily result 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. En 59

Adjustable parameters
The network function enables adjustment of
the following parameters. Make adjustments
in line with the reproduced frequency band
and characteristics of each connected speaker
unit.

Cut-off frequency
of HPF
Reproduced frequency band
Adjusting the HPF (high-pass filter) or LPF
(low-pass filter) cut-off frequency lets you set
the reproduced frequency band for each
speaker unit.
!
The HPF cuts frequencies (low) below the
set frequency, letting high frequencies
through.
!
The LPF cuts frequencies (high) above the
set frequency, letting low frequencies
through.
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 of sound
between speaker units.
!
The slope indicates the number of decibels
(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 unit
’
s input signal. When the
continuity of sound between speakers is im-
precise, try switching phase. This may improve
the continuity of sound between speakers.
Points concerning network
adjustments
Cut-off frequency adjustment
!
With the low-range speaker installed in the
rear tray, if you 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
HighHPF
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
!
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.
