About the network
function
The network function lets you divide the audio
signal into different frequency bands, and
then reproduce each of them through sepa-
rate speaker units.
You can then make precise adjustments to the
reproduced frequency band (with a low-pass
filter or high-pass filter), level, phase and other
parameters to match the characteristics of
each speaker unit.
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.

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 units 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 the L LPF cut-off fre-
quency high, bass sound is separated so
that it appears to come from the rear. You
are recommended to set the L 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 the M HPF or H HPF cut-off
frequency is set lower than required, strong
bass signal input may damage the speaker.
