About filter frequency (fc)
The filter (high-pass filter and low-pass filter)
frequency can be set for each speaker
according to the characteristics of the speaker.
Set the lower limit frequency to be played back
mainly on that speaker on the high-pass filter
(simply called "HPF" from here on), and set the
upper limit frequency on the low-pass filter
(simply called "LPF" from here on).
When HPF is set to "2kHz" and LPF is set to
"20kHz"
When the filter is set to "THROUGH", the setting
for that filter is disabled, and all frequencies are
played back.
When HPF is set to "2kHz" and LPF is set to
"THROUGH"
When HPF is set to "THROUGH" and LPF is set
to "20kHz"
Operations Common to Each Mode
About the Standard mode and Multi
mode
These two modes can be used to make the
following various sound adjustments for playing
back music sources:
• Setting of the filter (high-pass filter and low-pass
filter) frequency for each speaker
• Tone adjustment by P.EQ (parametric equalizer) or
BASS/TREB (bass/treble)
• Position setting by TIME ALIGN (time alignment)
• Sub-woofer "ST" (stereo), "MONO" (monaural) and
"OFF"
Select the Standard mode or the Multi mode
according to your speaker configuration.
• Standard mode: FRONT(2ch) + FRONT(2ch)
+ REAR(2ch) +
SUB-W(2ch)
• Multi mode:
HIGH(2ch) + MID(2ch) +
LOW(2ch) + SUB-W(2ch)
●About filter settings
The following filters can be set for each speaker:
• Filter frequency (fc)
• Filter slope (SLP)
• Gain (G)
• Phase (PHASE)
Notes:
• Input of a low-band signal to the tweeter may
cause a malfunction.
2kHz 20kHz
Frequency band played back
mainly by the speaker
(2kHz to 20kHz)
Frequency set on the high-pass filter
Frequency set on the low-pass filter
2kHz
Frequency band played back
mainly by the speaker (2kHz onwards)
Frequency set on the high-pass filter
20kHz
Frequency band played back
mainly by the speaker (to 20 kHz)
Frequency set on the low-pass filter
Operations Common to Each Mode
80Hz 500Hz
2kHz
Frequency band played back
mainly by SUB-W (to 80 kHz)
Frequency band played back
mainly by LOW (80 kHz to 500 Hz)
Frequency band played back mainly
by MID (500 Hz to 2 kHz)
Frequency band played back mainly
by HIGH (2 kHz onwards)
About filter slope (SLP)
The following figure shows the factory default
settings for filter frequencies in the Multi mode.
The filter frequency ranges that can be set vary
according to the speaker. The following table
shows these ranges.
Note, however, that the frequencies are selected
from the value (1/3 octave steps) currently set
on this unit.
-: THROUGH (fixed) cannot be changed.
Effectiveness can be adjusted for each filter
(HPF or LPF).
"-12dB/oct" is more effective than "-6dB/oct" and
"-18dB/oct" is much more effective.
The factory default setting is "-12dB/oct". Try
switching between "-6dB/oct", "-12dB/oct" and "-
18dB/oct " and select the setting that sounds
most natural to you.
