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.

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 "

" (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.
