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.

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"

Frequency band played back mainly by the speaker

2kHz (2kHz to 20kHz)

20kHz

Frequency set on the low-pass filter

Frequency set on the high-pass filter

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"

Frequency band played back

2kHz mainly by the speaker (2kHz onwards)

Frequency set on the high-pass filter

When HPF is set to "THROUGH" and LPF is set to "20kHz"

Frequency band played back mainly by the speaker (to 20 kHz)

20kHz

The following figure shows the factory default settings for filter frequencies in the Multi mode.

Frequency band played back mainly by HIGH (2 kHz onwards)

Frequency band played back mainly by MID (500 Hz to 2 kHz)

Frequency band played back

mainly by LOW (80 kHz to 500 Hz)

Frequency band played back mainly by SUB-W (to 80 kHz)

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.

About filter slope (SLP)

18 DRZ9255

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.
