●Parametric equalizer mode <P.EQ>

The sound field can be adjusted by the P.EQ of five bands. For details on P.EQ adjustment, see

Bands 1 to 3: Select from the range 50 Hz to 20 kHz (1/3 octave steps, 27 points)

Bands 4 and 5: Select from the range 630 Hz to 20 kHz (1/3 octave steps, 16 points)

• Gain adjustment (GAIN)

Gain (output level) can be adjusted within the

range -12 dB to +12 dB.

About Q-curve

The following figure and the table show the relationship between center frequency, gain and Q-curve.

When a large numerical value is set, the Q- curve becomes sharper, and when a small numerical value is set, the Q-curve becomes gentler.

●About correction

When the frequency characteristics are measured by a measuring device, they do not need to be corrected if the frequency characteristics are flat (no ridges or valleys in the frequency waveform). However, frequency characteristics sometimes partially rise up or fall down. If this happens, create a frequency curve of inverse characteristics matched to the center frequency of the ridges or valleys in the frequency waveform. This corrects the frequency characteristics so that they are flat.

"Correction" is the process or making frequency characteristics as flat as possible.

Flat frequency characteristics can be made by selecting a Q-curve inverted to the frequency curve to be corrected.

8.Hold down the [s] button for about 1 second. You will hear a short high-pitched sound, and the filter settings, time alignment settings and P.EQ settings are saved to the memory (1 to 3) selected in step 6.

9.Press the [ADJ] button to return to the previous mode.

●To call up saved settings

At step 7, press the [s] button, and hold down the [s] button for about 1 second when "LOAD?" is displayed.

You will hear a short high-pitched sound, and the settings are called up. Press the [ADJ] button to return to the previous mode.

∗When the Equalizer mode is set to "BASS/TREB", the P.EQ settings that are called up are reflected when the Equalizer mode setting is changed to "P.EQ".

●About settings after a reset

When the [RESET] button is pressed to reset this unit, all settings set here disappear. Make a note of the settings in the Sound Setup Memo (page 34) to make these settings again after a reset.

Setting the sub-woofer/non-fader (SUB-WOOFER/NON-FADER)

Set to "ST" (stereo) or "MONO" (monaural) when a sub-woofer/non-fader is connected. There is no output when "OFF" is set.

* The factory default setting is "ST".

1.Press the [ADJ] button.

2.Press the [] or [] button to select "SUB- WOOFER" or "NON-FADER".

∗Select "SUB-WOOFER" when the Audio mode is the Standard mode or the Multi mode, and "NON-FADER" when the Audio mode is Direct mode.

3.Press the [] or [] button to select "ST" (stereo), "MONO" (monaural) or "OFF".

4.Press the [ADJ] button to return to the previous mode.
