Select the frequency by turning the Rotary
encoder, then press MODE.
Adjustable frequency:
FRONT/REAR/CENTER: 20Hz - 20kHz (in 1/3 octave steps)
SUBWOOFER:
7
Adjust the level (LEVEL) (±9dB 1dB step) by turning
the Rotary encoder, then press MODE.
8
To adjust other frequencies, repeat steps 6 and 7.
9
To adjust other channels, repeat steps 5 to 8.
10
When the setting is complete, press and hold MUTE
for at least 2 seconds.
The unit returns to the normal mode.
• When the speaker is set to the "OFF" mode, the level of the graphic
equalizer for that speaker cannot be adjusted. Refer to "Setting the
Speakers" (page 36).
• Check the playable frequency ranges of the connected speakers
before making the equalizer adjustments. If the speaker's playable
frequency range is 55 Hz to 30 kHz, for example, adjusting the 40 Hz
or 20 Hz band has no effect. Additionally, you may overload and
damage the speakers.
• When graphic EQ is adjusted, the adjustment for parametric EQ
becomes ineffective.
• When the setting is complete, it is recommended to store the setting
contents. For storing, refer to page 43.

Parametric Equalizer Adjustments

The frequency bands of the graphic equalizer are fixed. This makes it
very difficult to correct for undesired peaks and dips at specific
frequencies. The parametric equalizer's center frequency can be tuned
to these specific frequencies. Then, the bandwidth (Q) and level are
fine-tuned, independently, to make the necessary corrections. The
parametric equalizer function is an advanced tool for serious
audiophiles.

• When the speaker is set to the "OFF" mode, the parametric
equalizer for that speaker cannot be set. Refer to "Setting the

• It is not possible to adjust the frequencies of adjacent bands within 7
steps.
• Check the playable frequency ranges of the connected speakers
before making the equalizer adjustments. If the speaker's playable
frequency range is 55 Hz to 30 kHz, for example, adjusting the 40 Hz
or 20 Hz band has no effect. Additionally, you may overload and
