The graphic equalizer allows you to modify the sound using 31 bands
each for the front (left and right), rear (left and right) and center
speakers. An additional 10 bands are available for the subwoofer. This
allows you to customize the sound to suit your taste.

• 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.

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.
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.

Conditions:
Distance between farthest speaker and listening position:
2.25 m (88-3/4")
Distance between front left speaker and listening position:
0.5 m (20")
Calculation:
L = 2.25 m (88-3/4") – 0.5 m (20")= 1.75 m (68-3/4")
Compensation time = 1.75 ÷ 343 x 1000 = 5.1 (ms)

channels.

Different adjustment values can be set for the left and
