9 Turn the Rotary encoder to select a speaker to be set.

10 Press the 1 (TIME ; DN) or 2 (TIME UP :) to adjust the time revision value.

11 Press 3 (0°) or 4 (180°) to switch phase.

12 Repeat steps 9 to 11 to adjust other channels.

13 Press 7 (RETURN) to return to the previous display.

When the speaker is set to the “OFF” mode, the TCR for that speaker cannot be set. Refer to “Setting the Speakers” (page 44).

Graphic Equalizer Adjustments

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.

1 Check that the Defeat mode is off.

When the speaker is set to the “OFF” mode, the graphic equalizer for that speaker cannot be set. Refer to “Setting the Speakers” (page 45).

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.

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.

1 Check that Defeat mode is off.

2 Press SOURCE/POWER.

The main menu is displayed.

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 damage the speakers.

When the parametric EQ is adjusted, the adjustment for graphic EQ becomes ineffective.
