Equalizer adjustments

The PXI-H990 is equipped with a graphic equalizer and parametric equalizer. You can set the Equalizer to whatever values you want.

Graphic equalizer

The level of the front, rear and center channels can be adjusted separately for 31 bands and the subwoofer can be adjusted for 10 bands (a total of 206 bands) to achieve the desired sound field.

Parametric equalizer

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 these specific frequencies. Then, the bandwidth (Q) and level are fine-tuned, independ- ently, to make the necessary corrections. The parametric equalizer function is an advanced tool for serious audiophiles.

•This adjustment is easier when test signals such as pink noise are used. For information on test signals, consult your authorized Alpine dealer.

•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.

•Once the settings have been made, we recommend storing them in the memory. See page 93 for instructions.

•If you combine with a head unit (DVI-9990) or monitor (TMI-M990) (both sold sepa- rately), you can adjust the equalizer while viewing the adjusted contents on the monitor screen. (See “Equalizer adjustment (when DVI-9990/TMI-M990 is connected)”, page 99).

•MP3 and WMA recorded Discs with a sampling frequency of 32 kHz cannot be compen- sated above 16 kHz.
