Pioneer AVM-P9000 owner manual Selecting a Crossover Frequency, Correcting the Subwoofer’s Phase

Fine Adjusting Audio (Expert)

Selecting a Crossover Frequency

You can select a frequency, sounds under which are reproduced through the subwoofer.

If the installed speakers include one whose “Size” has been set “SMALL”, you can select a frequency, sounds under which are reproduced through a “LARGE” speaker or subwoofer.

1.Select “Cross Over” by moving the joystick.

“Cross Over” is highlighted in green.

2.Click the joystick.

Each click changes crossover frequency in the follow- ing order:

100 Hz = 200 Hz = 63 Hz

Note:

•Selecting a crossover frequency is to set a cut-off frequency of the subwoofer’s L.P.F. (low- pass filter) and that of the “SMALL” speaker’s H.P.F. (high-pass filter). Crossover frequency setting has no effect if the subwoofer is set “OFF” and any other speaker set “LARGE” or “OFF”.

Correcting the Subwoofer’s Phase

If trying to boost the bass output of the subwoofer doesn’t do much or rather makes you feel that bass gets further murky, this may indicate that the subwoofer’s output and bass content you hear over other speakers cancel each other out.

To remove this problem, try changing the phase setting for the subwoofer.

1.Select “SW Phase” by moving the joystick.

“SW Phase” is highlighted in green.

2.Click the joystick.

Each click toggles NORMAL and REVERSE.
