Controls
Volume (on front panel):
Adjusts the sound level of the subwoofer. A typical setting is around
11 o’clock.
Crossover (Hz):
Adjusts the frequency of the low-pass filter for the
subwoofer. This control is inactive when using the
“bypass crossover
control”
input jack.
Polarity (0° or 180°):
Selects regular (0°) or inverted (180°) polarity for the subwoofer.
Set this switch to provide the fullest, most dynamic bass. The effect of phase will be
most audible on low-frequency percussion instruments or music with a continuously
repeating bass line.
Power light and power status:
The power light turns on whenever the PV500 is plugged into an
electrical outlet. The PV500’s auto-on circuitry turns the subwoofer on when a signal is presented, and
turns it off if no signal is detected.
NOTE:
Power is always supplied to the subwoofer electronics unless
it is unplugged. The auto-on circuitry only activates or deactivates the power amplifier.
Connecting the Subwoofer to Stereo or Dolby

Systems
For stereo or Dolby Pro Logic systems, the easiest method is to use the same speaker wire connections as shown on page 5.
You may also use the “sub out” connection from your receiver to the input on the subwoofer marked
use crossover
control.
When using speaker wire or the
use crossover control
input, the subwoofer’s built-in crossover is engaged. As a
starting point, set the crossover control on the subwoofer about 10Hz higher than the lower limit of your main speakers’
bass response (for Boston Acoustics front speakers, refer to the included “Optimal Crossover Settings...”sheet). Fine-
tune the crossover setting by ear for the smoothest blend with your main speakers. The best setting of the crossover
control will depend on speaker placement and personal preference.
