Boston Acoustics PV700, PV900 manual Controls

Connecting the Subwoofer to Stereo or Dolby® Pro Logic® 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.

Main power switch Completely turns all power to the amplifier either on or off and over-rides the power mode switch. This switch must be turned on before setting the power mode switch (see next page).

Volume (on front panel) Adjusts the sound level of the subwoofer. A typical setting is around 11:00 o’clock, as shown.

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.
