frequencies; use with sources lacking suitable
filtering (most products without Dolby Digital
or DTS), or where manual control is desired. ** bypass crossover control: direct to woofer;
use with sources having built-in crossover

Connecting the Subwoofer to Digital Home Theater Systems
Digital 5.1, 6.1 and 7.1 home theater electronics dedicate one channel (the “.1”) to reproduce the special
low-frequency (LFE) information (such as explosions and thunder) contained in digitally-encoded soundtracks.
Select ”subwoofer-yes“ from your receiver’s set-up menu. Hooked up this way, the receiver’s amplifier is relieved of
having to reproduce the difficult low bass signals that can drive the receiver into audible distortion.
Use an RCA cable (not included), as shown, to connect your digital receiver’s subwoofer output to the subwoofer.
Connect the other end to the PV700 or PV900 jack labeled “bypass crossover control” underneath “line level in”.
Be sure to connect + to +
(red) and – to – (black
).
If you do not wish to run RCA cables to your subwoofer, you may use speaker wire to connect the subwoofer in parallel
with your main speakers (see diagram below). The subwoofer does not present any additional load to your receiver.
Select “subwoofer-no” from your receiver’s set-up menu. This sends the LFE signal to the main left and right speakers,
and thus, to the subwoofer. Consult your receiver’s owner’s manual for more details.
When using the speaker wire hookup, 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.
