Boston Acoustics Complete Guide to Connecting PV700 and PV900 Subwoofers

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”.

CAUTION: Disconnect supply cord before replacing fuse. For continued protection against risk of fire, replace only with same type fuse.

SUBWOOFER OUT

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.
