Connecting to Electronics Without a Subwoofer Output

If the receiver in your system does not have a subwoofer or LFE output you can connect the CPS Wi subwoofer to a preamp output. Use a stereo RCA cable (not included) to connect the preamp outputs to the “L” and “R” Line Level inputs.

Adjusting the Crossover Control

When using the Line Level inputs (not the LFE 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. 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.

Speaker level

Use these high-level terminals with receivers that do not have subwoofer output. The speaker inputs accept both left and right channel speaker signals from your receiver. When using a home theater receiver, set the speaker type to “Large.”The large setting will produce a fuller sound.

Note

Certain receivers use speaker grounding circuits that may be incompatible with external powered audio products, such as pow- ered subwoofers. When speaker wire is used instead of line level cables, this incompatibility can result in an audible hum when the receiver is turned off or switched to a different speaker channel.

If this should happen with your Boston Acoustics subwoofer, you will need to make a ground cable and connect it to either RCA

line input on the subwoofer and any unused
