Speaker Level - Boston Acoustics CPS 10Wi Owner's Manual

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
RCA line input or output on your receiver
(see diagram). The proper ground cable for
this application should consist of two male
RCA plugs that have their negative outside
terminals (or "sleeve") connected to each
other by any length of single conductor
copper cable. The inside positive (or "pin")
terminals should not be wired in either plug.
