If Speaker Wire Connections Cause the Subwoofer to Hum
Certain receivers use speaker grounding circuits that may be incompatible with the speaker level inputs of exter-
nal powered audio products, such as powered 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 the 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 theirnegative out-
side ter
minals (or “sleeve”) connected to each other by any length of single conductor copper cable. The inside
positive (or “pin”) terminals should not be wired or removed in either plug.
If you do not wish to make your own
grounding cable, please contact the
Boston Acoustics Customer Service
Department directly (next page) and
we will pr
omptly ship one to you of
suitable length at no charge.
