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 external 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 outside terminals (or “sleeve”) connected to each other by any length of single conductor copper cable. The inside posi-
tive (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 (see below) and we
will promptly ship one to you of suitable length at no charge.
