If Speaker Wire Connections Cause the Subwoofer to Hum

Certain receivers use speaker grounding circuits that may be incompatible with 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 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.

If you do not wish to make your own use either RCA jack 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.
