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 wireis 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 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 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 promptly ship one to you of

suitable length at no charge.
