Using the speaker level inputs

If you are using a receiver which does not have a sub- woofer output or line level outputs (pre-outs), you can connect its speaker outputs to the subwoofer’s speaker- level inputs. The front speakers can still be connected to your receiver.

DIM - STANDBY BRIGHT - ON

The subwoofer’s internal ampliÞer supplies the power to reproduce the low frequency range. It receives a sample of the signal going to your front speakers. (An insigniÞcant frac- tion of your receiver’s power is transferred to the subwoofer).

There is no

 

need to use the

If you are using the line level inputs and there is a excessive amount of noise or hum present, using the speaker level inputs may yield a lower background noise level.

TO FRONT SPEAKERS

Your receiver MUST have common grounded outputs, or it will be dam- aged if connected to the subwoof- er’s speaker level inputs.
