Using the speaker level inputs
If you are using a receiver which does not have a subwoofer output or line level outputs (pre- outs), you can connect its speaker outputs to the subwoofer’s
The subwoofer’s internal amplifier supplies the power to reproduce the low frequency range. It receives a sample of the signal going to your front speakers. (An insignificant fraction of your receiver’s power is transferred to the subwoofer).
There is no need to use the Speaker Level inputs if you are using a separate amplifier and preamplifier. Such systems are best connected using the Line Level inputs as shown in the previous diagrams.

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.
Your receiver MUST have common grounded outputs, or it will be damaged if connected to the subwoofer’s Speaker Level inputs.
