Depending on whether you are using one or two subwoofers, connecting your satellites can be
accomplished in one of two ways. If you are using a single subwoofer with a pair of satellites,
connect them as shown in Figure 7.
If you are using two subwoofers as a stereo pair with a pair of satellites, connect them as shown
in Figure 8.

The subwoofer has a variable frequency control that can be used to block unwanted
frequencies (between 50 – 150Hz) from being reproduced by the subwoofer. Where you set
this control depends on the low-frequency capabilities of your satellite speakers. Adjust this
knob to the lowest frequency that your satellite speakers were designed to reproduce (refer to
Operation, step 8).
