IMPORTANT!

Figure 8. Method when connecting two subwoofers to satellites.

Depending on whether you are using one or two BU-1 subwoofers, connecting your satellites can be accomplished in one of two ways. If you are using a single BU-1 with a pair of satellites, connect them as shown in Figure 7.

If you are using two BU-1 subwoofers as a stereo pair with a pair of satellites, connect them as shown in Figure 8.

The BU-1 subwoofer does not have a built-in passive crossover which would roll off your satellites’ lower frequencies. However, the BU-1 does have 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).
