The BU-1 subwoofer may be connected to your system using the HIGH-LEVEL INPUTS (4) on
the plate located on the rear panel of the subwoofer. Use ordinary lamp cord maintaining
proper polarity (+ to + and – to –). Attach the lamp cord to the left and right HIGH-LEVEL
INPUTS on the subwoofer and the other ends to the proper left and right OUTPUTS on your
amplifier or receiver (see Figure 5).
If you plan to use two subwoofers (one for the left and the other for the right channel) connect
wires from the left and right OUTPUT on your power amplifier or receiver and attach the other
ends to the corresponding HIGH-LEVEL INPUTS on each subwoofer. Observe polarity
(see Figure 6).
