Connecting Each Speaker with One Pair of Speaker Wires Only With all the gold jumpers in place (see Diagram # 1), simply connect any of the red (+) terminals of each speaker to the red (+) terminal of its channel on your amplifier or receiver, and any of the black (-) terminals of each speaker to the black (-) terminal of its channel on your amplifier or receiver. It is essential that both speakers be connected in the same way (in phase) to its own channel of the amplifier. If you experience a great lack of bass, it is likely that one speaker is out of phase with the other. If you have a Dolby Digital system, "tell" your bass management system that you have "Large" left and right front speakers and "No" subwoofer. The base management system will then send the LFE .1 channel signal into the left and right channels, and it will be reproduced by the subwoofers in your BP7000SC/ BP7001SCs, giving you all the benefits of Dolby Digital and the discrete LFE signal. When the speakers are hooked up using simply one set of speaker wire per speaker (with no separate low level input for the subwoofer section), a special circuit takes an infinitesimally small signal from the speaker level input and converts it to a low-level signal which then drives the subwoofer power amp. + - Left Right Power Amplifier or Receiver Diagram # 1: Connecting Each Speaker with One Pair of Speaker Wires Only 7
