CONNECTIONS Connecting to speaker output terminals of the amplifier 2 Select this method if your amplifier has no line output (pin jack) terminal. If your amplifier has two sets of front speaker output terminals and both terminals can output sound signals simultaneously. • Connect one set of front speaker output terminals of the amplifier to the INPUT 1 terminals of the subwoofer, and connect the other set of front speaker output terminals of the amplifier to the front speakers.
CONNECTIONS If your amplifier has only one set of front speaker output terminals. Connect the speaker output terminals of the amplifier to the INPUT 1 terminals of the subwoofer, and connect the OUTPUT terminals of the subwoofer to the front speakers.
CONNECTIONS Connecting to the INPUT 1/OUTPUT terminals of the subwoofer For connection, keep the speaker cables as short as possible. Do not bundle or roll up the excess part of the cables. If the connections are faulty, no sound will be heard from the subwoofer or the speakers, or both of them. Make sure that the + and – polarity markings of the speaker cables are observed and set correctly. If these cables are reversed, the sound will be unnatural and lack bass.
