CONNECTIONS TO YOUR AMPLIFIER This speaker system is capable of standard connections and bi-wiring connections. Before making connections, make sure that the amplifier is switched off. Leave the short bars in place when connecting. Remove the short bars before connecting. Tweeter terminals Tighten Loosen Short bar + - Speaker (R) + Speaker (L) Woofer terminals - Speaker (R) Speaker (L) Speaker (R) Speaker (L) Speakers output terminals of the amplifier SPEAKERS R +- L A -+ B SPEAKERS R L +- -+ SPEAKERS R +- L A -+ B Amplifier or Receiver s Connections q Connect the screw-type input terminals at the rear of the speakers to the speaker output terminals of your amplifier with the speaker cables. q Connect the (+) terminals on both the amplifier and the speakers using one side of the cable. Connect the (-) terminals on both components using the other side of the cable. q Connect one speaker to the left (marked L) terminals of your amplifier, and another speaker to the right (marked R) terminals, making sure not to reverse the polarity (+, -). If one speaker is connected with reversed polarity, the sound will be unnatural and lack bass. Procedure: Loosen the terminal knob. Remove approx. 10 mm (3/8") insulation from the speaker cable and insert the bare wire end properly into the terminal hole. Tighten the knob. Test the security of the connection by tugging lightly on the cable at the terminal. Note Do not let the bare speaker wires touch each other as this could damage the speaker and/or the amplifier. 4 Amplifier or Receiver Amplifier or Receiver Both SPEAKERS A and B should be selected. Bi-Wiring Connections This speaker system is capable of bi-wiring connections. To connect the speakers to the output terminals of the amplifier, two pairs of cables for each of woofer and tweeter are used instead of standard connections. This type of connection decreases the modulation distortion caused by electric resistance of the cables and driving current of the speakers. Consequently, purer sound quality can be expected. To utilize bi-wiring connections, remove the short bars from the terminals first, and then connect the woofer and tweeter to the amplifier separately using two pairs of cables. Note For bi-wiring connections, use the same type of cable for both the woofer and tweeter, making sure to match the polarity.
