User manual DUAL LU43P

[. . . ] Your speakers can be placed in many convenient locations in your home or patio area - as stereo pairs on either side of your receiver - as surround speakers in home theater surround sound systems - in your computer room to enhance the multimedia experience - or as remote speakers. For wall and ceiling applications, DUAL mounting brackets are included. In addition, the LU43 has a rear inset keyhole for surface hanging, and the larger LU53 has two 1/4-20 brass inserts incorporated into the rear of the enclosure if aftermarket mounting systems will be used. You should experiment with various placements. [. . . ] The hardened steel brackets are suitable only for attaching the speaker to walls or ceilings constructed of solid wood, brickwork, concrete, hollow buildings block or wood studs. Do not mount the bracket to non-reinforced plaster sheetrock (gypsum board). Once the bracket is secure, reattach the speaker using the thumb screws included. 4 ® LU43P-LU53P CONNECTION Connecting Speakers Connecting Your Speakers Speaker Wire -Typical speaker wire has a pair of separate speaker wires with insulating jackets that are molded together. Dual recommends the use of two conductor 18gauge speaker wire to connect your speakers to your receiver. Measure enough wire to reach from your receiver to each speaker plus additional length to allow moving the speakers or receiver without having to disconnect the wires. When connecting the speakers in a stereo configuration, the wire length should be similar. One length should not be dramatically longer or shorter then the other. Maintaining similar wire lengths will provide superior sound quality. LU53P Polarity - Speaker wires are marked for polarity consistency so that you can determine the positive and negative identity of the individual wires within the molded pair insulation. Polarity is shown by either a color stripe on the insulation, by ridges molded into one side of the insulation, the color of the insulation case around the wire, or by the colortype or colors of the wires/wire itself (copper or silver). Important - Always connect speaker wire using the positive (+) terminal on the receiver to the positive (+) terminal, and the negative (-) terminal on the receiver to the negative (-) terminal. All speakers in a system must be connected with the same respective polarity. The speaker inputs are located on the rear-mounted terminal cup on the back of the speaker. Terminal Type - The LU43 utilizes a push-pin design. Gently depress the colored lever and insert the stiped end of the wire directly into the opening located in the center of the input housing. - The LU53 uses a screw type input post. To loosen, turn the gold terminal counter clockwise, insert the wire end and re-tighten. The gold terminal have Red (POS) and Black (NEG) polarity indicators. LU43P 5 ® LU43P-LU53P CONNECTION & TROUBLESHOOTING Connecting Speakers Your Speakers The speaker wire must be securely connected and tightened properly to the speaker inputs. Do not allow the positive and negative speaker wire from the receiver to make contact, as this will cause a short. Banana style connectors may also be used on the LU53. The connection is made by connecting the speaker wire to the banana plugs, and then inserting the banana plug into the top portion of the binding posts. It is recommended that the wire insulation be stripped back approximately 3/8", allowing the wire conductor to make a proper connection. Make sure that the wire insulation is stripped back far enough so that the bare speaker wire will make a proper connection to the metal clip inside the terminal and be securely held in place.
