User manual DUAL LU53P

[. . . ] Room acoustics can produce large apparent differences in the sound when small changes in the placement are employed. For example, although the speaker may be located at any height above the floor, directing the tweeter toward ear level (32" ­ 36") or angling the entire speaker toward the listening position often provides the most realistic imaging experience. The amount of bass perceived increases as you move a speaker closer to solid intersecting room surfaces (walls, ceiling, floor). Speaker Placement Wall and Ceiling Placement Experiment for Better Sound (6'10") Recommended minimum distance between speakers 3 ® LU43P-LU53P INSTALLATION Placement & Mounting Speakers Outdoor Placement The DUAL LU43 and LU53 have been tested for environmental usage and are weather resistant, but not waterproof. The speakers should be allowed to ventilate and dry after water exposure. [. . . ] 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. 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. 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. 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. This can be confirmed visually. Distortion/Knocking Troubleshooting If you hear obvious distortion from the speakers, immediately lower the volume level of your receiver. Those sounds often indicate that either the receiver or the speaker is being overdriven, and damage can result in playing your source material (music-CDs-DVD-MP3) at high volume levels for prolonged periods of time. You should also avoid turning the bass or treble controls fully up and using your "Loudness button" when the volume level is at or above normal listening levels.
