User manual DUAL LU63PB

[. . . ] The LU63 speakers have two standard 1/4-20 brass inserts incorporated into the rear of the enclosure for aftermarket mounting systems. Experiment for Better Sound We recommend that you take the time to experiment with different speaker placements. Sound quality and imaging are widely dependent on the location of your speakers as well as room acoustics. Angling each speaker toward the listening position often provides the most realistic imaging experience. [. . . ] Once mounted, the bracket allows the speaker to be angled to its ideal position. The included thumb screws will hold the selected speaker position when properly tightened. Before attempting the installation, carefully evaluate the mounting surface to ensure that its composition and construction are capable of safely supporting the weight of the speaker. If you are unsure about the type of mounting hardware to use, consult a professional contractor or a knowledgeable hardware store. Note: Anchors and screws needed to mount brackets are not included and must be purchased separately. 4 ® LU63PB-LU63PW CONNECTION Connecting Speakers Connecting Your Speakers Speaker Wire -We recommend the use of two conductor 18-gauge speaker wire to connect the speakers to your receiver. 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. Polarity - Speaker wire polarity is indicated by either a color stripe on the insulation, ridges molded into one side of the insulation, the color of the insulation case around the wire, or by the color of the wire itself (copper or silver). LU63PB Connect speaker wire using the positive (+) terminal on the receiver to the positive (+) speaker terminal, and the negative (-) terminal on the receiver to the negative (-) speaker terminal. All speakers in a system must be connected with the same relative polarity. Connection - It is recommended that the speaker wire insulation be stripped back approximately 3/8", allowing the wire conductor to make a proper connection. The gold terminals have red (positive) and black (negative) polarity indicators. Loosen the gold terminals by turning counterclockwise. Banana style connectors may also be used. 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. Note: Do not allow the positive and negative speaker wire from the receiver to make contact at any time, as this will cause a short. 5 ® LU63PB-LU63PW TROUBLESHOOTING Troubleshooting & Specifications Distortion/Knocking If you hear obvious distortion from the speakers, immediately lower the volume level of your receiver. Distortion 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 up and using your "Loudness button" when the volume level is at or above normal listening levels. Note: The Loudness button on most receivers is designed to add depth when your system is being used for background music or at very low volume. Distorted or unnatural sound can indicate poor connections, defective electronics, damaged source material or speaker failure. If only one speaker has poor sound quality, check the speaker wire and audio connections. If that doesn't fix the problem, try putting each speaker in place of one another (swapping). If the sound remains poor on the suspect speaker after swapping location and the distortion moves with the speaker to the new location, the speaker may be the problem. [. . . ] Before you call for service, check the troubleshooting guide in your owner's manual. A slight adjustment of any custom controls or connections discussed in your instruction booklet may save you a service call. If you require service during the warranty period, you must carefully pack the product (preferably in the original package) and ship it by prepaid transportation with a copy of the original receipt from the retailer to an authorized service center.
