User manual DUAL DC265

[. . . ] A common rule is to position the front speakers so that the distance between the listening position and the wall is 1. 5 times the distance between the two speakers, but the speakers can be further apart if you desire a wider sound stage. In a typical audio/ video multi-channel setup, the listening position is directly facing the video source (TV or Monitor) and the center channel is on a direct plane with the listener. If the listener is positioned 15 feet away from that video source, then the optimal distance between the left and right speakers would be 22. 5 feet apart (15'x1. 5). Listener Equidistant Example The speaker imaging decreases rapidly the further the listener is from the speakers, so an equidistant speaker arangment for multi-channel installation is desired for the best results. Try to equalize the speakers distance so the listener is basically in the middle of the sound stage. 3 DC265 / DC365 COVERAGE & SPEAKER PLACEMENT Sound Coverage and Speaker Placement When possible, try to reduce the distance of your speaker from the audio source to achieve the best audio results. [. . . ] The DC265 is designed to use the wall cavity as the enclosure. It is not necessary to install an enclosure unless required to do so by local electrical or fire regulations. The mounting tab brackets incorporated into the speakers can accommodate sheet rock or wall board thicknesses of 1/2" to 1-3/8". Spacers or longer screws can be used on thinner or thicker surfaces. Push Lock Speaker Terminals Built-in "easy turn" wall mounting tabs Adding insulation such as 3" to 4" insulation or damping material behind the speaker generally improves the sound quality. 5 DC265 / DC365 INSTALLATION Installation Tips Parallel or series wiring is not recommended for these speakers. The speakers should only be connected to receivers with 4-8 ohm amplifier loading. Avoid parallel or series wiring your Dual speakers with any other speaker type or brand. Always connect speaker wires using the correct 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 color type or colors of the wires/wire itself (copper or silver). Important: In order to maintain correct polarity, always connect speaker wire using the positive (+) terminal on the receiver to the positive (+) wire, and the negative (-) terminal on the receiver to the negative (-) wire. 6 DC265 / DC365 INSTALLATION Installation Guide When ceiling mounting your speakers, attempt to make the locations as symmetrical as possible. When wall mounting, carefully measure the distance from the floor to the speaker center so both speakers are the same distance from the floor. You may use the template that is included with your Dual speakers to determine the correct cut-out dimensions. Cut the hole or opening using a sheet rock saw, keyhole saw or other suitable tool. Place the speaker in the opening to verify a correct flush fit. Remove the speaker grille at this point of the installation to gain access to the screws which turn the mounting tabs that will secure the speaker to the mounting surface. The screw heads that lock the tabs can be identified by turning the speaker over and pushing on the tab. The corresponding screw head will protrude identifying which screws you will need to turn once the speaker is connected, and in the proper position within the wall or ceiling. Run speaker wires from the amplifier to the speakers. Allow an extra 2' of wire at the speaker cutout location to make installation easier. Strip and twist about 1/2" of insulation off the speaker wires. The speaker wire runs should be hidden as well as possible within the wall or ceiling and should not come in contact the speaker basket, be wrapped around the crossover network or hang loosely near a stud as vibration may cause poor sound quality. Insert the speaker into the opening cut in the wall or ceiling, slide the whole speaker into the wall cavity and center the speaker in the opening.
