User manual ATLANTIC TECHNOLOGY SYSTEM T70 INSTRUCTION MANUAL

[. . . ] Each enclosure has a 4" CCMG (Coated Composite Molded Graphite) woofer on the front and two wide dispersion 3/4" Modified Dome tweeters, one on each side. The dual tweeters and single woofer are electronically phased to produce diffuse ambience with limited localization. The T70 SR's unique TriVector design makes it well suited for all analog and digital surround applications. Connecting Your System We recommend that you connect your T70 system with high quality dual conductor stranded wire of 18 gauge or larger, for runs up to 15 feet. (Remember, the lower the gauge, the larger the wire). [. . . ] It's to make you believe you are in the scene taking place on the screen. For a home theater system, optimum placement of your T70 LR speakers is 2 to 3 feet to either side of the television and 1 to 2 feet out from the wall, at ear height when seated. The left and right front speakers should be far enough apart that you get a good stereo image, but not so far apart that the sound seems to come directly from the speakers, distracting you from the picture. You may choose to "toe" the LR 3 Models T70 LR, T70 C, and T70 SR Figure 2: Typical wiring diagram for speakers in a home theater. To optional second subwoofer speakers in, aiming them at the prime listening position. This can be particularly useful if the LR speakers are fairly far apart. The T70 C should be placed directly above or below your television. It's important that the speaker is centered on the screen, not off to the side. Place the separate speaker base so that the foot "cutouts" are closest to the front. Sit the speaker's feet in the cutouts and tilt the speaker so that it points at the listening position. Try to keep the T70 C no more than 2 feet higher or lower than the LRs. Important Note: Most surround sound decoders and receivers offer a choice of "Normal" or "Wide-band" or "Large" and "Small" modes for the some or all of the speakers in their setup menus. All T70 speakers must be used in the Normal or Small mode, if this choice is available. Surround Effects The T70 SR's size allows great placement flexibility and its unique TriVector spatial characteristics make it possible to place them almost anywhere within the rear third of the room. The best location however, is straight out to the sides of the prime listening position (+/- 15 degrees), approximately 18 to 24 inches above ear level. Do not block the sound emanating from the side-mounted tweeters. Important Note: The surround speakers are intended to re-create the ambient sounds taking place in the movie scene. Throughout part or most of a movie you may not be directly aware of the surround speakers' presence. Try to avoid the trap of turning the surrounds up so loud that you hear them all the time. The result will be a much less believable surround sound experience. 4 Atlantic Technology® Figure 3: Typical arrangement for speakers in a home theater. For best results, place the surround speakers within the shaded area. Surround speaker should be no closer than 2' from the ceiling Surround speaker Ear level Center channel should be within 2' of front speaker tweeter height Surround speaker Null point of surround speaker in line with listening position Music If you wish to seriously listen to music these general placement guidelines should help: q The distance between your front LR speakers should be approximately one-half their distance from your favorite listening position. If you point the front of the speakers directly towards the prime listening position, you will achieve the most precise imaging. You will also receive the maximum amount of direct radiated high frequency energy. If you have a "bright" or "hard" sounding room environment, aiming the speakers straight out into the room (or just aiming them partially towards you) may make for a more natural and pleasing sonic balance. [. . . ] The harsh amplifier "clipping" that occurs in this situation will inevitably cause damage to the speaker system. This type of damage is easily identifiable through examination of the speaker's voice coil and is not covered by warranty or service agreement. Care and Feeding of Your Speakers Clean your speaker cabinets using a soft cloth moistened with a mild, non-abrasive glass cleaner being careful not to wet the edges of the cabinet. Also, be careful not to get any cleaning fluids on the driver cones or domes. It's best to dampen the cloth with the cleaner and then wipe the speakers. [. . . ]
