Remember to keep the original boxes and packing material, in the unlikely event the speakers need servicing, or if you move. Attaching the Grilles The included metal grilles are held to the front of the enclosures with powerful neodymium magnets. There are depressions on the back of the grille that the magnets fit into. Once the speakers are in their final position. Position the grille over the magnets on the baffle. (See Figure 1) Move them together slowly and when you get close enough, the magnets will draw the grille in and hold it tight. Be careful not to get your fingers caught between the grille and the cabinet. NOTE: You will notice a threaded insert onthe back of the LR satellites and SR surrounds. This is for bolting the satellites to speaker stands that utilize a slotted L-bracket. Use a ¼" x 20 bolt to secure the speaker to the stand. For Future Reference Record the serial number and date of purchase for each speaker here. The serial number is found on the speaker terminal panel on the back of the enclosure.

Individual Component Descriptions Instruction Manual 3 Individual Component Descriptions Model 920,1200 and 2200 LR Front Channel Speakers The Model 2200 LR Front Channel Speakers (Figure 1) are high-performance 2-way systems intended for use with a quality subwoofer, such as the Atlantic Technology Model 920 SB, 212 SB or 422 SB box-type subwoofer. Each speaker contains two GLH (Graphite Loaded Homopolymer) 4 ½" (115mm) woofers and an advanced 1" (25mm) ferrofluid-cooled, damped soft dome tweeter with a powerful neodymium magnet structure. The drivers are configured in an M-T-M array (midrange-tweeter-midrange alignment) This vertical arrangement of drivers provides wide left to right coverage of sound while limiting the floor and ceiling reflections that may color the sound. These components are mounted in an acoustically inert MDF enclosure. The LR speakers are magnetically shielded so they may be placed close to a TV set without concern. Model 1200 LR speakers are very similar to the 2200 LR speakers, except they employ one 4 ½" GLH woofer instead of two. The Model 920 LR speakers are a scaled down verion of the 1200 LR speakers and employ a single 4" driver but the same tweeter as both the 1200 and 2200 LR's. Figure 1 2200 LR 1200 LR 920 LR Figure 2 Model 1200 C and 2200 C Center Channel Speaker For accurate reproduction of a multi-channel soundtrack, the three frontchannel speakers must have the same sonic signature. Therefore, the 1200 C and 2200 C Center Channel speaker utilize the same driver elements as the respective matching LR speakers (see Figure 2). These speakers are designed to be placed horizontally. They are also magnetically shielded and can be placed directly adjacent to your TV set with no adverse effects on the television's picture. Both can be tilted on their dedicated base to provide optimum sonic coverage of the listening area. 2200 C 1200 C Acoustic Controls System 1200 C and 2200 C includes unique acoustic controls to help maximize its performance in your room. These controls are explained in greater detail on page 8. Figure 3 Model 2200 SR Surround Speakers The Model 2200 SR Dipole/Bipole Surround Speakers (Figure 3) are intended for use in multi-channel audio/video sound systems as dedicated side or back surround channel speakers. The 2200 SR enclosure has two 4 ½" (115mm) GLH woofers and two of the same high performance soft dome tweeters found in the 2200 front speakers. The surround speakers can be switched between Dipole and Bipole operation. These settings are explained on page 8,"Dipole/Bipole Operation of the SR Speakers." Because of their small size, both the model 920 LR and 1200 LR make an excellent surround speaker. When using either LR as a surround speaker, the best results will be obtained if the speakers do not aim directly at the listening area. Mount the LR's on the side walls, above and slightly behind the listening position (See page 5). 2200 SR NOTE: Although the speakers in the Atlantic Technology Systems 920, 1200 and 2200 are acoustically and cosmetically matched to each other for ideal results, they may also be used with other Atlantic Technology components and a wide variety of speakers from other manufacturers with excellent results. 4 Placement System 920, 1200 and 2200 High Performance Loudspeakers Placement Speaker/room interactions have a huge impact on the sound of the system. Moving the speakers just a little can make a dramatic difference in what you hear. Remember that the best acoustic placement of the speakers will vary from room to room. Use the following placement guidelines (see opposite page) as a starting point. But also feel free to experiment. In fact, it may be beneficial to hook up the front LR and surround speakers with some extra wire and to simply drape the wire across the floor before installing the speakers permanently. This will allow you the opportunity to move the speakers around easily so you can find the best sonic and visual locations. Surround Effects and Speaker Locations The 2200 SR's shape allows great flexibility in placement. Due to the switchable Dipole/Bipole design, it's possible to place the speakers almost anywhere within the rear third of the room and get good results. However, the best location for surround speakers is straight out to the sides, or slightly behind the primary listening area, approximately 1-2 feet (.3-.6m) above seated ear level, but no closer than 2 feet (.6m) from the ceiling. As noted above, the surround speakers (as opposed to the back speaker(s) in a 6.1 or 7.1 channel system, see below) are primarily intended to re-create the ambient sounds taking place in the movie scene. Therefore, throughout most of a movie or TV program you may not be consciously aware of output from these speakers. In other words, don't worry if you aren't hearing the surround speakers. Please try to avoid the trap of turning the surrounds up and up so that you hear them most of the time. The result will be a much less believable surround experience. There are dedicated LEFT and RIGHT model 2200 SR speakers. This is clearly marked on the back of each speaker. Be sure that the Left side surround speaker is placed directly to the left side of the prime listening area (facing the screen) and the Right speaker is directly to the right side. Home Theater Remember that the primary goal of a good home theater is not to make you believe that you are in a movie theater. It's to make you believe you're in the movie. For a home theater system, place the LR speakers on either side of the television. The three front channel speakers (LR and C) are magnetically shielded so they will not interfere with your television picture. The left and right front speakers should be far enough apart (6 to 10 feet, 2-3 meters, is usually best) that you get a good stereo "image" when they are playing alone, but not so far apart that the sound seems to be disembodied from the TV, distracting you from the picture. When using a center channel speaker, a wider separation of the left and right front speakers is usually possible. You may chose to "toe" the LR speakers in, aiming them approximately at the prime listening position. This can be particularly useful if the front LR speakers are fairly far apart. IMPORTANT NOTE Try to keep the LR and C tweeters at approximately the same height and aimed at ear level when seated. This is because we've designed the alignment of the drivers on the front panel to limit the vertical spread of the mid and high frequencies, thereby reducing the floor and ceiling reflections that adversely affect sound quality. If the speakers are too high or too low however, you will miss a significant portion of the upper middle and high range elements of the sound. This alignment of the drivers provides enhanced horizontal spread of the sound making for a much better sound experience for a group of listeners and reducing the need to sit in a precise "sweet spot." 6.1 and 7.1 Channel Systems For best performance in a 7.1 channel system, we recommend using another pair of 920, 1200 or 2200 LR's on the back wall, and 2200 SR's on the side walls. If you are setting up a system that uses back surround speaker(s) as well as side surrounds (Dolby Digital EX, DTS ES, etc.) you can choose to use either SR model speakers in Dipole or Bipole mode or another pair of front LR speakers in the back of the room. If the 2200 SR's are used as back surrounds in a 6.1 or 7.1 channel system, they should be installed with the Right speaker placed over the listener's left shoulder and the Left speaker placed over the listener's right shoulder; these back surrounds should be placed approximately 150 degrees from the screen on the back wall. About one-third of the way out from the corners in most rooms is a good starting point. If you are using a THX Ultra 2 certified controller/receiver, you should place the back surround speakers approximately 1 to 2 feet (.3-.6m) apart in the center of the back wall. The special circuitry in the processor will help to create a believable and effective surround field using this placement. Please read the electronics manual to learn more about this placement option. Speaker Placement Instruction Manual 5 Speaker Placement 6 Connecting Your System System 920, 1200 and 2200 High Performance Loudspeakers Stereo Systems If you are setting up a stereo system using a pair of 920, 1200 or 2200 LR's with subwoofer(s), begin with these general guidelines: Connecting Your System We recommend that you connect your system using high quality dual conductor stranded wire of 16 gauge or heavier, for lengths up to 25 feet (8m) . Remember, the lower the gauge number, the heavier the wire. Use heavier gauge wire for longer runs. Please contact your audio/video dealer or installer for specific cable recommendations and further information regarding special circumstances. The terminals themselves are designed to allow the use of very heavy speaker wire or connectors. Be sure to tighten them securely, but don't over-tighten them.
