Your new speaker components are precision-crafted to give you years of enjoyable, troublefree service. This manual covers the Atlantic Technology System 920, 1200 and 2200 speaker components. It will show you how to incorporate these components into your present setup, as well as how to assemble a complete system from them. [. . . ] 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. 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. Toe the speakers in or point them straight ahead. Pull them away from the wall or push them closer. Don't be timid. You'll find that moving your speakers, even a few inches, can dramatically change and possibly improve their sound. We recommend that you check your local electrical codes to make sure that you are not using improper connectors. It's important to observe polarity while making speaker connections: red (+) terminals on the amplifier to red (+) on the speaker, black (­) on the amplifier to black (­) on the speaker. Look carefully at the wires you are using and note that one of the conductors of each pair will typically be identified by color, printing on the outer jacket, ridges on the outer jacket, or a thread intertwined with the wire strands. By convention, the marked wire is connected to the red (+) terminal. Whether you are connecting a complete system, or adding a single speaker component to your present system, the wiring should look like the system wiring diagrams on the opposite page WARNING: Before turning on the amplifier, be certain that no stray wire strands are touching across any terminals as this might damage your amplifier. Finally, check the polarity of your front speakers by listening to some stereo music with good bass content. If the sound seems "hollow", unusually spread out, or seem to have weak bass, recheck your connections for proper polarity and correct any out of phase connections, if necessary. System Wiring Instruction Manual 7 System Wiring Be sure to connect red (+) on the speaker to red (+) on the amplifier and black (­) on the speaker to black (­) on the amplifier.

[. . . ] This connection is recommended not only for better sound but for safety (especially if you have little ones running around) The recommended stand height is approximately 30". See Figure 5. On the Wall To mount your speakers on a wall, we have supplied metal key- hole brackets attached to the back of the cabinet. These speakers are heavy and care must be used when hanging them. Be sure to use a strong screw to drive into the wall, one whose head and shaft will fit within properly the keyhole opening and slot. [. . . ]
