That way, all the bass from 60Hz and above will be sent to the Front Stage Loudspeaker, which will result in a full-bodied, credibly full-range sound to be reproduced, while at the same time, preventing the very low bass signals (below 60Hz) from overdriving the receiver's amplifier section at high output levels. HFENERGY •-©REVERBERANT DAMPED / ROOM \ —©AVERAGE System Setup 7 Ц Instruction Manual Speaker Placement — Optional Surround and Subwoofer --. Optional Dipole/Bipole Speakers should be placed directly to the sides of the seating area and approximately 1-2 feet (.3-.6 meter) above the listener's ear level. FS-4000 or FS-5000 Optional Subwoofer Left Surround Left 2200 SR Right 2200 SR Optional Direct Radiator Speakers (if used) should be placed slightly behind the listening position, and same height as dipole/bipoles. 920 or 1200 LR's are appropriate. Left Surround Back a Right Surround Right Surround Back Optional Surround Back Speakers should be placed approximately 1-2 feet (.3-.6 meter) above the listener's ear level and 30 off the center axis. Direct radiators (920, 1200 or 2200 LRs) may be used here. ^ 8 System Setup Using Optional Surround Speakers If you are setting up a full home theater system, any of our surround speakers, boxed or in-wall, will work very well with the Front Stage Loudspeakers. All Atlantic Technology speakers are “voiced” to the same standards of tonal neutrality and sonic accuracy. Our model 2200SR Bipole/Dipole surround speakers, for example, would be an excellent match for an FS-based home theater system. Begin with the side speakers set to “Dipole,” then experiment with the Bipole/Dipole switch to obtain the most pleasing and realistic effect in your listening room. See your Atlantic dealer or visit our website (for more information. 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 (see previous page). The surround speakers 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. Setting Levels When setting up a complete home theater we strongly recommend that you use a Sound Pressure Level (SPL) meter. As of this writing Radio Shack® has one that’s affordably priced (approximately $40-$60) that can be used effectively. To use this meter, turn on your system, put the processor/receiver in Test Mode and set its main volume control somewhere between -20 dB and 0dB (or a reasonably loud level in your listening room). Sit in the prime listening position, set the SPL meter to the 70dB scale, slow response, and C weighting. Hold the meter with the microphone pointed up towards the ceiling and in front of you. Cycle the test tone from speaker to speaker, setting each to the same level (usually75dB) using the individual level settings available in the processor/receiver (please see the instructions for your processor/receiver if you are unsure of how to access the test signal or level controls). IMPORTANT NOTE: The power recommendation for these speaker systems assumes that you will not operate your amplifier/receiver in a way that produces distortion. Even rugged speakers like these can be damaged by an amplifier driven into audible distortion. The harsh amplifier distortion ("clipping") that occurs in this situation will eventually cause damage to the speaker system. This type of damage may be cumulative and can build up over time, as the amplifier is driven into overload again and again. Such damage is easily identifiable through examination of the damaged speaker's voice coil and is not covered by the warranty. These systems will play very loudly when provided with enough undistorted power to do so. If necessary, consult your dealer or Atlantic Technology for additional information. Front Stage Loudspeakers 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. WARNING: To prevent risk of electrical shock or damage to your equipment, always switch o...
