User manual ATLANTIC TECHNOLOGY 370 IN-SR INSTRUCTION MANUAL

[. . . ] This unique speaker has been optimized for use with any multi-channel sound format including Dolby Surround®, Dolby Pro-Logic®, Dolby Digital 5. 1® and DTS®. The Model 370 IN-SR Surround Speaker is intended for use in audio/video sound systems with dedicated surround channel speakers. Each speaker has two 5-1/4" CCMG (Coated Composite Molded Graphite) woofers, as well as two 3/4" fabric dome tweeters which are angled and phased to produce ambience without localization. Its wide bandwidth and unique construction makes it especially suitable for Dolby Digital and DTS applications. [. . . ] These holes are revealed when you loosen the connector thumbscrew. We recommend that you check your local electrical codes to make sure that you are not using an improper connector. 2 Atlantic Technology® It is 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 conductors of each pair is marked by a different color, printing, ridges, or a thread intertwined with the wire strands. By convention, the marked wire is connected to the red (+) terminal. Warning: Before turning on the amplifier, be certain that no stray wire strands are touching across the two terminals as this might damage your amplifier. Home Theater Please note 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 are in the scene taking place on the screen. Note: Most discrete digital home theater systems allow you to select between "Small" and "Large" surround speakers. Since the 370 IN-SR is a THX certified speaker it has been designed only to work with a subwoofer used to reproduce frequencies below 80 Hz. Therefore, please set the processor for "Small" surround speakers. Surround Effects The 370 IN-SR's size, shape, and unique ability to mount on, or recessed within, a standard wall significantly increases its placement flexibility and dramatically reduces its visual room intrusion. The result is greater flexibility in placement than the vast majority of conventional surround loudspeakers. Installation instructions for the 370 IN-SR are detailed on the enclosed cardboard mounting template. Due to the 370 IN-SR's dipole spatial characteristics, it is possible to place the speakers in a number of locations, but usually the best location is straight out to the sides of, or slightly behind the primary listening area, approximately 1-2 feet above ear level. Note: Since the surround speakers are intended to re-create the ambient sounds taking place in the movie scene you may not be directly aware of their presence for much of the movie. This is because the signal they receive is almost overwhelmingly subtle sounds that are intended to make you believe you're "where the action is. " Mounting Note: In-wall installation instructions for the 370 IN-SR are detailed on the enclosed cardboard mounting template. The orientation of the 370 IN-SR's is important to the proper generation of an involving and diffuse surround effect. Mount each speaker on the wall or within a wall so that the "direct" soundfield is aimed toward the front of the room, and the "ambient" soundfield is directed toward the rear. To insure this orientation, make sure that the RIGHT speaker is on the right side wall of the room, and the LEFT speaker is on the left side wall of the room. The speakers are marked RIGHT and LEFT on the back. 3 Models 4. 5 LR, 4. 5 C, and 4. 5 SR To mount your speakers on a wall, we have installed metal key-hole brackets on the back of the 370 IN-SR. Be sure to use a strong screw whose head and shaft will fit within the keyhole opening and slot. Also be sure to drive the screw well into a stud or use a mounting device (such as a molly-bolt) that is capable of holding the weight of the speaker. [. . . ] In any case, save all packing materials until you are certain that the systems have suffered no damage in shipment. If you find such damage, either visible or internal, contact your dealer immediately for the proper return procedure. 370 IN-SR Specifications Model Type Drivers Frequency Response (± 3dB) Nominal Impedance Crossover Frequency Sensitivity Recommended Amplifier Power Magnetic Shielding Weight 370 IN-SR Sealed enclosure, frequency-enhanced on-wall/in-wall THX certified dipole surround speaker 2 ­ 5-1/4" CCMG woofer/midrange, 2 ­ 3/4" silk dome fluid cooled tweeters 80Hz ­ 20kHz 8 3. 5kHz 87dB 100 ­ 200 WRMS No 12lbs. , 5. 45kg Specifications are those in effect at the time of printing.
