manual abstract
Your new speaker system is precision crafted to give you years of enjoyable, trouble free service. This manual covers the Atlantic Technology T70 series of speakers for home theater. The T70 PBM Subwoofer is covered in detail in a separate manual. Every T70 component has been optimized for use with all surround sound formats including Dolby Surround®, Dolby Pro-Logic®, Dolby Digital 5.1®, Surround EX 6.1®, and DTS®. T70 LR Front Channel Speaker The T70 LR Front Channel Speakers are two-way systems intended for use only with a quality subwoofer. Each speaker contains a 4" TCMG (Titanium Coated Molded Graphite) woofer, and a 1" Ferrofluid® cooled, Soft Dome tweeter with a powerful neodymium magnet, in an acoustically inert MDF cabinet. The T70 LR speakers are magnetically shielded so they may be placed next to a TV set without concern. T70 C Center Channel Speaker The T70 C uses dual 4" TCMG woofers and the same 1" tweeter as the T70 LR speaker. The T70 C is designed for use only as a dedicated center channel speaker. The T70 C center speaker should be placed in a horizontal position, directly above or below the TV screen. It too is magnetically shielded and will have no adverse effects on the TV. T70 SR Surround Speaker The T70 SR TriVector™ Surround Speaker is intended for use in multi-channel audio/video sound systems only as a dedicated surround speaker. 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). Use 16 gauge or larger for runs up to 30 feet and 14 gauge for runs up to 50 feet. Contact your Atlantic Technology dealer for specific cable recommendations and further information for special circumstances. Warning: To prevent risk of electrical shock or damage to your equipment, always switch off the amplifier or receiver when making connections to the speaker. aaaaaaaaaaaaaaaaaaaaaaaaa0 2 aaaaaaaaaaaaaaaaaaaaaaaaa0 Atlantic Technology ® You can connect your T70 speakers by using a variety of audio connectors such as pin connectors, spade lugs, etc., or you can: 1. Remove 1/2" of insulation from each wire end. 2. Twist the stranded wire together, keeping the two conductors separate. 3. Place the appropriate conductor through the appropriate postholes in the connectors. These holes are revealed when you loosen the connector capscrew. 4. Screw down the capscrew tightly, but be careful not to over tighten. 5. Check the tightness of the capscrews 24 hours after hookup and occasionally thereafter, as they can loosen over time. We recommend that you check your local electrical codes to make sure that you are not using an improper connector. Figure 1: It’s important to observe polarity while making speaker connections: red (+) Gold plated terminals on the amplifier to red (+) on the speaker, black (–) on the amplifier 5-way binding to black (–) on the speaker. Look carefully at the wires you are using and note posts. Accepts that one of conductors of each pair will be identified by color, printing on the up to 10 gauge outer jacket, ridges on the outer jacket, or a thread intertwined with the wire bare wire strands. By convention, the marked wire is connected to the red (+) terminal. When you’re done hooking up your T70 system the wiring should look like the diagram in Figure 2. 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 music. If the sound seems hollow, unusually spread out, or has weak bass, recheck your connections for proper polarity and reverse any out of phase connections, if necessary. Usually one speaker wired out of phase is the culprit. Placement and Operation Speaker/room interactions have a huge impact on the sound of the system. Moving the speakers just a little bit can make a dramatic difference in what you hear. The ultra-compact design of T70 provides you with maximum placement flexibility, while creating a large, seamless, acoustically accurate soundfield for your home theater or music system. The best placement of the speakers will vary from room to room. Use the following placement guidelines and Figure 3 as a starting point. But also feel free to experiment. In fact, it may be beneficial to hook up the 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 a...
