SYSTEM T90
High Performance Compact Home Theater Loudspeaker System
Thank you for choosing Atlantic Technology home theater products. Your new speaker system is precision crafted to give you years of enjoyable, trouble free service. This manual covers the Atlantic Technology T90 series of speakers for home theater. The T90 PBM Subwoofer is covered in detail in a separate manual. Every T90 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 all DTS® surround formats.
T90 LR Front Channel Speaker
The T90 LR Front Channel Speakers are two-way systems intended for use only with a quality subwoofer. Each speaker contains a 5.25" TCMG (Titanium Coated Molded Graphite) woofer, and a 1" Ferrofluid® cooled, Fabric Dome tweeter with a powerful neodymium magnet, in an acoustically inert MDF cabinet. The T90 LR speakers are magnetically shielded so they may be placed next to a TV set without concern.
T90 C Center Channel Speaker
The T90 C uses dual 5.25" TCMG woofers and the same 1" tweeter as the T90 LR speaker. The T90 C is designed for use only as a dedicated center channel speaker.
The T90 C center speaker is designed to be used 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.
T90 SR Surround Speaker
The T90 SR TriVector™ Surround Speaker is intended to be used in multi-channel audio/video sound systems only as a dedicated surround speaker. Each enclosure has a 5.25" TCMG woofer on its 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 high frequency ambience with limited midrange localization. The T90 SR’s unique TriVector design makes it well suited for all analog and digital surround applications.
IMPORTANT NOTE: The unique shape of the T90 SR lends itself to more than one mounting method.
By aiming the front mounted driver directly at the prime listening position, you can create a more localizable surround field. Aiming them away produces a more diffuse surround field. Simply choose the appropriate threaded insert to attach the keyhole adapter.
Connecting Your System
We recommend that you connect your T90 system with high quality dual conductor stranded wire of 18 gauge or larger, for runs up to 15 feet. (Note: The lower the gauge number, 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 speakers.
You can connect your T90 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. 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.
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 conductors of each pair will 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.
When you’re done hooking up your T90 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.
After all the connections are made check the polarity of your front speakers by listening to stereo 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 compact design of T90 provides maximum placement flexibility, while creating a large, seamless, acoustically accurate soundfield for your 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 around easily so you can find the best sonic and visual locations.
Home Theater Placement
Our philosophy is simple. We believe the primary goal of a surround sound system isn’t to make you think you’re in a movie theater. It’s to make you believe you’re in the movie or at the concert. So for
