A Word About Digital Surround Technologies and THX

It is important to remember that THX technologies work in conjunction with whatever processing
technology it is paired. THX, on its own, is not a decoder or processor. It enhances and adapts the
surround sound processor it is paired with to more accurately reproduce movie soundtracks in the
home environment.

The new digital surround technologies, such as Dolby Digital

®

 (AC-3

®

) and DTS

®

, offer dramatic

improvements in channel separation and dynamic range over conventional multi-channel analog
matrix formats such as Dolby Surround

®

 and Dolby Pro Logic

®

. THX sound systems, with their

outstanding dynamic, spatial, and tonal performance, are ideally suited to convey the benefits of
digital multi-channel formats. THX technologies will continue to be essential for the accurate
reproduction of all multi-channel sources, both now, and in the future.

Connection

We recommend that you connect your new System 370 THX speaker components using high quality
wire of 16 gauge or larger. There are many respected manufacturers in the audio industry that
specialize in speaker wire and interconnect cables who make suitable products for your new system.
We recommend that you consult your local audio/video specialist for more specific information.

Warning: 

To prevent risk of electrical shock or damage to your equipment, always unplug all component

AC cords before proceeding with speaker and component connections! The last step in wiring your system is
plugging in the AC cords!

You can connect your System 370 THX speakers by using a variety of connectors, or by removing 1/2"
of insulation from each wire end, twisting the strands of wire together, placing the wire through one of
the post holes and screwing down the nut tightly. We recommend that you check your local electrical
codes to make sure you are not using an improper connector.

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 the wires in each pair is
marked by either a different color, printing, ridges, or a thread inter-
twined with the wire strands. By convention, the marked wire is
connected to the red (+) terminal.

Whether your are connecting a complete System 370 THX, or adding

one speaker or subwoofer to your present system, the wiring should usually look like the diagram in
Figure 2. When installing an Atlantic Technology subwoofer into your system, refer to the subwoofer’s
instruction manual for other wiring options. Before turning on the amplifier, be certain that no stray
wire strands are touching across the two terminals as this might damage your amplifier.
