New Construction and Retrofit Installations

Note:

A new construction rough-in kit and back box kit are optional

available from Atlantic Technology Please refer to the instructions included

m those kits for their use. If the rough in kit has been used please go directly

to Step 2 below

Mounting Hole Specifications:

IWTS-6 CMS: Diameter = 7-7/8 in, 205mm. Depth = 3-7/8 m, 98mm

IWTS-8 CMS Diameter = 9-1/2 in, 247mm. Depth = 4-1/4

n. 108mm

Cut an appropriately sued opening in the ceiling material. Be sure that

the ceiling material can support the weight of the speaker. Also be sure

that the sides of the opening are at least 1-1/2 inches away from any

beams or studs within the cavity. II it is not. the rotating clamps will be

restricted in their movement and may not damp properly.

Be sure that all foreign material in the ceiling is kept out of the speaker

assembly, particularly the back of the woofer cone. (There is a doth

shield on the rear of the woofer, but please use care anyway.) If the

ceiling is void of insulation it will be beneficial to the performance of

the speaker to install an Atlantic Technology foam Sound Damping Kit

behind and around the assembly.

IMPORTANT: Depending

md mode

reo or

sur¬

round) you

intend to use. certain settings must be made before installing

your speaker! s).

Jumper Settings Find the jumper pins on the crossover board of your

speaker. They are the same for both the 6 ( MS and 8 ( MS. For Stereo

operation, install the jumper blocks as shown in Figure 2A. For Mono/

TriVector operation, install the jumper blocks as shown in Figure 2B.

Operation Settings To set the 6 CMS for Normal (mom) or stereo)

operation, attach the wiring connector to the pins marked NOR on

the crossover hoard as shown in Fig. 'A. For Trivector surround

operation, attach the connector to the pins marked SLR (Fig. 3B).

To set the 8 CMS for Normal (mono or stereo) operation, set the

upper selector switch located on the tweeter assembly to NOR. For

TriVector surround operation, set the selector to SIR (see Fig. 4A)

Use the high frequency level adjustment, also located on the tweeter

assembly, to increase (♦) or decrease (-) the level of high frequency'

sound produced by the tweeters. The settings on the 8 CMS can easily

be changed after the speaker is installed (see Fig. 4B).

Figure 2B

Attach the previously installed audio feed wires to the appropriate

speaker terminals. For Mono or TriVector operation either set of input

terminals may be used. For Stereo operation one set ol leads is attached

to each set of input terminals. Simply remove 1/2 inch of insulation from

the end of each input wire. Push down on the terminal connector and a

large opening will appear in the shaft of the connector that is capable of

holding up to 10 gauge wire. Insert the bare wire into the opening and

release the terminal. Be sure to observe correct polarity, connecting the

positive (+) leads to the red terminals and the negative (-) leads to the

black terminals. Also be sure that no stray strands of wire touch across

any terminals. See Figure 5.

Check to ensure that the rotating clamps are "parked" and not sticking

out over the edge of the assembly.

Push the speaker assembly straight up into the opening with the tweeters

oriented as noted previously.

Tighten the mounting screws one at a time. As you tighten, the rotating

damps on the back of the assembly will turn and lower, until they contact

the hack of the ceiling and damp the ceiling between themselves and

the trim ring. Sec Figure 6.

Mono/TriVector

Snug all four mounting screw s in this manner to make a firm seal with

the ceiling. Be careful not to overtighten them.

Start the system and make sure the speakers are operat-

ing properly. If you have installed the 8 CMS adjust the high

frequency switch (on the tweeter assembly, under the grille) to get the

most natural balance of sound throughout the listening area.

Install the grille by placing it into the recess and pushing it

in gently.
