Atlantic Technology ICTS-8.3-E Owners manual

Thank you for purchasing Atlantic Technology speaker products. These

unique, TriMode speakers solve myriad surround sound and distributed

We hope you enjoy them to their fullest. Please take a moment to read

these instructions so you can get the most from your speakers.

These speakers are intended for mounting in a ceiling, in material rang-

ing from 0.5 inches to 1 inch thick. They require at least 4-3/8 inches for

the ICTS-6.3e and 4-7/8 inches for the ICTS-8.3e clearance behind the

front sur face of the ceiling

9-5/8 inch es in di am e ter. These speakers will work equally as well in a

wall as in a ceiling, however note that they re quire more mounting depth

than is normal in a 2x4 studded wall.

Use Mono mode when the speaker will play a single

from any wall boundaries (ceiling/wall/corner). Placing any speak er in close

proximity to other boundary surfaces will always “col or” the sound that the

location for most diffuse surround speakers is directly to the sides of

the prime listening area. However, in many rooms there’s simply no

When used in TriVector mode these speakers are best placed in the

position, keeping the tweeter orientation as noted above. There’s a 15

degree “window” of place ment forward or back of the listening po si tion

the diffuse effect. Also note that, due to the low midrange fre quen cies

New Construction and Retroﬁ t Installations

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

available from Atlantic Technology. Please refer to the instructions included

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

ICTS-6.3e: Diameter = 7-7/8 in., 200mm; Depth = 4-3/8 in., 112mm

ICTS-8.3e: Diameter = 9-5/8 in., 245mm; Depth = 4-7/8 in., 124mm

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

the ceiling material can support the weight of the speak er. 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. If it is not, the rotating clamps will be

restricted in their move ment and may not clamp 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 cloth

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

ceiling is void of insulation it will be ben e ﬁ cial to the performance of

the speaker to install an At lan tic Tech nol o gy foam Sound Damping Kit

behind and around the as sem bly.

Depending on the sound mode (mono, stereo 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

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

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

Tweeter Settings

To set the tweeters 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 SUR (see

Fig. 3A). 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. These settings can easily

be changed after the speaker is in stalled (see Fig. 3B).

Attach the previously installed audio feed wires to the ap pro pri ate speaker

terminals. For Mono or TriVector operation ei ther set of input terminals

may be used. For Stereo operation one set of leads is attached to each

set of input terminals. Sim ply remove 1/2 inch of insulation from the

end of each input wire. Push down on the terminal con nec tor and a

large opening will appear in the shaft of the con nec tor 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 4.

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

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

the back of the ceiling and clamp the ceiling between themselves and

the trim ring. See Figure 6.

Snug all four mounting screws in this manner to make a ﬁ rm seal with

the ceiling. Be care ful not to overtighten them.

Start the system and make sure the speakers are operating prop er ly. If

necessary, 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 gen tly.
