Installation Instructions

Thank you for purchasing Atlantic Technology speaker products. These

unique, TriMode speakers solve myriad surround sound and distributed

audio installation problems. We work very hard to ensure that all of

our speakers consistently deliver ex cep tion al performance and value.

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.

Mounting Speciﬁ cations

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

. The mounting opening for the ICTS-6.3e is

7-7/8 inches in diameter. The mount ing opening for the ICTS-8.3e is

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.

Operating Modes and Locations

ono Mode

Use Mono mode when the speaker will play a single

chan nel of information (as

either

the left or right channel of a stereo pair

of speak ers). When used in Mono mode, both tweeters reproduce the same

signal. In Mono mode the speaker can be located anywhere within the

listening area. Generally however, it’s best to keep it at least 24 inches away

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

speaker produces. Even speakers that incorporate frequency ad just ments to

compensate can only make small im prove ments to the det ri men tal effects

of boundary reﬂ ections. The more di rect ly under the speak er you are, the

more high frequency information you will hear. Should you be using two

speakers in Mono mode to re pro duce stereo, consider where the majority

of the room’s occupants will be most

of the time. Then try to locate the

speakers where the lis ten ers will get a

reasonable balance of sound from both

speakers. When wired in Mono mode

the tweeters interact strongly, chang-

ing the dis per sion pattern of the high

fre quen cies as shown in Figure 1.

Important Note:

DO NOT rotate

the tweeter assembly or damage

will occur. To achieve the desired

dispersion pattern, rotate the entire

speaker assembly before mounting.

This can and should be used to your

advantage by rotating the speakers

when you install them in order to

properly align the tweeters. This way

you can exert some control over the

spread of mid and high frequency sound throughout the room and hence

improve the sys tem’s per for mance.

Stereo Mode

In Stereo mode each of the woofer’s dual voice coils and

the tweeters receives their own signals. The result is stereo re pro duc tion

(al be it with limited separation) from a single speaker. This is particularly

advantageous in distributed audio systems where there is a desire to have

stereo sound in many rooms, but with as few speakers as possible. Unlike

so many ceiling speakers, the ICTS-8.3e and ICTS-6.3e use very high

quality com po nent parts and sophisticated designs to deliver ex cel lent

sound quality; sound quality so good that it will surprise you. When

installed as a single point stereo speaker it’s typically best to lo cate the

speaker as centrally within the listening area as possible. Di rect ly in the

center of the room, or in the middle of the prime seating area.

TriVector

™

Surround Mode

TriVector mode puts the two tweet-

ers in each speaker out of phase with each other. The result, when you

sit cen tered on the tweeter array, is a non-localizable sound ﬁ eld that

helps re-create the surround ﬁ eld intended by the movie’s director.

Since the goal of Home Theater is to get you “lost in the mov ie,” a

diffuse surround ﬁ eld almost always works best. To that end the ideal

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

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

place to conveniently place speakers to the sides. Until the introduction

of At lan tic’s TriVector ceiling surrounds, the ceiling was an often used,

but generally less than ideal alternative.

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

ceiling to the sides of the prime listening location, with the tweeters

aimed towards the front and back of the room. You can also place the

speakers to the side and slightly forward or back of the prime listening

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

that is ac cept able. But note that any more forward or back and you’ll lose

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

com ing from the woofer, if you place the speakers directly over the

listening position there will be a fair amount of localizable surround

sound even when the speakers are set to TriVector mode.

New Construction and Retroﬁ t Installations

Note:

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

to Step 2 below.

Mounting Hole Speciﬁ cations:

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.

IMPORTANT:

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

speaker. They are the same for both the ICTS-6.3e and ICTS-8.3e. For Stereo

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.
