SAROS_IC4T/IC6T/IC8T
Saros® 2-Way In-Ceiling Speakers
Saros® speakers by Crestron® deliver professional grade
performance and flexible installation in a range of popular
sizes for demanding commercial applications. Solid
construction and high end components are hallmarks of the
complete Saros speaker line.
Ideal for use in background or foreground music, paging,
and sound reinforcement systems, Saros speakers are
engineered to achieve smooth, even coverage, high output,
and clear, natural sound quality through the employment of
horn loaded titanium dome tweeters, high efficiency
damped cone woofers, ported enclosures, and precisely
tuned crossovers.
Saros 2-way in-ceiling speakers are available in white or
black and may be painted to blend with the ceiling surface.

Installation
1
Prepare Mounting Hole
Before finalizing the speaker location, check to make sure there are no fixtures, pipes, air ducts,
joists, or other possible obstructions. If applicable, use a good quality stud finder to locate joists.
If there are no obstructions, use the supplied template to trace an outline of the mounting hole.
For drop tile ceilings, remove the ceiling tile and place on a flat surface to trace the mounting
hole. For sheet rock or standard construction ceilings, use the template to trace the mounting
hole directly on the ceiling.
Install Cable
Run the cable from the audio source to the speaker location, observing all appropriate local
codes. Strip the ends of the speaker cables approximately 1/8” to 3/16” (~3 mm to ~5 mm) and
twist the strands
.
Install Tile Bridge
The included tile bridge components provide proper support when the speaker is installed in a
typical drop tile ceiling. Refer to the illustration below.
1. Based on the location of the mounting hole determined in “Prepare Mounting Hole” above,
use the two supplied screws to attach the support ring to the fully extended rails so that
when installed, the ring is aligned with the mounting hole and the rails rest on the ceiling
grid frame.
2. The support ring position on the rails is adjustable to enable off-center speaker positioning.
The tile bridge assembly can be folded to fit through the speaker cutout in blind-mount
situations.

Install/Remove Grille
The zero-bezel frameless grille is held in place by powerful magnets. A safety tether is included to prevent
any possibility of the grille falling from the ceiling. With the tether attached, place the grille in position on
the speaker. To remove the grille, grip the edges and pull away from the speaker.
Paint the Speaker Grille
Speaker grille painting should be done prior to mounting.
1. Carefully remove the material on the underside of the grille and set it aside for reinstallation. It may be
necessary to use a knife or other sharp instrument to free an edge of the material so it can be peeled
away. Use care to avoid cutting or tearing the material.
2. Dry brush or lightly spray the surface to be painted. Use care to avoid clogging the holes in the grille.
3. Once the paint is dry, reinstall the material to the underside.
Mount/Remove Speaker
The in-ceiling speaker includes four toggle clamps that simplify the mounting process. If the grille is mounted
on the speaker, remove it before proceeding. (Refer to “Install/Remove Grille” above.)
1. Refering to the illustrations to the right, remove the screw securing the rear cover panel, and lift the cover
panel off to expose the supplied terminal block.
2. Route the speaker cable through the cover cable clamp and connect the wires to the terminal block,
using the outer IN terminals; red to + and black to –. Use the inner + and – THRU terminals to connect a
pass-through (parallel) speaker.
3. Allow some slack in the speaker cable(s) and position the cover panel on the back, making certain it
engages the mounting clips. Secure the cover panel using the screw removed in step 1 and tighten the
cable clamp to secure the cable(s). Do not overtighten. Use a safety tether attached to the rear enclosure
to prevent the speaker from accidentally falling.
4. The toggle clamps offer two positions to accommodate both standard and extra thick surfaces up to 2.4
inches (61 mm). For extra thick tiles, reset the toggle clamps to the upper position before continuing.
a. With the toggle clamps turned inward, insert the speaker into the opening.
b. Hold the speaker against the ceiling and begin tightening the four screws on the front of the speaker.
The toggle clamps first rotate into clamping position (as indicated in the front view illustration to the
right) and then begin holding the speaker to the ceiling.
c. Tighten the screws until the speaker is secure. Do not over tighten.
5. Speaker removal is accomplished by reversing steps 1 through 3 above.
a. Hold the speaker in position and loosen the front screws to unclamp the speaker. Continue to loosen
the screws until the toggle clamps rotate inward.
b. When the
speaker is loose, carefully lower the speaker from the opening and disconnect the wiring.
Set the Transformer Tap Selector Switch
The speakers are equipped with a 70V/100V matching transformer for distributed audio
systems. The transformer tap selector switch on the front panel is used to set the speaker
power level. Use a flat blade screwdriver to adjust the switch.
1. For SAROS_IC4T 70V systems, use the left side settings and select from 3.75, 7.5,
15, or 30 watts. The X position should not be used.
2. For SAROS_IC4T 100V systems, use the right side settings and select from 1.88,
3.75, 7.5, 15, or 30 watts.
3. For SAROS_IC6T and SAROS_IC8T 70V systems, use the left side settings and
select from 7.5, 15, 30, or 60 watts. The X position should not be used.
4. For SAROS_IC6T and SAROS_IC8T 100V systems, use the right side settings and
select from 3.75, 7.5, 15, 30, or 60 watts.
The switch may also be set to 8Ω operation, bypassing the transformer completely. This
setting should be used only for 8 Ω audio systems.
