SF 10C SUB Subwoofer • Setup Guide (Continued)

Remove ceiling tile and install suspension cables

1. Determine where the subwoofer is to be suspended and its orientation above the suspended ceiling.

NOTE: Remember that the sound from the unit is directed out the port. Therefore, although you can suspend the subwoofer in

any horizontal orientation, the port needs to be pointed into the listening space.

Consider the following as you make this determination:

Do not install the C-ring

beyond the edge of ceiling tile

• The size (length and width) of the subwoofer.

• The desired location of the woofer port. Ensure that the center of the port

tube will be at least 5-3/16 inches (13.7 cm) from the edge of suspended

ceiling tile once that tile is installed.

NOTE: This positioning ensures that the grille adapter and C-ring fit

properly once installed (see the figure at right).

• Any obstructions above the suspended ceiling that could constrain the

orientation of the suspended subwoofer.

2. At the location where the subwoofer is to be installed, remove as many ceiling

tiles as necessary to install the subwoofer.

NOTE: The number of tiles to remove depends on the height of the structural ceiling above the suspended ceiling, given the

10-degrees spread from the subwoofer to the structural ceiling.

3. At an approximate angle of 10 degrees out from each corner of where the subwoofer will be installed, mark and drill

four holes in the structural ceiling for the suspension cable anchors.

4. Screw a lag eye bolt (or an appropriate anchor) into each hole.

5. Thread the loose end of the suspension cable through the bolt eyehole, pass the loose end of the cable through the

looped end and tighten. Allow each cable to hang.

Suspend the main subwoofer enclosure from the ceiling

ATTENTION: The SF 10C SUB is heavy, approximately 38 pounds (17 kg), and bulky.

ATTENTION : La SF 10C SUB est lourde, et pèse environ 17 kg (38 livres), et est volumineuse.

• Use at least two people to install the subwoofer: one person to lift the unit into position AND to hold it, the second person to

fasten the suspension cables.

• Il faut au minimum deux personnes pour installer le caisson de grave : la première pour mettre l’unité en place ET la tenir, et la

seconde pour raccorder les câbles de suspension.

• Consider using a scissor-lift or other lifting apparatus rather than a ladder to work in the ceiling.

• Songez à utiliser une nacelle élévatrice ou tout équipement similaire plutôt qu’une échelle pour travailler au plafond.

• Do not rest the subwoofer on the ceiling grid, even temporarily.

• Ne posez pas le caisson de grave sur la grille de plafond, même temporairement.

TIP: If a scissor-lift is not available, the speaker can be hoisted using the suspension cables.

1. Remove the grommets from all four corners of the subwoofer frame

Thread the cable down through the cable gripper, through the eye

of one of the eyebolts, and back up through the lock.

(see the figure at right).

2. Install the included eyebolts through the provided countersunk

washers and into the four holes on the frame. Secure the eyebolts

in place with the provided locking nuts.

3. With the help of at least one other person, carefully lift the

subwoofer enclosure into the installation location.

4. Pass the loose end of one of the cables down through one hole of

an included cable gripper. Ensure that about 12 to 15 inches (30 to

38 cm) of cable has exited the gripper.

5. Pass the loose end of the cable through the eye of one of the eye

bolts on the subwoofer enclosure and then through the other hole

in the cable gripper. Ensure that at least 1 inch (2.5 cm) of cable

comes through the other end of the gripper.

WARNING:

AVERTISSEMENT :

• Maintain at least a 2 inch (5 cm) clearance between the

plunger on the cable gripper and any other object in

the ceiling space. This includes the space between the

eyebolt below the gripper and the mounting hardware

above the gripper. If an object strikes the plunger, the

cable gripper could disengage and allow the subwoofer

to fall.

• Conservez au minimum 5 cm (2”) d’espace libre entre le

piston sur le serre-câble et tout autre objet se trouvant

dans l’espace plafond. Il s’agit de l’espace entre l’anneau

de levage sous le serre-câble et le matériel de montage

au-dessus du serre-câble. Si un objet heurte le piston, le

serre-câble pourrait se desserrer et entraîner la chute du

caisson de basses.

6. Repeat steps 3 and 4 for each corner.

7. Adjust the cable tension through all cable grippers so that the subwoofer appears level to the critical eye and to ensure that its bottom

brackets will be approximately 1 inch (2.5 cm) from the top surface of suspended ceiling tile once that tile is installed.

NOTE: The exact height of the subwoofer is not critical at this point. You will make nal

adjustments after the grille is installed.

Threaded rod installation

Secure the subwoofer to the structural ceiling using threaded rods as follows:

NOTES:

• Extron recommends 1/4-inch or 3/8-inch diameter threaded rods for installing this product.

• The threaded rod should be properly secured to the ceiling structure. For example, properly

fasten a unistrut to the ceiling structure and attach threaded rods using nuts and washers.

1. Fasten four threaded rods to the support structure. Extron recommends fastening the rods to

unistruts, one over each corner of the subwoofer installation location (see the figure at right).

2. Fasten a rod to each corner securing point of the subwoofer with nuts and washers.

3. Adjust all the nuts that secure the subwoofer to the ceiling so that the subwoofer appears level to

the critical eye and to ensure that its bottom brackets will be approximately 1 inch (2.5 cm) from

the top surface of suspended ceiling tile once that tile is installed.

NOTE: The exact height of the subwoofer is not critical at this point. You will make nal

adjustments after the grille is installed.

Insert threaded

rods through holes

on the ends of the

mounting bracket.

Attach washer and nut and secure.

Mounting the Port Tube

1. Orient the port tube so that it is pointed into the listening

space (see the image at right).

2. Using the included hardware, attach the port tube to the

speaker.

Installing the Grille

1. If not already accomplished, on the installation surface,

mark where the center of the port tube faces the

installation surface. The center mark must be at least

5-3/16 inches (13.7 cm) from the edge of the installation

surface.

NOTE: For ceiling tile installation, if the ceiling tile is

not removed for the subwoofer installation, remove it.

2. If not already accomplished, using the included grille

cut-out template, mark and cut the hole in the surface.

3. For ceiling tile installation, replace the ceiling

tile in the grid.

4. Place the C-ring on the subwoofer side of the

installation surface and center it over the hole

(see the image at right).

5. Place the grille adapter on the opposite side

of the installation surface and use a Phillips

screwdriver to turn the three locking arms to

loosely mate the adapter to the C-ring.

6. Rotate the C-ring and grille adapter such that

the locking arms and the C-ring do not touch

the subwoofer.

7. Use a Phillips screwdriver to tighten the three

locking arms to clamp the adapter to the

C-ring.

ATTENTION:

• To avoid damaging or deforming soft ceiling material, tighten

the locking arms to secure the speaker, but short of causing the

speaker to deform the flat mounting surface of the ceiling, as seen

from below.

• Afin de ne pas endommager ni altérer un plafond souple, serrez les

bras de verrouillage pour sécuriser l’adaptateur en grille, en veillant

cependant à ce que l’unité ne cause l’altération de la surface de

montage plane du plafond, comme illustré ci-dessous.

NOTE: For installation in rigid vs. soft material:

• Rigid material — Three locking arm screws use Opti-Torque indicator rings that snap

and separate from their plastic rings when the screws are tightened to the correct torque.

The indicator ring falls down the screwdriver shaft. When this occurs, stop tightening the

screw to avoid overtightening the locking arms to the C-ring (see the image at right).

• Soft material — Because fiberglass ceilings and other soft materials are not as rigid as

mineral tiles and other hard materials, the Opti-Torque indicator should not be used as a

tightening guide due to the risk of overtightening (see the ATTENTION, above).

Locking Arms

8. Affix the magnetic grille to the grille adapter.

9. Adjust the position of the subwoofer relative to the installation so that the subwoofer appears level to the critical eye and is centered

over the grille. Ensure that the port tube is as close as possible to the installation surface without touching it.

NOTE: Do not allow the port tube or any part of the subwoofer to touch the installation surface. Undesired audio vibrations can

occur.

Connection and Operation

Congure the cable conduit access plate and captive

screw connector as follows:

1. Loosen the cable conduit access plate screw and

remove the plate before wiring the subwoofer (see

the figure at right).

2. Configure the cable conduit access plate, using

either of the following methods:

• When not using flexible conduit: Route the

speaker wires through the cable clamp (see

figure1,

• When using flexible conduit: Remove the

cable clamp and install the flexible conduit into

the plate opening. Secure the flexible conduit

to the plate with the locking nut and pull the

speaker wires from the flexible conduit (

Extron Safety and Regulatory Compliance Guide on the Extron website.

NOTES:

• The length of exposed wires is important. The ideal length is 3/16 inch (5 mm).

• If the stripped section of wire is longer than 3/16 inch, the exposed wires may touch, causing a short circuit.

• If the stripped section of wire is shorter than 3/16 inch, wires can be easily pulled out even if tightly fastened by the

captive screws.

• Do not tin the leads before installing them in the connector. Tinned wires are not as secure in the connector and could be

pulled out.

4. Connect four or two speaker wires to the captive screw connector by one of two methods, as shown in the following two examples:
