SF26CTLP • Setup Guide
This setup guide contains installation information about the SF26CTLP SoundField®XD low-prole 2-way speaker. This speaker
can be installed by a single-trade installation procedure or by a multi-trade installation procedure (see the SF26CTLP User
Guide, available at www.extron.com, for details). The entire assembly is plenum rated.
WARNING: Potential risk of severe injury.Installation and service must be performed by authorized personnel only.
AVERTISSEMENT : Risque potentiel de blessure grave ou de mort. L’installation et l’entretien doivent être effectués
uniquement par un technicien qualifié.
NOTE: Installation of conduit and conduit adapters must conform to all applicable building codes and local ordinances.
Installing the SF26CTLP in a Hard or Suspended Ceiling
1. Remove power from all devices.
NOTE: If the grille is to be painted, see the
SF26CTLP User Guide for more information.
2. Cut a hole for the SF26CTLP. Use the provided
cutout template to outline the hole to be cut in the ceiling
tile, as described below.
a. For a suspended ceiling only: Remove the ceiling
tile, and, on the back of the tile, draw diagonal lines
across it from opposite corners to locate its center.
Mark the intersection where the lines cross.
b. Position the center hole of the cutout template
directly over the center of the tile, marked in step2a
or in the desired location on a hard ceiling.
c. Trace a circle on the ceiling tile or ceiling around the
cutout template.
d. Cut out the circle traced in the ceiling tile or ceiling.
e. Replace the ceiling tile in the ceiling.
3. For a suspended ceiling only: Attach two V-rails
and one C-ring above the hole cut in step 2, as
described below.
a. Assemble two V-rail half sections so that they
become one single piece by fitting the tab of
one end into the slot of the other end. Open the
V-rail until it locks together, as shown. Repeat this
procedure for the other V-rail.
step 2
b. Remove a ceiling tile adjacent to the tile with the
hole.
c. Place both assembled V-rails on the cut ceiling tile
and position them equally on either side of the hole.
The ends of the V-rails go over the ceiling grid.
d. Position the C-ring assembly on the two V-rails so
that the C-ring is centered over the hole.
e. Secure the C-ring to the V-rails using two screws.

-rail
For a hard ceiling only: Fold the C-ring and insert it
into the hole. Then unfold and place over the hole.
4. Route the speaker wires through the ceiling tile hole.
5. Configure the locking arms for thicker ceilings
(optional) (see the figures on the next page).
• Four speaker locking arms are used to secure the
speaker to ceiling tiles up to 2.25 inches (5.72 cm)
thick.
• The locking arms are equipped with removable
inserts that accommodate ceiling tiles of up to 1.5
inches (3.81cm) in thickness.
• For ceiling tiles thicker than 1.5inches, the locking
arm inserts must be removed.

Remove the
terminal cover.
c. Configure the cable/conduit access plate.
• When not using conduit: Route the speaker
wires through the cable clamp.
• When using conduit: Remove the cable clamp
and install the conduit into the access plate
opening. Secure the conduit to the plate with
the locking nut and pull the speaker wires from
the conduit.
d. Strip 0.2 inches (5 mm) from the wire ends.
e. Use one of the following three methods to attach
the speaker wires to the captive screw connector
(depending on the conguration).
Wiring Multiple Speakers in Parallel
When a chain of speakers is wired this way, disconnecting
one speaker does not remove power from the remaining
speakers in the chain.

To remove the insert:
a. Using a screwdriver, rotate the locking arm so that
the insert can be accessed.
b. Use a small screwdriver to pry and separate the
insert from the locking arm.
c. Repeat this process for the remaining three locking
arms.
d. Rotate all four locking arms back into the speaker.
6. Configure the cable/conduit access plate and
captive screw connector, as described below.
a. The cable/conduit access plate has one alternate
hole available, covered by a knockout. This hole
can be used for loop out when using conduit. If this
knockout needs to be removed, do the following:
i. With the cable/conduit access plate still
attached to the speaker, place the tip of a
flat-head screwdriver against the knockout.
ii. Lightly tap the screwdriver with a hammer to
remove the knockout.
b. Loosen the three cable/conduit access plate screws
and remove the cover.

ATTENTION:
• Do not tin the wire leads before installing
into the connector. Tinned wires are not
as secure in the connector and could be
pulled out.
• Ne pas étamer les conducteurs avant de
les insérer dans le connecteur. Les câbles
étamés ne sont pas aussi bien fixés dans
le connecteur et pourraient être retirés.
f. Insert the captive screw plug into the four-pole
receptacle of the speaker.

g. Replace the cable/conduit access plate and tighten
the three screws.
h. Tighten the cable clamp if it was used.
7. Mount the speaker.
The speaker can be installed into rigid material (mineral
tile, gypsum board, sheetrock, etc.) or soft material, such
as berglass.
a. Insert the speaker through the bottom of the hole in
the ceiling tile that was cut in step 2 on page1
with the wires out of the way.
b. Clamp the speaker to the C-ring by using a Phillips
screwdriver to tighten the four locking arms to the
C-ring.
NOTE: The screw hole
locations are marked
on the front baffle
with a Phllips head
screw symbol. Use
these holes to
tighten the locking
arms.

NOTE: Each of the four locking arm screws
uses an Opti-TorqueTM indicator. The indicator
releases a red plastic ring onto the screwdriver
once the screw is tightened to the correct
torque. Stop tightening any further when this
occurs to avoid overtightening the locking
arms to the C-ring.
ATTENTION:
• To avoid damaging the speaker, do not
overtighten the four locking arm screws.
• Pour éviter d’endommager l’enceinte, ne
serrez pas trop les quatre vis.

Tightening the locking arms into soft material:
Because berglass ceilings and other soft materials
are not as rigid as mineral tiles and other hard
materials, the Opti-Torque indicator should not to
be used as a tightening guide due to the risk of
overtightening.

ATTENTION:
• When setting the taps for a distributed (high
impedance) system, do not tap the system
above the rated power of the amplifier.
• Lors de la mise en place des capteurs pour
un système distribué (haute impédance),
n’exploitez pas le système au delà du niveau
d’alimentation de l’amplificateur.
• When connecting multiple speakers in 8-ohm
mode, be sure that the combined rated
impedance does not equal a value less than
the minimum rated impedance of the amplifier.
• Lors de la connexion de plusieurs enceintes
en mode 8 ohm, assurez vous que le niveau
d’impédance combinée ne soit pas équivalent
à une valeur inférieure à l’impédance minimum
de l’amplificateur.
10. Install the grille. Position the grille so that it covers the
baffle of the speaker. Six small magnets secure the grille
in place.

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 d’altérer
un plafond souple, serrez les bras de
verrouillage pour sécuriser l’enceinte,
en veillant cependant à ce que l’unité
ne cause l’altération de la surface de
montage plane du plafond, comme illustré
ci-dessous.

8. If required, attach a secondary support line.
a. Connect a secondary support line to the support loop
on the back of the speaker enclosure, as shown here.
Anchor the end
to suitable secure
points within the
solid and permanent
building structure.
ATTENTION:
• Do not allow any slack in the secondary
support line.
• Ne laissez pas de mou au niveau du filin
de sécurité secondaire.
b. Replace the adjacent tile that was removed in
step 3b on page1.
9. Set the rotary tap selector switch to the appropriate
setting using a small screwdriver.
