About this Guide  
This guide describes the Extron SM 26 surface mount speaker and discusses how to  
install, configure, and operate it.  
In this guide, the terms “SM 26” and “speaker” refer to the SM 26 surface mount speaker.  
About the SM 26 Surface Mount Speaker  
The SM 26 speaker is a surface-mount speaker system that features a 6.5-inch woofer  
and a one-inch tweeter with very wide audio dispersion. Speaker mounting incorporates  
a separate mounting plate that can be attached directly to a wall. The speaker wiring  
attaches to the mounting plate so that the speaker can easily slide into the mounting  
plate, making electrical contact between the plate and the contacts on the speaker. A  
built-in locking mechanism between the speaker and the mounting plate also prevents  
the speaker from being removed by unauthorized personnel. The speaker may be easily  
removed by depressing a hidden release mechanism that does not require tools.  
Features  
Mounting options —  
Flat (0°) mounting plate  
Angled (10°) mounting adapter  
Yoke mount kit (optional)  
Available in two versions —  
SM 26: with 8-ohm input  
SM 26T: with internal transformer and 8-ohm/70V/100V tap selector switch  
6.5-inch woofer with 1-inch tweeter — Full range with a wide audio dispersion.  
Dual tuned bass-reflex ports  
Rated power — 60 W continuous pink noise (per IEC 60268-5); 120 W continuous  
program.  
Frequency response — 70 Hz to 20 kHz, -10 dB (half space)

Color options — Available in black or white finishes.  
Automatic speaker connection — Recessed gold-plated contact pins integrated into  
each speaker automatically make an electrical connection when the speaker is mounted  
to the wall mounting plate.  
Hidden release mechanism — The speaker automatically locks on to the wall  
mounting plate to prevent tampering, but a hidden release mechanism allows the  
speaker to be quickly unlocked without the use of tools.  
Security key — A special key allows the speaker to be locked or unlocked to the  
mounting plate.

Installation  
NOTE: Unless otherwise stated, mounting hardware is not included.  
This section describes the installation and setup of the SM 26 surface mount speaker.  
Topics include:  
Installing the Speaker Mounting Plate  
The SM 26 speaker comes with a flat mounting plate and an adapter for positioning the  
speaker 10° up, down, left, or right.  
0° mounting plate — The flat (0°) mounting plate allows the speaker to be mounted  
flat on a suitable surface.  
10° mounting adapter — The 10° mounting adapter allows the speaker to be  
installed at a 10 degree angle so that the speaker can be pointed up, down, left, or  
right from an elevated position by rotating the adapter.

Mounting to a Wall Stud  
NOTE: Mounting hardware not provided.  
1. Locate the wall stud where the mounting plate will be installed.  
2. If using the 10° mounting adapter, position the adapter to the wall stud according  
to how the speaker will be angled and mark the positions of the pilot holes. See the  
figure below for mounting hole locations.

Mounting the Adapter  
If not using the adapter, position the mounting plate against the wall. The #26 arrow  
molded into the mounting plate indicates the vertical midpoint of the SM 26 speaker  
when it is mounted on a wall stud. While positioning the mounting plate on the wall,  
mark the location of two pilot holes using the holes indicated below.

Positioning the Mounting Plate  
NOTE: A speaker wire access hole (see the figure in step 6) must also be cut in  
the wall, so mark that hole location now with the mounting plate positioned on  
the wall while ensuring that the wall stud does not interfere with the wire routing  
and that the mounting plate hides the access hole.  
3. Drill the mounting plate pilot holes and cut the speaker wire access hole, as previously  
marked.  
4. Install the speaker cables into the wall before installing the speaker mounting plate.  
Leave enough slack in the cable.

5. The SM 26 can be mounted with or without the 10° mounting adapter. In either case  
the wiring of the quick connect contacts remains the same, but the wire routing will  
vary.  
Routing the wires without the 10° mounting adapter  
Route the speaker cable through the rear of the 0° mounting plate and attach the wire  
ends to the quick connect contacts using a small screwdriver, as shown below. Be  
sure to observe the correct polarity.

and washers, as shown below. Then attach the wire ends to the quick connect  
contacts using a small screwdriver, as shown below.

6. Attach the mounting plate to the wall, as shown below.  
ATTENTION: Use the appropriate mounting screws. The screw heads must not  
protrude more than 0.27 inch (7 mm) above the screw holes in the mounting  
plate (see the figure below). If the screw head protrudes too far above the  
mounting plate surface, damage to the speaker may occur when the speaker  
is attached.

Attaching the Speaker to the Mounting Plate  
ATTENTION: By default, the SM 26 speaker is shipped unlocked. When mounting  
the speaker to the mounting plate, be sure that the speaker is unlocked. Failure to  
place the speaker in the unlocked position will result in damage to the speaker lock  
mechanism should an attempt be made to mount a locked speaker (see “Using  
NOTE: If the secondary attachment point is being used, see the “Attaching a  
Secondary Support Cable” on page 9 for installation details before proceeding  
further.  
Position the rear mounting slot of the speaker above the catch tab of the mounting plate,  
then slide the speaker down into the mounting plate until a click is heard indicating that  
the speaker is secured in place (see figure below). When properly seated, the speaker  
connections are automatically made.

Using the Security Key to Lock and Unlock the Speaker  
Insert the key into the center of the speaker grille and turn the key, as needed, so that  
the speaker is in the unlocked position (see the figure below). There are three small raised  
“dimples” (see the bottom figure below) on the grille surface that surrounds the keyhole.  
Repeat this procedure, but set the key to the locked position to lock the speaker.  
ATTENTION: The key must be rotated to the unlocked postion before the speaker  
is attached to the mounting plate. Failure to place the speaker in the unlocked  
position will result in damage to the speaker lock mechanism should an attempt be  
made to mount the speaker.
