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.

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.

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.

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.
