SM 3 • Setup Guide
This setup guide contains installation information about the Extron SM 3 speaker.
Installing the Speaker Mounting Plate
The SM 3 speaker comes with two types of speaker mounting plates:
0° mounting plate — The 0° plate allows the speaker to be mounted at on a vertical wall with the speaker protruding less
than four inches (ADA compliant) from the wall surface.
10° mounting plate — The 10° mounting plate allows the speaker to be installed at a 10 degree angle so that the speaker
can be pointed down from an elevated position.
The mounting plate can be installed vertically or horizontally as shown
on the right.

NOTE: Observe all applicable building codes and local ordinances when installing the speaker.
Mounting to a Wall Box
1. Route the speaker cable through the rear of the mounting plate and attach the wire ends to the quick connect contacts using
a small screwdriver (see the following gures on the next page). Be sure to observe the correct polarity.
NOTE: The positive (+) connector and the negative (-) connector are marked on the mounting plate.
2. Attach the mounting plate to the wall box, using two mounting screws (see gure below).
NOTE: The mounting screw holes in the mounting
plate allow for some degree of play and lateral
movement so that the mounting screws may
be aligned properly with the screw holes of the
wall box. Observe U.S. and European screw
locations, as shown on the right.
ATTENTION: Make sure that the wall box is
secured to the wall structure and can handle the
weight of the speaker. If there is doubt, secure
the mounting plate with additional mounting
screws. The wall stud mounting holes can be
used for this purpose.
