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 flat 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.

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 figures 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 figure 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.
