SM 3 • Setup Guide (Continued)

ATTENTION: Use the appropriate mounting screws. The screw heads must not protrude more than .074” (1.9 mm) above the screw holes in the mounting plate (see the figure below left). If the screw head protrudes too far above the mounting plate surface, damage to the speaker may occur when the speaker is attached (see the figure below right).

Mounting to a Wall Stud

1.Install the speaker cables into the wall or conduit before installing the speaker mounting plate. Leave enough slack.

2.Locate the wall stud where the mounting plate will be installed and while positioning the mounting plate on the wall mark the location of two pilot holes using the holes on either side of the mounting plate so that the stud does not interfere with the speaker wire routing, as shown below.

NOTE: A speaker wire access hole (see the figures below) 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.

NOTE: When mounting to surfaces that do not allow wires to be routed from behind (such as on masonry or concrete walls) and the wires are routed to the speakers via a raceway, use the alternate access points to run the wires to the quick connect speaker contacts (see the figures above).

ATTENTION: Use the appropriate mounting screws (see the above ATTENTION).

3.Drill the mounting plate pilot holes and cut the speaker wire access hole, as previously marked.

4.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 illustrations at the top of this page). Besure to observe the correct polarity.

5.Attach the mounting plate to the wall.
