Mechanical Installation
Mounting the clip-fit brackets to the wall:
a. Mount the wall bracket to the desired
surface, in this vertical orientation only.
Note that the bracket has two mounting
holes with vertical spacing that allows
them to be used with a standard wall J-
box.
Two screws are supplied for securing the
wall bracket to a J-box. Install the shorter
6-32 screw in the top hole of the J-box,
and the longer screw in the bottom. Only
screw them in by a few threads initially,
then place the clip-fit bracket over the
screws through the key-hole slots in the
bracket as shown. Tighten the screws once
the bracket is securely in place.
Rotating the loudspeaker’s input section
(if required):
The SMS1990 loudspeaker can be mounted vertically (as
shown) onto the clip-fit bracket, or horizontally. If you want
to change the orientation, follow these steps:
a. Remove the four screws holding the circular input
section in place.
b. Pull out the input section by approximately half an
inch, and rotate it through no more than 90 degrees.
c. Secure the input section into its new position with the four screws.
