Installation
Topics covered in this section of the guide include the following:
• Installation Overview
• Mounting Instructions
• SMK V SB 33 VESA Mounting Kit
Installation Overview
The installation of the SB 33 A speaker includes using the included wallplate to mark the
wall where the SB 33 A will be mounted. After the wallplate is attached to the wall the
SB 33 A is then attached to the wallplate. The following section describes the mounting
procedure for safely and securely mounting the speaker.
NOTE: Install the wallplate onto wall material using common installation methods with
applicable hardware dictated per local building code.
Mounting Instructions
WARNING: Risk of personal injury or property damage. The final installation
should be able to continuously support the speaker weight. The final installation
should also be able to support any short term overloading. Since applications can
vary considerably, it is assumed that the installer will exercise good judgment when
selecting the mounting location, method, and hardware. Installation and service must
be performed by authorized personnel only.
AVERTISSEMENT : Risque de dommages corporels ou matériels.
L’installation finale doit pouvoir supporter en permanence le poids de l’enceinte.
L’installation finale doit également supporter toute surcharge temporaire. Étant donné
la possibilité d’évolution considérable des applications, il est supposé que l’installateur
fera preuve de discernement lors de la sélection de l’emplacement, du mode, et
du matériel de montage. L’installation et la maintenance du système doivent être
exclusivement effectuées par le personnel autorisé.
NOTE: Observe all applicable building codes and local ordinances when installing the
SB 33 A speaker.
SB 33 A Series User Guide • Installation 4
Installing the Wallplate on a Non-masonry Wall
NOTE: When attaching the wallplate to masonry, see Installing the Wallplate on a
Masonry Wall in the following section.
1. Position and level the included wallplate (see figure 4) under the display screen (see
figure 5) and mark the locations of the wall studs through the top vertical slots and
bottom horizontal slots where screws (not included) will secure the SB 33 A speaker
wallplate to the wall.
NOTES:
• If the wallplate cannot be attached to two studs, the wallplate can be offset
such that one side of the wallplate can be attached to one stud and the other
end of the wallplate can be attached to the wall using two (not included)
1/4" Kap Toggles. If the stud must come down the middle of the wallplate,
secure the wallplate to the stud using two screws and to the wall using two
(not included) 1/4" Kap Toggles (one on the leftmost top slot and one on the
rightmost top slot)
• The center of the wallplate does not need to be precisely aligned with the
center of the display above it because the speaker module on either end of the
wallplate can be adjusted on the wallplate.
2. If necessary, cut a hole in the wall to route cables to the SB 33 A speaker.

Figure 5. Display Screen and SB 33 A Alignment
NOTE: Assuming that the display screen is level, allow for some space between
the bottom of the display screen and the top of the speaker because the speaker
assemblies and the center bracket attach to the wallplate by hooking the top
mounting clasps of the speaker assemblies and center bracket over the top
mounting rail of the wall plate.
SB 33 A Series User Guide • Installation 5
NOTE: To allow sufficient clearance between the top of the SB 33 A and the display
k
screen above it, allow for at least a minimum clearance of 11/16 inches (17.5 mm)
between the highest part of the top rail of the wallplate and the top of the speaker,
as shown below. The display screen should not encroach into this area above the
top rail.
Minimum clearance between top of wallplate
and bottom of display is 11/16" (17.5 mm).

4. Drill four pilot holes through the marked locations on the wall.
5. Screw the wallplate to the wall studs using four #14 x 1 3/4" self-tapping wood or
metal screws and four 1/4" SAE washers into the pilot holes.
NOTE: Use wood or metal screws depending on whether the studs are wood or
metal.

Installing the Wallplate on a Masonry Wall
Mount the wallplate on a brick, stone, or concrete wall by doing the following:
NOTE: The center of the wallplate does not need to be precisely aligned with the
center of the display above it because the speakers on either end of the wallplate
may still be adjustable on the wallplate.
1. Follow steps 1 to 3 of Installing the wallplate on a non-masonry wall on page 5.
NOTE: Because masonry installation does not involve wall studs, position the
wallplate so that the mounting holes will evenly distribute the weight of the
SB 33 A.
SB 33 A Series User Guide • Installation 7
2. Using a masonry drill bit, drill four pilot holes in the masonry wall at the locations you

NOTE: If you drill the pilot hole too shallow, the screw head might break off while
it is being fastened into the hole.

3. For each pilot mounting hole:
a. Insert a 1/4" x 1 3/4" masonry screw through a 1/4" SAE washer.
b. Position the wallplate over the pilot holes
c. Insert each screw and washer through the wallplate and into the pilot hole.
