About this Guide

This guide describes the installation and set up of the SB 33 A Series Speaker.

NOTE: Observe all applicable building codes and local ordinances when installing the

SB 33 A speaker.

In this guide, the terms “speaker” and “sound bar” are used interchangeably to refer to the

SB 33 A Series Sound Bar Speaker.

Product Description

The SB 33 A is an adjustable-width sound bar speaker for use in small-to-medium

conference rooms. It will feature two 3" full range speaker speaker drivers, driven by an

internal amplifier module. The SB 33 A speaker accepts balanced and unbalanced stereo

input signals on three individually buffered inputs.

shelf and window with a built-in door. It can also be configured to mount a PTZ camera with

optional shelf, or configured for no camera with the optional blank center grille. The SB 33 A

sound bar enclosure is adjustable to match the width of the display and is mounted under

the display. The SB 33 A will be offered in four different sizes to accommodate screen sizes

from 46" to 80", as shown in the table below.

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.

Left Speaker ModuleCenter

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

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.

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

marked in step one.

NOTE: If you drill the pilot hole too shallow, the screw head might break off while

it is being fastened into the hole.

ATTENTION:

• When attaching either speaker assembly or the center section to the wallplate, avoid

damaging or scratching the speaker assembly and center section cover.

• Lorsque vous xez les enceintes ou la section centrale à la plaque murale, prenez garde

à ne pas endommager ni à rayer les enceintes et le couvercle de la section centrale.

1. Hook the top clasp edge of the left speaker assembly over the top rail 1 in figure 11 of

the wallplate and slide it to left end of the wallplate 2 so that the left end of the speaker

assembly is aligned with the left end of the display.

Tighten the 2 set screws 3 on the bottom of the left speaker assembly to the bottom

rail of the wallplate.

ATTENTION:

• Always use a power supply supplied by or specied by Extron. Use of an

unauthorized power supply voids all regulatory compliance certication and may

cause damage to the supply and the end product.

• L’utilisation d’une source d’alimentation non autorisée annule toute certication de

conformité réglementaire, et peut endommager la source d’alimentation et l’unité.

• The installation shall be in accordance with the applicable provisions of National

Electrical Code ANSI/NFPA 70, article 725 and the Canadian Electrical Code part1,

section 16.

• Cette installation doit toujours être conforme aux dispositions applicables du Code

américain de l’électricité (National Electrical Code) ANSI/NFPA 70, article 725, et du

Code canadien de l’électricité, partie 1, section 16.

• The length of the exposed wires in the stripping process is critical. The ideal length

is 3/16 inches (5 mm). Any longer and the exposed wires may touch, causing a short

circuit between them. Any shorter and the wires can be easily pulled out even if

tightly fastened by the captive screws.

• La longueur des câbles exposés est primordiale lorsque l’on entreprend de les

dénuder. La longueur idéale est de

5 mm (3/16 inches). S’ils sont trop longs, les câbles exposés pourraient se toucher

et provoquer un court-circuit. S’ils sont trop courts, ils peuvent être tirés facilement,

même s’ils sont correctement serrés par les borniers à vis.

NOTE: Do not tin the wires. Tinned wire does not hold its shape and can become loose

over time.
