1. SAFETY INSTRUCTIONS

1.1. Read Instructions — Before connecting and using the equipment, please read this Instruction

Manual carefully and keep it for future reference.

1.2. HEED ALL WARNINGS — Always follow the precautions provided on this EAW Commercial

product and in the instruction manual.

1.3. Water and Humidity — Do not use this EAW Commercial product near water; for example, in the

vicinity of a bath tub or sink, in a damp cellar, near a swimming pool, etc.

1.4. Foreign Bodies and Liquids — Be careful not to allow any foreign bodies or liquids to get into this

EAW Commercial product.

1.5. Servicing — The user should never attempt to make any repairs on this EAW Commercial product

unless otherwise indicated in the instruction manual. All repairs should be made by qualied service

technicians.

1.6. Installation — Do not install this EAW Commercial product in any way that is not provided for in

the instruction manual.

1.7. Respect the Safety Standards — The entire sound system must be designed in compliance with

the current standards and laws regarding electrical systems.

1.8. Specications — When installing and using this EAW Commercial product, keep in mind the

technical specications indicated in the dedicated section of the manual.

1.9. Accessories — Install and use this EAW Commercial product only with the accessories specied

by the manufacturer or supplied with the product.

1.10. Hearing Loss — Exposure to high sound levels can cause permanent hearing loss. The sound

pressure level which leads to hearing loss varies considerably from one person to another, and depends

on the duration of exposure. The U.S. Government’s Occupational Safety and Health Administration

(OSHA) has established the maximum sound pressure levels that can be with stood without causing

damage, which are shown in the table below. According to the OSHA regulations, any exposure over

the maximum limits indicated in the table can reduce the hearing capacity of a person. To prevent

potentially dangerous exposure to high sound pressure levels, anyone subjected to such levels must

use suitable protection. When a EAW Commercial product capable of producing high sound levels is

being used, it is therefore necessary to wear ear plugs or protective earphones when the limits shown

in the table are exceeded.

Consult the specications provided in the instruction manual to know the maximum sound pressure

(SPL) the speaker is capable of producing.

3. INTRODUCTION

The SMS3 and SMS3W are a compact two-way loudspeaker system designed for constant-

voltage. The 4.75” (120 mm) carbon ber woofer, in combination with a 0.5” (13 mm) mylar dome

tweeter mounted on a 110° x 100° constant directivity horn, provide natural, smooth sound

reproduction, ideal for use in business music systems and indoor/outdoor background music

applications. The passive crossover is designed to reduce heat dissipation and optimize the

power response of the loudspeaker. Connections are made to recessed, color-coded spring-loaded

terminals. The enclosure is constructed of high-density plastic, with M6 threaded inserts for use

with the optional mounting hardware, and includes a protective perforated steel grille.

4. INSTALLATION

The special hexagonal shape of the cabinet makes it possible to

position the speaker in various ways, as shown in the gure. The

logo plate on the front protective grille can be rotated to adapt

it to the position of the speaker. The speaker body has four M6

threaded inserts, one each on the top and bottom and two on the

back, used for attaching accessories for installing the speaker in

different ways.

SMS3 (SMS3W) speakers are supplied with a black (white)

ball joint support for wall mounting.

WARNING: Consult a professional rigger or structural

engineer prior to suspending loudspeakers from a

structure not intended for that use. Always know the

working load limit of the structure supporting

the loudspeaker array. Always make sure

that the rigging hardware minimum rating is

at least ve times the actual load.

5. REAR PANEL FEATURES

AND CONTROLS

This rotary control selects the power tap for the internal

constant voltage transformer. Choices are 1W, 2.5W, 5W,

10W, 20W, and BYPASS (used for 4 ohm operation).

2. This rotary control selects the constant voltage

distributed system in which the speaker is used.

Choices are BYPASS (used for 4 ohm operation), 0 (Off), 25V, 50V, 70V and 100V.

Note: Use a slot-head screwdriver to adjust the rotary controls.

6. CONNECTIONS

The spring-loaded speaker terminals are designed to accept

bare wire, up to a maximum of 18 gauge. Strip 1/4’’ (6 mm)

of insulation off the end of the speaker wire, press in the tab,

and insert the bare wire into the hole. When you release the

tab, the wire is locked in place. Make sure there are no stray

strands of wire outside the terminal connection.

WARNING: To prevent the risk of electrical shock,

always fit the protective cover over the terminals after completing the connections.

1) Measured on axis in the far eld with 1 watt (2.00 V rms @ 4 ohms) input and referenced to 1 meter distance using the inverse square law. Listed

sound pressure represents an average from 300 Hz to 3 kHz.

2) The specications provide three power values, which are determined by submitting the speaker to a series of laboratory tests lasting two hours

each. In the test for Applicable Power, pink noise is applied in the operating range of the speaker, and the signal is ltered at the ends of the band

with a 12 dB/octave slope. The applicable power value indicated is an rms value. The signal peaks present in the pink noise, adjusted according

to the type of speaker being tested (e.g., +4.5 dB with respect to the average level), are used for determining the Peak Power value. To identify the

Musical Power, the rms power value obtained in the rst test is doubled, applying it with impulses lasting 0.5 seconds (0.5 sec ON), and at an interval

of 0.5 second between one application and the next (0.5 sec OFF). For all the tests, the maximum power that the speaker can withstand without sus-

taining permanent damage is assumed as the power value.
