SAFETY
General instruction
• The products referred to in this manual conform to the European Community Directives and are there-
fore marked with .
• The unit is supplied with hazardous network voltage (230V~). Leave servicing to skilled personnel only.
Never make any modications on the unit not described in this instruction manual, otherwise you will
risk an electric shock.
• Connection must be made to a power supply system tted with ecient earthing (Class I appliance ac-
cording to standard EN 60598-1). It is, moreover, recommended to protect the supply lines of the units
from indirect contact and/or shorting to earth by using appropriately sized residual current devices.
• The connection to the main network of electric distribution must be carried out by a qualied electrical
installer. Check that the main frequency and voltage correspond to those for which the unit is designed
as given on the electrical data label.
• This unit is not for home use, only professional applications.
• Make certain that no inammable liquids, water or metal objects enter the xture.
• Do not dismantle or modify the xture.
• All work must always be carried out by qualied technical personnel. Contact the nearest sales point for
an inspection or contact the manufacturer directly.
• If the unit is to be put out of operation denitively, take it to a local recycling plant for a disposal which
is not harmful to the environment.
WARNING!
Warnings and installation precautions
• This product in combination with amplier, may be capable of producing dangerous sound levels that
could cause permanent hearing loss. Do not operate for a long period of time at high volume level or
at a level that is uncomfortable.
• If this device will be operated in any way dierent to the one described in this manual, it may suer
damages and the guarantee becomes void. Furthermore, any other operation may lead to dangers like
short circuit, burns, electric shock, ect.
• Do not install the xture near sources of heat.
• The xture must be located in a place where a proper ventilation or thermal dissipation is not impeded.
Do not install the xture in a conned space.
• The output level of the amplier must never exceed the marked sensitivity.
• Do not link the output of any amplier channel back into another channel’s input. Do not parallel or
series connect an amplier’s output with any other amplier’s output.
• Make sure that the signal is correctly connected to the amplier’s input channel and set to proper input
mode.
• Please turn o the power switch before pulling o the power cord.
• Before starting any maintenance work or cleaning the unit, cut o power from the main supply.
• When cleaning unit, please do not use solvents such as acetone or alcohol, since they may damage the
of the unit outer nish and the printings on the panels.

- 3- GENERAL CRITERIA FOR INSTALLATION OF SOUND SYSTEMS
Introduction
This guide represents a quick introduction to the criteria for the installation of a sound system at constant
voltage or constant impedance.
A sound system must be made by qualied personnel only, who must evaluate the needs of the user and the
environmental characteristics of the spaces to be covered, select the speakers according to the spaces and
the type of message to be broadcasted (ie: speech / music ), identify the suitable amplier model to drive the
complex of all the speakers and having an adequate number of inputs, evaluate the proper connection for the
speakers and determine the section of the wiring.
Constant voltage systems
In terms of selection of speakers and their connection it’s necessary to evaluate whether to use normal speak-
ers with 4/8/16Ohm impedance or speakers with transformer. The decision is usually inuenced by the desti-
nation of the system (supermarket, disco , pub, house, ...) and by the number of speakers to employ. Constant
voltage speakers are normally used into situations where it is necessary to install several speakers with low
power to get a homogeneous distribution of audio and overall low volume. The classic example is the sound
installation in airports or supermarkets. In these situations several speakers are usually placed within a short
distance between them, normally a volume low enough to not disturb and a frequency covering the entire
area with same sound pressure.
Differences between 4/8/16 Ohms systems and constant voltage systems
The 4/8/16Ohm systems are aected by problems of impedances:
• speakers connected in “series” mode add their impedance (example: 4Ohm + 4Ohm = 8Ohm)
• speakers connected in “parallel”mode divide their impedance (example: 8Ohm // = 8Ohm 4Ohm)
In the following pictures nd a few examples of connections: series, parallel, series + parallel. Also the applicable
powerisreportedaccordingtotypeandimpedanceofeachspeaker.Pleasenotepolarityindicatedforeachspeaker.
Constant voltage systems use speakers equipped with transformer. Normally they can be con-
gured on 2 or more dierent maximum power levels. In this type of system only 2 conduc-
tors are employed: the black one is connected to the negative terminal (usually marked by “0” or
“COM”), the red one is connected to one of the contacts (50V, 70V, 100V). The amplier driving all
speakers will be connected to such 2 wires paying attention that right polarities are respected.
Please note that:
• Voltage selected on speaker transformer must match the voltage selected on the amplier.
• Total sum of speakers power must not exceed power of the amplier.
• To ensure a correct reproduction of the audio signal it is important to setup the connection with no phase
shifts: the connection between positive and negative poles of the amplier must match the polarity on
speaker transformer.
• It is important that cables have an adequate section: increasing total length of the sound installation in-
volves increasing of cable section to avoid distortion or signal loss.
• Cables for connection of the speakers should be passed separately from other electrical or microphone
cables, to avoid ground loops or triggers of any kind.
• It‘s always important to use cables with twisted wires
