ENGLISH
10. Mechanical and electrical factors need to be considered when installing a professional
audio system (in addition to those which are strictly acoustic, such as sound pressure,
angles of coverage, frequency response, etc.).
11. Hearing loss
Exposure to high sound levels can cause permanent hearing loss. The acoustic pressure
level that leads to hearing loss is different from person to person and depends on the
duration of exposure.
To prevent potentially dangerous exposure to high levels of acoustic pressure, anyone who
is exposed to these levels should use adequate protection devices.
When a transducer capable of producing high sound levels is being used, it is necessary to
wear ear plugs or protective earphones.
See the technical specifications in the instruction manual for the maximum sound pressure
the loudspeaker is capable of producing.
12. To ensure a correct sound reproduction, loudspeaker phase is to be respected
(loudspeakers are connected respecting the amplifier polarity). This is important when
loudspeakers are installed adjacent one another, for instance, in the same room.
13. To prevent inductive effects from causing hum, noise and a bad system working,
loudspeaker lines should not be laid together with other electric cables (mains), microphone
or line level signal cables connected to amplifier inputs.
14. The loudspeaker cable shall have wires (twisted, if possible, to reduce inductive
effects due to surrounding electro-magnetic fields) with a suitable section and a sufficient
electrical insulation. Refer to local regulations since there may be additional requirements
about cable characteristics.
15. Do NOT connect the loudspeaker low impedance (8 Ω) input to 100 V constant voltage
lines.
16. Install this loudspeaker far from any heat source.
17. Do not overload the loudspeaker with too much power.
18. Do not use solvents, alcohol, benzene or other volatile substances for cleaning the
external parts of this product. Use a dry cloth.

ENGLISH
NOTES ABOUT LOW IMPEDANCE CONNECTIONS
-The total loudspeaker impedance must not be lower than the amplifier output
impedance. Note: a loudspeaker total impedance equal to the amplifier output one
permits to get the maximum deliverable power (but an higher loudspeaker impedance
entails less power).
-The total loudspeaker power shall be adequate for the maximum deliverable power of
the amplifier.
-The loudspeaker line shall be short (for long distances, it may be necessary to use cables
with large cross-section wires).
-Always use cables having wires with an adequate cross-section, considering the cable
length and the total loudspeaker power.
-Loudspeaker lines must be kept separated from the mains cables, microphone cables or
others, in order to avoid inductive phenomena may cause hum or noises.
-Use loudspeaker cables with twisted wires to reduce hum caused by inductive effects
due to coupling with electromagnetic fields.
-Do NOT connect the low impedance input directly to 70 / 100 V constant voltage lines.

IMPORTANTE
ATTENZIONE
AVVERTENZE PER LA SICUREZZA

19
ITALIANO
10. I fattori meccanici ed elettrici sono da considerare quando si installa un sistema
audio professionale (oltre a quelli prettamente acustici, come la pressione sonora, gli
angoli di copertura, la risposta in frequenza, ecc.).
11. Perdita dell’udito
L’esposizione ad elevati livelli sonori può provocare la perdita permanente dell’udito.
Il livello di pressione acustica pericolosa per l’udito varia sensibilmente da persona
a persona e dipende dalla durata dell’esposizione. Per evitare un’esposizione
potenzialmente pericolosa ad elevati livelli di pressione acustica, è necessario che
chiunque sia sottoposto a tali livelli utilizzi delle adeguate protezioni; quando si fa
funzionare un trasduttore in grado di produrre elevati livelli sonori è necessario indossare
dei tappi per orecchie o delle cuffie protettive.
Consultare i dati tecnici contenuti nel manuale istruzioni per conoscere la massima
pressione sonora che il diffusore acustico è in grado di produrre.
12. I diffusori devono essere collegati in fase (corrispondenza delle polarità +/– tra
amplificatori e diffusori) in modo da garantire una corretta riproduzione audio,
soprattutto quando i diffusori sono collocati in posizione fra loro adiacente o nello stesso
ambiente.
13. Per evitare che fenomeni induttivi diano luogo a ronzii, disturbi e compromettano
il buon funzionamento dell’impianto, le linee diffusori non devono essere canalizzate
insieme ai conduttori dell’energia elettrica, ai cavi microfonici, alle linee di segnale a
basso livello che fanno capo ad amplificatori.
14. Il cavo per il collegamento del diffusore dovrà avere conduttori di sezione adeguata
(possibilmente intrecciati, per minimizzare gli effetti induttivi dovuti all’accoppiamento
con campi elettromagnetici circostanti) ed un isolamento idoneo.
15. Non collegare l’ingresso a bassa impedenza del diffusore acustico ad una linea a
tensione costante (100 V).
16. Collocare il diffusore lontano da fonti di calore.
17. Non sovraccaricare il diffusore con una potenza eccessiva.
18. Non usare solventi, alcool, benzina o altre sostanze volatili per la pulitura delle parti
esterne; usare un panno asciutto.
