10. There are numerous mechanical and electrical factors 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 dura-
tion of exposure. To prevent potentially dangerous exposure to high levels of acoustic pres-
sure, 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 therefore necessary
to wear ear plugs or protective earphones. See the manual technical specifications to know
the maximum sound pressure level.
IMPORTANT NOTES
To prevent the occurrence of noise on line signal cables, use screened cables only and avoid
putting them close to:
- Equipment that produces high-intensity electromagnetic fields.
- Power cables.
- Loudspeaker lines.

- Always use cables having wires with an adequate cross section considering the cable length and the total loudspeaker power 7
- Do not connect the low impedance input directly to 70 100 v constant voltage lines 7
- English 7
- Loudspeakers line shall be short for long distances it may be necessary to use cables with large cross section wires 7
- Loudspeakers lines must be kept separated from the mains cables microphone cables or others in order to avoid inductive phenomena may cause hum or noises 7
- Notes about low impedance connections 7
- Specification 7
- The total loudspeakers impedance must not be lower than the amplifier output impedance note loudspeakers total impedance equal to the amplifier output one permits to get the maximum deliverable power but a higher value entails less power 7
- The total loudspeakers power shall be adequate for the maximum deliverable power of the amplifier 7
- Use loudspeakers cables with twisted wires to reduce hum caused by inductive effects due to coupling with electromagnetic fields 7

- L impedenza totale dei diffusori non deve essere inferiore a quella d uscita dell amplificatore nota l impedenza complessiva dei diffusori uguale a quella d uscita dell amplificatore permette l erogazione della massima potenza mentre un impedenza superiore comporta una riduzione della potenza erogata 13
- La lunghezza delle linee diffusori deve essere ridotta al minimo una lunga distanza può comportare l uso di cavi con sezioni elevate 13
- La somma delle potenze dei diffusori deve essere adeguata alla potenza massima erogabile dall amplificatore 13
- Note sui sistemi con connessione a bassa impedenza 13
- Per evitare che fenomeni induttivi diano luogo a ronzii disturbi e compromettano il funzionamento del sistema i cavi per i diffusori non devono essere canalizzati assieme ai conduttori dell energia elettrica ai cavi microfonici od altre linee 13
- Per minimizzare gli effetti induttivi ronzii dovuti all accoppiamento con campi elettro magnetici circostanti utilizzare cavi con conduttori intrecciati 13
- Utilizzare dei cavi con conduttori aventi una sezione adeguata considerando la loro lunghezza e la potenza complessiva dei diffusori 13
