Type of sound system:
- Comfort (musical atmosphere + calls + messages) - Safety (Evacuation certification EN54)
The place to install a sound system:
- Store, restaurant, place of worship, school, supermarket, shopping center, retirement home, aquatic complex, stadium...
The characteristics of the building:
- Surface, partitioning, height, false ceiling, ambient noise, reverberation (echo)
The type of sound content allows you to define the speakers to be used, standard for simple voice messages or speakers with a wide bandwidth to reproduce a good quality musical atmosphere.
Typical speakers:
CSL-603 OD-506FT B PBT 30 BL HS-48 CO 120
A loudspeaker has different powers (20, 10 or 5 W for example), thus offering the possibility to adapt to the ambient noise or the height under the ceiling.
To determine the number of loudspeakers needed for an installation, divide the surface area of the area to put sound by the surface area that a single loudspeaker can cover.
(e.g.: it takes about 5 CSL-603 loudspeakers to put sound a room of 250 m2 knowing that a single loudspeaker covers 45 m2 between 3 and 5 m high).
It is important that the power of the speakers provide good audibility for the ambient noise in the area.
Some information to know:
Mixer amplifier Power amplifier Matrix amplifier
In addition to the installation, the modulation sources (Tuner, MP3, USB, SD or Bluetooth) allow the broadcasting of ambient music or radio if necessary (ER-100CVB, IR-100).
These modulation sources can only be added if the amplifier does not offer this type of function.
USB/SD MP3 CD player, Bluetooth Internet radio tuner
The selection of the microphone depends on its final use, i.e. whether it is for animation, speech, calling or paging.
All types of microphones generally fit most preamplifiers, matrixes, etc.
BE-5018/H-83 UM 915S PA-100X PA-04
The section of the cables depends on the power of the loudspeakers distributed on the line, as well as on the length of the line.
It is also important to know that wiring speakers on a 100V line causes a loss of power along the line. However, this loss of level is hardly felt by the ear.
