Preventec 

PREVENTEC is a company from Lorraine, France, which is situated in Saint-Julien-lès-Metz. It has been specialized in the design and marketing of ACOUSTIC REGULATORS since 1997. These ones are in accordance with the regulations in force since the enforcement of the 98/1143 Decree from the 15th December 1998, which deals with sound levels in the places where amplified music is broadcasted.

 

Preventec, which the French Department of the Environment regularly consults owing to its skills in the field, took part in the elaboration of the Decree and in the events organized by the CIDB (Information and Resource Centre about Noise).

 

Today, many establishments throughout France, such as night clubs,music-type bars, village halls..., are equipped with PREVENTEC regulators. This is a 7-regulator- full range which is proposed through a network of qualified professionals who carry out the sale and the installation of the products throughout France.

 

Since 2003, PREVENTEC has taken advantage of its experience in struggling against noise pollution to launch display and recording devices which meet a much wider demand, especially in the fields of industry, prevention and education.

 

PREVENTEC would also like to thank all the customers who have trusted it up to now. Thanks to their comments, the products are today high-performance, appropriate and upgradable, thus meeting their requirements at best.

 

 

The DEBEA S (Act by cuting the supply of electricity) regulator is mainly intended for places where music amplified in an usual way without set voicing is broadcasted (music-type bars, multipurpose theatres, theatres...). As the voicing is not identified, the regulator can deal with the electricity network (selected plugs) where a possible magnifying channel will be plugged.

 

A sensor (sonometer) fit with an anticamouflage device is detached from the regulator; it calculates the instantaneous level of acoustic pressure in dB(A) (short Laeq). A threshold set beforehand is watched and as soon as this one has been reached, a luminous device is supplied with electricity (eg: revolving light, electronic display board...), prompting the user to turn the sound down . However, if the threshold keeps on being exceeded ( the time during which the threshold can be exceeded is adjustable), the DEBEA S regulator will momentarily cut the supply of electricity (230 Volts) to the sound system or the plugs(the length of the interruption time is adjustable). Once the interruption time has passed by, the supply of electricity is restored, automatically or not (programmable choice of 1 to 5 power cuts before definitive cut), according to the mode that was chosen.

 

The DEBEA SD (Acting by cut) regulator is mainly intended for places where music amplified in an usual way without set voicing is broadcasted (bars, multipurpose theatres, theatres...). As the voicing is not identified, the regulator can deal with the electricity network (selected plugs) where a possible magnifying channel will be plugged.

 

A sensor (sonometer) fit with an anticamouflage device is detached from the regulator; it calculates the instantaneous level of acoustic pressure in dB(A) (short Laeq:1 second) as well as the average level (floating Laeq adjustable from 1 to 10 minutes). A screen-type display unit restores these values and 5 green and red indicator lights indicate when the adjusted average level is neared. Moreover, a detached luminous device directly plugged on the device help to control the voicing. This technique enables the user to permanently display the evolution of the sound scene. So, the regulator will only intervene if the average threshold that must be watched has been reached. The DEBEA SD regulator will momentarily cut the supply of electricity (230 Volts) to the sound system or the plugs(the length of the interruption time is adjustable). Once the interruption time has passed by, the supply of electricity is restored, automatically.

 

The DEBEA DUO (Acting by cut and acting by direct reduce) regulator is mainly intended for places where music amplified from a sound system which is fixed or fit to be moved is broadcasted. This regulator works toning down the sound (fixed sound system) or cutting the power supply to the sound system (sound system fit to be moved) Example of use: a town has a village hall equipped with a sound system but does not want to put it systematically at the public?s disposal.

 

A sensor (sonometer) detached from the regulator calculates the sound level. If he threshold that must be watched is exceeded, a luminous alarm will be activated, prompting the user to turn down the sound down. If the threshold keeps on being exceeded ( the time during which the threshold can be exceeded is adjustable), the DEBEA DUO regulator will momentarily cut the supply of electricity to the plugs (for a sound system fit to be moved) or tone the sound down (for a fixed sound system).

 

The DEBEA S AUDIO (Acting by direct reduce) regulator is mainly intended for places where music amplified in an usual way from a fixed sound system is broadcasted (bars, multipurpose theatres, theatres...). As the sound system is identified, it works by non-gradual toning down of the sound signal, protecting the sound quality.

 

A sensor (sonometer) fit with an anticamouflage device is detached from the regulator; it calculates the instantaneous level of acoustic pressure in dB(A) (short Laeq). A threshold set beforehand is watched and as soon as this one has been reached, a luminous device is supplied with electricity (eg: revolving light, electronic display board...), prompting the user to turn the sound down . However, if the threshold keeps on being exceeded ( the time during which the threshold can be exceeded is adjustable), the DEBEA S AUDIO regulator will momentarily tone the sound system down for a period that can be adjusted. Once the toning down period has passed by, the regulator will automatically return to its initial way of working.

 

The DEBEA SD AUDIO (Acting by direct reduce) regulator is mainly intended for places where music amplified in an usual way from a fixed sound system is broadcasted (bars, multipurpose theatres, theatres...). As the sound system is identified, it works by non-gradual toning down of the sound signal, protecting the sound quality.

 

A sensor (sonometer) fit with an anticamouflage device is detached from the regulator; it calculates the instantaneous level of acoustic pressure in dB(A) (short Laeq:1 second) as well as the average level you want (floating Laeq adjustable from 1 to 10 minutes). A detached screen-type display unit restores these values and 5 green and red indicator lights indicate when the adjusted average level is neared. This technique enables the user to permanently display the evolution of the sound scene. So, the regulator will only intervene if the average threshold that must be watched has been reached. As soon as the level has fallen down again below the threshold adjusted by the fitter, the regulator stops toning the sound down to operate again in normal mode. The DEBEA SD AUDIO was designed not to spoil the sound quality, whatever the circumstances may be.

 

The DEBEA RC (Acting by slow reduce) regulator is mainly intended for places where music is the main line of business, and whose music quality must be protected (music-type bars, multipurpose theatres, theatres...). It continuously controls an average sound level and works by gradually toning an audio sign down, in case the threshold that must be watched has been reached.

In this case, the DEBEA RC regulator will tone the audio signal down to gradually bring it back to the top allowed value. The DEBEA RC regulator enables you to make best use of the system without spoiling the sound by making for an easy use which has rarely been reached. The DEBEA RC regulator proved appealing to DJs and other people working in the music

 

The DEBEA RCB (Acting by slow reduce) regulator is mainly intended for places where music is the main line of business, and whose music quality must be protected (music-type bars, multipurpose theatres, theatres...). It is recommended for the contiguous places which present insulation weaknesses and provoke emergences generally concentrated on the low frequencies. It continuously controls an average sound level as well as the levels that must not be exceeded in the octave bands that have been chosen. Its way of working allows a maximum exploitation of the acoustic pressure level of the establishment, even in difficult cases.

In this case, the DEBEA RCB regulator will tone the audio signal down to gradually bring it back to the top allowed value. It can calculate the different thresholds that must not be exceeded in the octave bands that have been chosen, work instantly in case of emergence and this band after band. The display unit continuously gives visual marks to help the user to make best use of the system by indicating the octave band(s) it is working on.
