The MRC Audio EQLimit sound limiter helps bars comply with council regulations

This system allows you to analyze the electrical signal that reaches the mixing console and the acoustic signal to comply with the regulations of the Madrid City Council in leisure and entertainment establishments., like the Xaloc cocktail bar.

The Xaloc drinks bar, located on Huertas Street in Madrid, has a license to carry out activities with sound or audiovisual reproduction or amplification equipment and its foreseeable sound levels are up to 95 dBA. To be able to control it, you have installed a frequency sound limiter EQLimit from MRC Audio.

The limiter has been installed between the mixer and the power stages, and has a microphone that measures the sound pressure level, analyzing the electrical signal that comes from the mixing console and the acoustic signal. This allows the output level to be adjusted so that it does not exceed the maximums configured on the device. Besides, allows you to store sound level data for each session, as well as possible manipulations of the system and re-programming.

This installation has been carried out by the Telco technical team, also providing its connectivity solutions to ensure the correct functioning of the entire audio reproduction chain..

Regarding the regulations, Each municipality takes measures against noise pollution to comply with the new national noise law, requiring the installation of a controller or limiter., but it does not imply that the sound is always lowered or that there are sudden cuts in the music, You just have to have greater control and make the equipment sound at the right level..

MRC Audio EQLimit

The EQLimit allows you to control two measurement points using two different microphones, applying weights “C” “A” o “BASS”. It is possible to choose the audio level control system from the microphone signal or the audio output, and in both cases globally or by frequencies.

The control signal is compared with preset levels measured on the display. In the case of limitation, according to schedule, no matter how much the input signal or the amplification of the power stages is increased, the level in the room will not exceed the threshold set. The action of the limiter is indicated by a series of LEDs marked with 5, 10, 15 from 20 dB attenuation. Although it does not indicate above these amounts, The equipment will continue to limit even if the signal is increased more than 60 dB.

The limitation circuit is one of the advantages of this equipment since its design imposes a maximum level but without sudden cuts in the music and without the usual pumping effects or breathing sounds., achieving great quality in listening, even at high attenuation levels.

It has a global and fixed attenuation adjustment for both channels, so that it is possible to adapt the maximum level of the amplifier chain with the real work level required, avoiding having to reduce that difference only with active limitation. This ensures a maximum sound level even if for some reason the equipment does not normally limit.
