LF010-1

Sound level limiter 1/3 octave band Spectrum analyser and register PRESENTATION The LF010 limiter continues the philosophy of offering the ideal balance between noise control and maximum music quality while also respecting the dynamics of the music and offering clear, distortion-free and uncut music. Thanks to its power, the LF010 measures the existing sound level in the music venue (emission) at up to four points (one main control sensor and up to 3 optional secondary ones) and the sound level transmitted to a neighbouring house, opposite façade or a point outside (reception) thanks to the sound insulation by 1/3 octave between50 Hz and 5 kHz. It also records the time history of these levels and spectra in its memory, as well as any incidents and tampering detected. The LF010 uses the measured levels to control the overall music level (without equalizing) so that the programmed emission and reception limits are not exceeded in the three day/evening/night time zones. The LF010 performs this control using different Attack and Release modes to adapt its performance to live concerts with great dynamics as well as to dance music club sessions. MAIN FEATURES Discos and Clubs Music & Sports Bars Live concerts Music festivals Karaoke Terraces Bars and Pubs Shops Fitness clubs Restaurants Fast food chains Dance academies Hotels Multipurpose rooms Parties with music: weddings, graduations, etc. Clear sound, no distortion or cuts. Maximum music quality. It measures, controls (sound insulation) and records 1/3 octave spectrum from 50 Hz to 5 kHz according to IEC 61260. Full HD video output for HDMI monitors: user-friendly information for the DJ / sound engineer and display of events, promotions and sponsors. Easy installation and programming by a responsive webserver through laptop, tablets or smartphones (Windows, iOs, Linux, Android). Different limitation modes for Attack and Release. Music gap detector and improved ENOS system (no music cuts produced by audience screaming or clapping). Adaptable to any music source: Mixer, mp3 player, computer with multimedia player application, subscription service such as Spotify or professional mixing software. Biannual calendar for programming closing times for public holidays, holidays (Summer) and special public holidays (New Year’s Eve). Class 1 main sensor and up to 3 optional secondary ones. All with serial number and tampering detection and programmable offset.

LF010-2

Sound level limiter 1/3 octave band Spectrum analyser and register It continuously measures and records the sound emission level in the venue and the level of immission in the receiving environment (adjacent house, point outside or opposite façade) thanks to the programmed 1/3 octave band sound insulation (50 Hz to 5 kHz). It measures and records a wide range of acoustic functions: LAeq, LCeq, Sliding LAeq, Expected music level, 1/3 octave band spectrum (50 Hz to 5 kHz). When sensors cannot be placed at the desired measuring point, the LF010 allows you to apply different OFFSETS to each sensor....

Sound level limiter 1/3 octave band Spectrum analyser and register ADAPTABLE LIMITATION AND CONTROL: It enables you to programme different emission and reception limits for the three day/evening/night time zones. It has different control modes for emission/reception and attack/release that can be configured with different speeds (slow/medium/fast). It includes a music gap (silence) detection system that maintains attenuation between song tracks. It incorporates ENOS (Extraneous Noise Override System) system that allows uncut music playback even when public shouting or clapping: Live concerts,...
