LRF-04 Sound Level Logger/Limiter
|Datasheet and Specifications|
The LRF-04 frequency filter sound level logger/limiter spectrally controls the entire sound chain in octave bands. The unit consists of an integrating-averaging frequency band (octaves) sensor and an attenuator of over 40 dB, which functions by analysing and calculating the power of the octaves in real time, taking full advantage of the insulation of the room and achieving maximum sound pressure without either disturbing the neighbours or modifying the reproduction quality (it is not a compressor).
The roomÂ´s sound pressure level, the automatic attenuation level, the date, incidents and the operation mode are permanently displayed on the screen.
The LRF-04 has a permanent memory to store the programming information and data obtained during the past 60 days, even when disconnected from the electricity supply. There is also a battery available to continue storing information for over 1 day without connection to AC power.
NOTE: This model has the Extraneous Noise Override System (ENOS) option, specially designed for the local music reproduction with high ambient noise level: bars, pubs, restaurants etc. The unit does not cut the music. With ENOS, the limiter controls the music so that it never exceeds the programmed limit, regardless of the noise generated by customers
