The LRF-05 frequency filter sound level logger-limiter 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 neighbors or modifying the reproduction quality (it is not a compressor).
The LRF-05 has a permanent memory to store the programming information and data obtained during the past 60 days, even when disconnected from the electricity supply.
The LRF-05 is equipped with an internal self-checking system that allows you to continually detect whether the measurement system (sensor) or the hi-fi equipment have been tampered with. The system also memorises the results obtained during the checking process.
A luminous remote display may be connected to the LRF-05, allowing you to observe in real-time the measured sound pressure level together with the attenuation level applied by the LRF-05.
NOTE: This model has the option ENOS (Extraneous Noise Override System), specially designed for the local music reproduction with high ambient noise level: bars, pubs, restaurants,etc. IT DOES NOT CUT THE MUSIC. With the ENOS, the limiter controls the music so that it never exceeds the programmed limit, regardless of the noise generated by customers.
SFTL05 is the software supplied with the LRF-05 limiter and allows you to: download data saved by the limiter, programme all the parameters from the LRF-05 by modem, in this way, through a PC the limiter can be programmed from anywhere, display in graphic and numerical mode the limiter data, create reports of the data supplied by the software, define the start and end date of the data that will appear in the report and to write the footnote on the report to make it personalized, erase the LRF-05 memory, show in real time the sound levels measured by the sensor together with the attenuation, (if there is any), the disconnection indicators ,and session. This function is very important as the limiter does not have an integrated LCD display.
SFTL05 shows the Time History data and the time representation of incidences. This allows you to study, in detail, everything that occurs in the establishment, the sound levels produced, if the instrument has been tampered with and when it happened.
SFTL05 provides you with a convenient, user-friendly environment for obtaining, in digital format, data acquired by the LRF-05. The SFTL05 is completely indispensable for programming the limiter because some models do not have display or keyboard.
