CESVA Octave Band Sound Limiter/Recorder

CESVA Sound Limiter Model LRF04f

for pubs, clubs and venues

The LRF-04f frequency filter sound level logger-limiter spectrally controls the entire sound chain in octave bands and is particularly suited for applications in cafes, pubs, clubs and large entertainment venues. 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. (The limiter is not a compressor.)

The room´s sound pressure, the automatic attenuation level, the date, incidents and the operation mode are permanently displayed on the screen. The LRF-04f 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. The optional DL3E external display allows the DJ to see the live levels and amount of reduction applied by the system.

Software

CESVA SFTL04 Software is a comprehensive software application that allows you to: display numerically and graphically data registered by LRF-04 and choose the displayed interval, generate reports of the data supplied by the software, personalize these reports by writing a maximum of 50 characters as a footnote, study in detail all the sound levels and incidences, acquire data via Modem, display, in real time, the data measured by the LRF-04, program all the parameters of the LRF-04 on just one screen and erase the LRF-04 memory.

SFTL04 software shows the Time History data and the time representation of incidences, this way it is possible to study, in detail, what happens in the establishment, the sound levels produced, or if the sensor has been tampered with and when.

SFTL04 software provides a convenient, user-friendly environment for obtaining, in digital format, the sound data acquired by the LRF-04.
