LRS-03
Logger-Limiter Sound Level
Main Characteristics
The logger-limiter LRS-03 measures records and limits the sound pressure level
at the site where it is installed. The LRS-03 is inserted into the reproduction
chain, between the mixing desk and the crossover, intervening in the entire

store information concerning sound levels measured in the establishment and
concerning incidents that occur, (tampering with the equipment), during a minimum period of one month. The LRS-03 allows you to programme the periodicity
of information storage (from 2 min. to 1 h. in 1-min. steps). The information for
each session is also stored, allowing you to demonstrate the sound levels generated by your activity to the authorities. The information stored can be consulted in various ways: displaying it on the LCD screen or printing it by connecting a parallel printer to the corresponding LRS-03’s output port. The information
can also be transferred to a PC via a USB port or modem.
• Registers all incidents, e.g.
disconnection from the mains
or sensor tampering
The LRS-03 allows the programming of different schedules for daytime and for
night-time evaluation and the maximum levels allowed for each schedule. The
LRS-03 also allows you to enter different working schedules, (session sched• Adaptable to any kind of regu- ules), for each day of the week and can fit any kind of establishment.

An illuminated external display can be connected to the LRS-03. This allows
you to consult the sound pressure level measured and the attenuation applied
by the LRS-03 in real time from another point in the room.
