Band of octave limiter in global level
Standard NF S31-122-1-2017

The SNA70-3 is a dual limitation system for global level and per octave band. The implementation technology to the overall sound absolutely no limitation degrades the signal dynamics like a traditional compressor.

The pressure measurement by the acoustic sensor is transmitted to the computer which integrates voice peaks with a very gentle slope, adjustable rise time and fall time.

• No specific software.
• Technology VCA (Voltage Controlled Amplifier), no cut of the audio signal.
• Balanced inputs/outputs compatible unbalanced.
• Limitation in global and per octave band 63Hz, 125Hz, 250Hz, 500Hz (1 KHz, 2 KHz, 4KHz optional)
• Limitation in global level, either by acoustic sensor, or by the electric analysis of the signal entering the SNA70-3 while keeping then the measure of the acoustic level for the history.
• Visualization of levels and parameters on touch screen front panel.
• Real time display Leq1s per band and global level.
• Selecting the A or C weighting for sound analysis of global level, C weighting allowing to take into account the low frequencies in priority.
• Automatic change summer/winter time.
• Embedded Web Server for consulting the history and setting equipment.
• The internal memory is dimensioned to store the values 24 hours a day and 7 days a week,for 6 months.
• USB Host for connecting a USB stick for collecting history.
• Acoustic and electric auto-verification of the measuring sensor.
• SNA70-3 can be sealed.
• According to decree 98-1143, and norm NF S31-122-1-2017.
