The measure of pressure by the acoustic sensor is transmitted in the computer which integrates the points of modulation with a very soft, adjustable slope in rise time and in fall time. This permanent regulation allows to obtain a maximum acoustic average level equal to that programmed in instruction, without its action is perceptible by the listener. The sound and the transparency are so preserved.

Choice of three curves of answer for the acoustic analysis allowing to considered the grave in priority.

Technology: VCA
Ouputs: symmetric compatible Asymmetric
Regulation: either by acoustic sensor, or by the electric analysis of the signal entering the SNA 50 while keeping then the measure of the acoustic level for the history
Card: microprocessor with keyboard and password for the programmings, the calibrations and the started by the installer
