SNA50-2 OLD

Archives - Sound level control - Unit or Rack

The audio regulation process does not corrupt the signal dynamics as will done an ordinary limiter or compressor.

The audio pressure measure is sent to the computer which includes the very soft audio peaks (with adjustable attack and decay times).

This process results in a maximum average audio level equal to planned one, without any perceptible effect for the listener. Sound and transparency are preserved.
