The SPL2 is the standard version of our sound pressure limiters. It provides the solution to most of your sound problems. This limiter is considered by more and more authorities to be the best in its class.
The SPL2TS is the standard version of our sound pressure limiters. The SPL2TS has a built-in clock. This makes it possible to set different sound pressure levels per part of the day.
However, the SPL3 works like the SPL2 by using a measurement microphone: a microcontroller continuously measures the input level and adjusts the output level as soon as the maximum allowable value is exceeded.
