The SPL3 works just like the SPL2: the microcontroller continuously measures the input-level and attenuates the output level as much as necessary to keep the sound level below the given threshold.

The SPL3TS has a built in clock/ timer. This makes it possible to program a completely different sound level at different periods of the day. The built in calendar allows you to program a list of 20 dates to switch the limiter to bypass automatically. All these settings can be adjusted by using the PC-software.
