The microcontroller in the limiter continuously measures the input signal and attenuates the output as much as necessary to keep the maximum sound pressure below a preset value. Because the SPL limiters are not peak limiters, the dynamics of the music are not affected.
Both the input sensitivity (threshold) and the output attenuation (output level) can be set on the SPL2. All connectors and the controllers can be sealed after installation, so that they cannot be adjusted afterwards.
The SPL2TS is equipped with a built-in clock. This makes it possible to set different sound pressure levels per part of the day. The built-in calendar supports up to 10 dates on which the limiter operates in 'bypass' mode. All these settings can be set using the PC software.
