Description
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 SPL limiters are not peak limiters, the dynamics of the music are not affected. The SPL2 limits based on the incoming audio at the line input and thus does not use a measuring microphone like the more elaborate models.
Both input sensitivity (threshold) and output attenuation (output level) can be set on the SPL2. All connectors and the controls can be sealed after installation, so they cannot be adjusted afterwards.
