L1 Limiter
Limiter in the L1® (applies to all L1 and L1 Pro Models)
- When you are running your L1® at maximum output and you introduce something else like a voice the limiter may kick in to prevent distortion and prevent damage. As a result the the level of the entire system is reduced. The addition of your voice is what is putting the system into the limiting state.
- You may noticing the limiter on the music and not your voice because when you talk or sing the entire level of the system comes down by "x"dB and but your voice level will still be relative to the music based on your mixer setting.
- When you stop talking the limiter disengages and ramps the music back up to the level it was before you started talking. Essentially the limiter releases and allows the audio to come back to max level.
