- Short term ( - The threshold of this limiter is automatically trimmed by an instantaneous impedance measurement when the amplifier goes out of standby. This automatic adjustment ensures that the threshold does not exceed the rated power or the maximum current that the amplifier can deliver. In low impedance LUCIA models, alternate presets may be used that designed for a lower power output than the full output allowed by the default preset.
- Medium term limiter - This limiter is inserted to avoid clipping if the power supply rail sags.
- Long term (>0.5 s) - This limiter is inserted to prevent thermal problems.
Following is a simplified description of the LUCIA limiters:
