OP81 OPTO LIMITER
Series 81
The LAA Custom OP81 LEVELING AMPLIFIER OPTO LIMITER is a dynamic limiter built around a custom made optoisolator.
As a limiter it reacts only to the peak signal and let the player able to manage the full dynamic response up till the set threshold.
You can still play light, and clean your crunch with your guitar volume pot!
The OP81 circuit is made by two separate sections: the signal chain where the opto limiting circuit act for reduce the peaks and the Sidechain that drives the electro-optical attenuator system that allows instantaneous gain reduction with no increase in harmonic distortion.
When you reach the intervention threshold setted by the PEAK REDUCTION knob, the OP81 gentle limits your peaks with three selectable RATIO levels.
Decay time set how long the OP81 reduction circuit will work after the fist activation and you are able to manage single notes (short decay) or strumming (long decay).
The small led under RATIO switch show you when the Reduction circuit is working and for how long it works.
