Limiter action:
Apply the necessary attenuation on a specific channel only when the signal amplitudes on that specific chan-
nel rises above LMAX.
Remove attenuation on a specific channel only when the signal amplitude on that specific channel falls below
CUSH.
Apply the necessary attenuation on BOTH channels when the signal amplitudes on any ONE channel rises
above LMAX.
Remove attenuation on BOTH channels only when the signal amplitude on BOTH channels fall below CUSH.
