Dynamic class uses the Quadra/FX’s dynamics sensing to switch between low and high rotor speeds. The
Threshold range is the same as with the Gated classes; it can be set in 1-dB increments, from 1 to 30 dB
below full-scale. The Dynamic Rotary effect normally runs at its low speed. When the input signal crosses
above the Threshold level, the effect spins up to its high speed until the signal drops below the Threshold,
when it then spins back down to the low rate. If the Threshold setting is preceded by a lower-case r ( ), the
operation is reversed; the rotary normally runs high until the Threshold level is exceeded, at which time it
spins down to its low speed. When the input signal falls below the Threshold level, the effect will spin back
up to its high speed. The amount of time it takes to switch between speeds is set with the Delay (spin up
time) and Decay (spin down time) parameters.
A Threshold setting of

is also available to disengage all dynamics sensing.
