switched to Softcomp mode, the yellow LED is On when the signal is in the softcomp region.
Note: Even though no input signal is being applied, it is normal for the LEDs to flicker when the power is applied or removed.

In Har

which fall below this level will pass through the A 5360 unprocessed (except for fixed gain changes directed by the

distinct point at which processing begins, and the THRESHOLD setting corresponds to a point on the input/output transfe
curve midway between the onset of processing and that point at which the transfer curve corresponds to the setting of the
