Reviews: low shelf EQ, controlled by klvl and kS (kQ is ignored by this filter type...The kS parameter controls the steepness of the slope of the frequency response (see below...a higher value means a steeper slope, with resonance if kS > 1 (however, a too high kS value may make the filter unstable...Note that the effect of kS - especially if it is greater than 1 - also depends on klvl, and it does not have any well defined unit...
