To the reference in 1., as the beater angle setting works conjunctively in your bass drum pedal, it is the setting of the magnets’ alignment/spacing that create your pedal’s over all feel and performance. As the magnets meet face to face the magnetic field of repulsion is at its greatest. Offset, it is less intense. The slide adjust feature in the pedal board allows alignment increase or decrease of the magnetic field. Loosen the set bolt and slide the pedal magnet up or down to give you that range of repulsion adjustment, up giving the strongest.
After the initial settings of beater angle/height and upper cartridges use the slide adjust for the final fine tuning you want.
For reference purposes, the right and left sides are as such when looking down at your pedal with the Drumnetics™ logo facing you. The two top cartridges are affixed to the cam side plates and do not feature any adjustment. The two bottom ones are attached rotationally on the axle shaft and allow repulsion settings that coincide with the fixed, top cartridges as you play the pedal.
