I agreed, nearly all of the audiophile footers that I see are nearly impossible to adjust levelling once you put them under heavy equipments! I have no idea how well these footers isolate, but at least they let you adjust levelling relatively easily!
With two motors, both are positioned opposite each other. Of course, a perfectly aligned setup is extremely important here.
Naturally, in the Quantum Drive, only one of the two motors (the master) will process the data from the Hall sensor and then transmit it to the slave as well.
Both motors are connected to the same main unit.
It is a high-torque DC motor with sintered plain bearings.
