Is the Alfa-Spid stepper motor based? Certainly the feedback is digital. But I could certainly imagine a bunch of fast steps sounds like a beep.
My G5500 actually makes a slightly odd noise too. I sounds almost like a clock being wound. I'm guessing it has something to do with the brake?? Does the A-S have one?
Maybe sound insulation is going to be your best bet.

I do not own one but looking at the documentation for the controller I noticed this, "gradual startup and shutdown of rotor power to reduce stress on towers, antennas and rotors. This is achieved by pulse-width-modulating the operating voltage for the rotor."
That could very well be the source of the "beeping" with the windings in the motor singing.
