The Air Force V Premium employs a sub-platter system consisting of an inner-sub and an outer platter both precision-machined from solid aluminum alloy A5056, with a total weight of 7kg. The outer platter surface is black anodized with a gloss hairline finish that matches with the silver aluminum plinth. It features a tapered spindle and a “very thin” pad of anti-vibration material applied on top.

The table also offers a 2-channel torque switching circuit that adjusts torque until the rated speed has been achieved. Once the rotation speed is achieved, torque is decreased in order to reduce vibration. A DDS (Direct Digital Synthesizer) serves to digitally synthesize any waveform or any value of frequencies according to the output from the crystal oscillator
