Designed pairs of suspension pins into the CNC aluminium frame of the N3Ultra, the JAN6418 is hanged vertically with a suspension effect. Integrated with the body frame, achieving multi-directional stress relief for the tube's filament. Enhance stability by introducing an appropriate amount of inter-stage loop NFB to inhibit the closed-loop gain.
