Noise buster – Hello Clarus Concerto Mk2 [$12K], an 8-outlet AC conditioner with application-specific filtering. "Sensitive analogue components benefit from high-permeability common-mode nanocrystalline inductive filtering which virtually eliminates ground-referenced noise without current limiting current or dynamic compression. The four outlets labelled 'Digital' receive power from a combination of differential-mode and common-mode filter circuits designed to suppress HF noise generated by digital circuitry. The two outlets labelled 'High Current' receive power from a common-mode filter engineered to suppress noise as well as deliver large transient currents while reducing conducted interference and mitigating the effects of radiated noise. These filter networks provide effective noise suppression without introducing series resistance or nonlinear behaviour under dynamic load conditions. Newly added oil-filled capacitors improve thermal stability and the long-term reliability of the analogue and high-current circuits."
