Pro Audio Power Cleaner

Engineered for professional and high-fidelity audio applications, this Level 3 power filter accepts 110–250 V AC input and delivers filtered AC output at matching voltage, rated for 10 A continuous load. Its core is a high-density PCB loaded with precision passive components, enclosed in a black housing. Input uses a 3-wire 7.62 mm socket (live, neutral, protective earth); output uses a 2-wire 7.62 mm socket (live, neutral). The input GND terminal offers installation flexibility: connect to mains earth or to the local chassis — enabling tailored grounding schemes to minimise noise coupling in complex audio systems. It implements a rigorously segmented filtering architecture: Stage 1 handles differential-mode noise via two matched inductors; Stages 2 and 3 apply sequential common-mode filtering using X2 capacitors and high-alignment common-mode chokes. This triple-stage topology provides exceptional attenuation of fast, repetitive transients — particularly those in the 2–10 kHz band — commonly introduced by modern lighting, HVAC controls, or shared building infrastructure in UK residential and studio spaces. When deployed ahead of power amplifiers or digital audio endpoints, it purifies the supply by eliminating DC offset, suppressing transformer-induced mechanical resonance (buzz), and scrubbing high-frequency switching noise — translating directly into improved signal-to-noise ratio, tighter bass definition, and heightened realism in vocal and instrumental timbre — benefits confirmed by technical measurements and user reports from UK-based audio integrators.
