Royer Labs PS-101 is a metal pop filter with an adjustable gooseneck, manufactured for Royer by Stedman Corporation — the same company that developed and patents the Proscreen filter design. The fundamental difference between the PS-101 and conventional nylon mesh pop filters is the operating mechanism: the louvered metal screen does not diffuse or absorb plosive energy — it deflects the airflow downward, away from the microphone capsule. Sound passes through the large openings in the screen without interference or coloration. A nylon mesh filter always absorbs some acoustic energy in the process; the metal Proscreen does not. The PS-101 can be washed with soap and water and will remain functional for many years — which cannot be said of nylon mesh, which stretches and degrades over time.
Metal louvers — deflection instead of diffusion
The key to the PS-101's operation is the patented expanded metal screen with angled louvers: when a vocalist produces a plosive consonant (P, B), the rapid burst of air strikes the angled louvers and is redirected downward, never reaching the microphone capsule. The vocal sound — as an acoustic wave rather than an airstream — passes through the open screen geometry without attenuation or tonal modification. The result is plosive protection with no loss in tonality, detail, or transient response — particularly important with Royer ribbon microphones, whose character is sensitive to any modification of the signal path upstream of the element. The 13-inch gooseneck with vinyl noise-reduction covering and a clamp with a nylon tip protecting the stand finish allow precise positioning at any source. Royer Labs has issued an official technical bulletin warning against counterfeit PS-101 units lacking the genuine angled louvers, which function no differently than a standard nylon filter.
