SE ELECTRONICS REFLEXION FILTER PRO is an anti-reflection filter for microphone recordings that promotes acoustic isolation and allows a “dry” recording of a vocal part or an instrument. The filter consists of 6 layers: the first is an internal aluminum grid that allows sound to pass through a layer of absorbent wool, and then passes back into an aluminum layer that helps dissipate energy by interrupting the waveforms of low frequencies, and then passes into a space of air maintained as such by the rods that cross the various layers. The air then passes through another layer of absorbent wool and through a second aluminum grid (visible externally
).
