sE Electronics RF PRO

The Reflexion Filter PRO from sE Electronics is a reflection filter designed to mitigate the acoustic conditions prevalent in home studios. Traditionally, acoustical treatments have been expensive propositions, requiring extensive testing and construction on various surfaces. With the advent of project and small satellite studios, innovative techniques have surfaced to deal with the economics and practicality of treating those acoustic situations.

The Reflexion Filter Pro aims to address this issue by providing a curved baffle made of six different layers (plus an air barrier); the filter is positioned behind any microphone by means of a variable-position, stand clamp assembly. This reduces the amount of acoustic energy hitting any untreated walls, in addition to which, less of the original source is reflected back to the microphone as unwanted room ambiance.

The unit is portable, allowing the user to bring their own acoustical treatment to any environment. The included mounting setup attaches to any microphone stand and provides a sufficient degree of flexibility for adjusting both the position of the microphone and the filter. Recommendations for use include applications for vocals, horns and reeds, guitar, voice-over, percussion, and live location microphones.
