The black RF-PBO-16 Premium Reflection Filter from Auray is constructed with rugged ABS plastic and employs high-density open-cell acoustic foam to absorb unwanted ambient noise and control acoustic reflections. It can be used by music producers, engineers, and broadcasters in recording applications for vocals, voice-overs, or podcasts, in a studio or acoustically untreated space. The filter's high-density open-cell acoustic foam absorbs sound, and its additional inner-acoustic layers combine for isolation with near-zero coloration. The vented shield creates a more open sound while it prevents bounce-back reflections. Additionally, the RF-PBO-16 is compatible with most 5/8" mic stands and shockmounts, and works in an inverted position with a mic stand or a studio boom.
