ABSORBENT SCREEN FOR MICROPHONE Anti-reflection filter - 7 vertically arranged bass traps - Holed aluminum diffuser - High-end acoustic absorber - Polycarbonate diffuser - Insulating air gap. It is a filter that does not change the tonality of the voices at all. It is the most appropriate thing I have found when you need to have consistency in everything recorded, but at the same time you have to go recording in different environments, which happens when you record while on tour. Just level and correct the acoustics wherever you need to record. Scott Hendrix, producer for Blake Shelton, Faith Hill, Trace Adkins, Alan Jackson, Brooks & Dunn. If you are recording vocals at home, you need a Reflection Filter without fail. Weight: 2.6 Kg. Measurements: 450 x 330 x 250 mm
