SE Electronics Reflexion Filter Pro, The Reflexion Filter is basically a portable device for recording live sources with reduced room ambience. The main function is to help obtain a ‘dry’ vocal or instrument recording. This is especially useful in studios without proper acoustic treatment, but can also be used to help record takes in control rooms, where the performer also has to operate the recorder, or in rehearsal studios to reduce ambient noise, Dimensions: 390 x 200 x 320 mm
