SE Electronics Instrument Reflexion Filter is ideal for controlling the acoustic space around instruments when recording. SE Electronics Instrument Reflexion Filter was designed on the same principles as its bigger brother, the Reflexion Filter. Instrument Reflexion Filter forms a small curved wall of punched Aluminium, with 3 layers of polyester fibreboard separated with air gaps, which helps reduce room ambience and isolates the mic from ambient noise.
SE Electronics Instrument Reflexion Filter, or IFR, has a hole punched through it to allow a pencil mic, or Shure SM57, etc. to be fixed through it, especially useful when close mic'ing drums to help with separation. The SE IFR is ideal for use with pianos, drums and wind instruments, whereas its bigger brother the Reflexion Filter (RF) is designed for vocal and acoustic guitar applications.
