This is 5 pieces of the sE Electronics IRF in a full flight case for touring drummers, orchestral applications and Pro studios with multiple instrument miking applications.
The Instrument Reflexion Filter is designed on the same principles as its bigger brother the Reflexion Filter.
It 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.
The IRF has a hole punched through it to allow a pencil mic, or SM57 etc to be fixed through it, especially useful when close miking drums (to help with track separation) or overhead miking.
The IRF is ideal for use with pianos, drums and wind instruments, whereas the RF is used for vocals and guitars.
