announce a small format portable isolation screen and acoustic absorber for better instrumental recording,
the Instrument Reflexion Filter (IRF).
The Instrument Reflexion Filter (IRF) is
designed on the same principles as its sibling the Reflexion Filter. It forms a small curved wall
of punched Aluminium, with layers of polyester fibreboard separated with air
gaps, which helps reduce room ambience and isolates the microphone from ambient noise.
The Instrument Reflexion Filter has a hole punched through it to allow a pencil
mic, or SM57 to be fixed through it. This is useful for recording close to an instrument
to aid track separation in your live recording session. Please note that the
1.125" diameter mounting hole is not suitable for large microphones. The
Instrument Reflexion Filter (IRF) is ideal for use with individual percussion
instruments, guitar amplifiers, pianos, drum overheads and wind instruments,
whereas the original Reflexion Filter is used primarily for vocals.
The main function is to help obtain a ‘dry’ instrument recording. This is
especially useful in a project studio without proper acoustic treatment, but can
also be used to help record in control rooms or in rehearsal studios to reduce
ambient noise.
The Technical Bit:
The Instrument Reflexion Filter has layers. Firstly, a strong layer of
punched Aluminium which allows sound waves to pass through it, diffused, to a
layer of absorptive wool. The sound waves then hit a layer of Aluminium foil
which helps dissipate energy and break up the lower frequency wave-forms, and
from here they hit an air space kept open by rods passing through the various
layers. The air gap acts as an acoustic barrier. The sound waves then pass to a
further layer of wool and then through an outer, punched, Aluminium wall which
further serve to absorb then diffuse the remaining acoustic energy.The various
layers both absorb and diffuse the sound waves hitting them, so progressively
less of the original source acoustic energy passes through each layer. This
reduces the amount of energy hitting un-treated walls and other surfaces so
there is less of the original source reflected back as unwanted room ambience to
the mic. Simple, effective and the work of a British company (well done
James).
Summary
The Instrument Reflexion Filter from sE Electronics is a smaller version of their Reflexion Filter, designed specifically for instrument recording. The Instrument Reflexion
Filter is a perfect solution for recording environments that are less than perfect,
reducing room reflections and unwanted ambiance and thus can help you to create
tighter, punchier, and more detailed recordings.
