3. Fix the support rod to the Reexion Filter
by screwing it into the socket on the bottom
edge. Tighten the nut using the spanner
supplied in the box.
4. Fix the support rod, with the
attached Reexion Filter, by
pushing the support rod down
into the socket on the stand clamp
and tighten it in place with the
turning key on the block.
5. You can now play with the positioning
of the mic (both vertically and horizontally),
and the height of the Reexion Filter to
get the optimum position for recording.
Assembling Your Reexion Filter U.S Patent 8,191,678 B2
What is the Reexion Filter?
Our Reexion Filters are basically portable devices for recording live sound sources with reduced
room ambience. All three models use an advanced, multi-layer wall which is positioned behind any
microphone by means of a variable position stand clamp assembly (xed-position in the case of the IRF
2) which ships with the product. 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 recording device, or in rehearsal
studios to reduce ambient noise.
The Technical Bit:
Reexion Filter Pro (RF Pro): The Reexion Filter Pro has 6 main layers. The rst of these is a strong layer
of punched aluminium, which diuses the sound waves as they pass through it. The next is a section of
absorptive wool, and then a layer of aluminium foil to dissipate energy and break up the lower-frequency
waveforms. From this the sound travels through an air gap, which acts as an acoustic barrier, through a
further layer of wool and lastly an outer, punched polymer wall, which provides additional absorption
and diusion of the remaining acoustic energy.
The Reexion Filter Pro is also equipped with a main absorber, which comprises of four state-of-the-art
specialist acoustic absorption panels. These are tted to the diuser face of the Reexion Filter Pro by
means of extended separation rods, and serve to provide further acoustic dampening and diusion to
the sound waves before they pass to the main lter.
Project Studio Reexion Filter (PSRF): This model utilises some of the design features of the Reexion
Filter Pro, while being more suited toward lower-budget project studios. The PSRF uses an outer
boundary of punched aluminium, followed by a thick layer of the same high-performance absorptive
acoustic breboard that’s employed by the Reexion Filter Pro. Finally, the inner surface is lined with
high-density acoustic “crystal” foam with a curved, undulating surface for maximum diusion.
All of the above Reexion Filters are supplied with an adjustable, heavy-duty clamp for attaching to your
microphone stand. Each clamp will accommodate any shock-mount with a standard tting, and support
the Reexion Filter itself.
Instrument Reexion Filter 2 (IRF2): The IRF2 operates on the same principles as the other Reexion
Filters, but is designed specically with instruments and “end-re” microphones in mind. It consists of an
outer layer of punched aluminium – much like the other Reexion Filters – but then has three discrete
layers of high-performance absorptive acoustic breboard, each separated by an air gap. Together, these
form a highly protective acoustic “shield”, oering a degree of isolation to the microphone from other
nearby sources. It is especially useful in drum mic’ing. The microphone is tted and adjusted by means
of a central, rubber-coated clamp, and the entire assembly attaches to your microphone stand by means
of a simple clamping bracket.
