Reflexion Filter Technical Manual
Clamp Assemblies
This varies between our products. The IRF has a simple stand clamp which can be fixed to a mic
stand, drum hardware etc.
The Baby RF (PSRF) clamp operates much like the RF clamp, but is simpler as the Baby RF
is a lighter product. The stand assembly for the RF Pro comprises a mic stand clamp fitting,
which attaches by means of a vertical joint to the horizontal bar assembly onto which both
the Reflexion Filter, and any standard fitting shock mount can be fixed. The microphone (in
its shock mount) can then be moved both vertically and horizontally along the bar, and the
Reflexion Filter itself can be moved vertically to obtain the optimum working position.
How do they work?
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 untreated walls and other surfaces so there is less of the original source reflected
back as unwanted room ambience to the mic. The Reflexion Filter also helps prevent any
reflected sound reaching the back and sides of the mic. Its shape and size have been carefully
tested to maximize absorption while keeping ‘coloration’ down to only around 1dB, and leaving
the microphone’s polar pattern unaffected.
In summary:
All in all, these are very clever and desirable pieces of kit. They allow you to record vocals, guitars
etc with a ‘drier’ sound without having to have an acoustically treated room. They are portable,
use state of the art materials; they work and are only a fraction of the price of acoustically
treating your studio environment!
