Thank you for buying the sE Electronics Instrument Reexion Filter.
Although the main idea behind this product is to facilitate ‘dry’ and ‘separated’ instrument recordings we’d
be very interested to hear about novel applications from you, so please do contact us with your ideas; we
are always glad to listen as it helps us improve and develop the product, and the information we can
supply to other sE users.
Your Instrument Reexion Filter carries a 2 year manufacturing warranty, with free replacement of parts in
case of mechanical failure due to faulty components. This warranty does not cover failures deemed to
be as a result of misuse or abuse of the Instrument Reexion Filter.
You can extend your free 2 year warranty to three years by registering your product at
www.seelectronics.com <http://www.seelectronics.com/> so please visit the site and leave your details.
You can also subscribe to the sE newsletter which we email out once every few months (don’t worry, we
won’t pass your details on to anyone else, and we won’t bombard you with SPAM!)
How it works
The sE Instrument Reexion Filter or IRF works on the same principle as our highly acclaimed Reexion
Filter, which was initially developed to assist in vocal recording. The Reexion Filter system works in two
ways: by shielding the rear and sides of the microphone from o-axis sound, such as room reections,
and by reducing the amount of vocal sound spilling out into the room. In most small studios, the room
reections often colour the sound in a destructive way that is impossible to remedy using EQ or by adding
additional articial reverb, so minimising these reections at the recording stage makes it possible to
achieve professional sounding recordings in an acoustically imperfect room. In reality the Reexion Filter
acts as a localised recording booth that eliminates the need to treat the entire room. Our unique multi-
layer absorber technology allows the Reexion Filter to be made much more compact than acoustic foam
or mineral wool panel absorbers oering a similar level of performance and our new Instrument Reexion
Filter takes this well proven concept and adapts it for instrument use.
The SE Instrument Reexion Filter is a scaled down version of the original with a versatile gooseneck
mounting system and a central tube to allow ‘end re’ microphones, such as the SE2A, to be set back into
the IRF so that the acoustic screening can work as eectively as possible.
Measuring 6.5 inches by 8 inches, the IRF is light enough to be supported on a conventional microphone
stand using the clamp assembly at the end of the gooseneck. The gooseneck is packed with the IRF but
not xed to it. A simple thumbscrew system holds this in place but take care not to lose the bre washer
as this helps keep the joint tight.
