Reexion Filter Technical Manual U.S Patent 8,191,678 B2 U.S Patent 8,191,678 B2 Reexion Filter Technical Manual

Thank you or purchasing the Reexion Filter portable vocal booth.

The main idea behind this product is to acilitate dry vocal recordings, in other words

to achieve a vocal recording which has greatly reduced room ambience. O course, the

same Reexion Filter can be u sed to achieve similar results whilst recording various live

instruments, or isolating vocals in rehearsal studios and probably a host o things we

havent thought o yet too! Wed be very interested to hear about novel applications romyou, 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 inormation we can supply to other sE users.

Your Reexion Filter carries a 2 year manuactur ing warranty, with ree replacement o

parts in case o mechanical ailure due to aulty components. This warranty does not cover

ailures deemed to be as a result o misuse or abuse o the Reexion Filter. I properly used

and looked ater, it should last a lietime o recording use.

You can extend your ree 2 year warranty to three years by registering your product

at 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 ew months (dont worry,

we wont pass your details on to anyone else, and we wont bombard you with SPAM!)

One last thing please read this assembly manual to get the best results rom your

Reexion Filter mic positioning, and the stand clamp assembly are critical to getting

best results.

Thank you again, and we look orward to hearing rom you,

The Perfect Position

The perect position to achieve a dry recording is to place the microphone so that the mic capsule sits

centrally (both vertically and horizontally) in relation to the ace o the Reexion Filter (the ace is the

convex side with coloured panels). It is also important to have the mic capsule o the correct distance

rom the ace o the Reexion Filter. The mic capsule should sit roughly level with the ront edges o the

lter where the curved wall ends.

Having said all that, you CAN use the

Reexion Filter to achieve diferent

efects by experimenting with

positioning. Moving the mic into the

ace o the Reexion Filter will give

a darker and more dead sounding

recording, but it will also afect the

polar pattern response o the mic, so

the mic will perorm slightly diferently.

Again, in most cases this would be

undesirable, but this method o use can

create some cool results try micing an

electric guitar cab this way, it can sound

great!

Moving the mic urther away will mean

there is more room ambience recorded

with the dry source. Again, this is not

usually desirable but can be used to

get a specic room sound without the

room taking over completely!

The Reexion Filter can be used not

only or recording vocals and acoustic

guitars etc, but as outlined above, youcan experiment to nd new applications like the guitar cab micing we suggested above. Wed love

to hear rom you with your own novel applications, so please contact us via the main web site, www.

seelectronics.com, to let us know what you think o the product, and how you are using it.

Thanks again, and we hope you enjoy the results o your new Reexion Filter!

3. Fix the support rod to the Reexion Filterby screwing it into the socket on the bottomedge. Tighten the nut using the spannersupplied in the box.

4. Fix the support rod, with theattached Reexion Filter, bypushing the support rod downinto the socket on the stand clampand tighten it in place with theturning key on the block.

5. You can now play with the positioningo the mic (both vertically and horizontally),and the height o th e Reexion Filter toget the optimum position or recording.

Assembling Your Reexion Filter U.S Patent 8,191,678 B2

What is the Reexion Filter?Our Reexion Filters are basically portable devices or 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 o a variable position stand clamp assembly (xed-position in the case o the IRF

2) which ships with the product. The main unc tion is to help obtain a dry vocal or instrument recording.

This is especially useul in studios without proper acoustic treatment, but can also be used to help record

takes in control rooms, where the perormer also has to operate the recording device, or in rehearsal

studios to reduce ambient noise.

The Technical Bit:Reexion Filter Pro (RF Pro): The Reexion Filter Pro has 6 main layers. The rst o these is a strong layer

o punched aluminium, which difuses the sound waves as they pass through it. The next is a section o

absorptive wool, and then a layer o aluminium oil to dissipate energy and break up the lower-requency

waveorms. From this the sound travels through an air gap, which acts as an acoustic barrier, through a

urther layer o wool and lastly an outer, punched polymer wall, which provides additional absorption

and difusion o the remaining acoustic energy.

The Refexion Filter Pro is also equipped with a main absorber, which comprises o our state-o-the-art

specialist acoustic absorption panels. These are tted to the difuser ace o the Reexion Filter Pro by

means o extended separation rods, and serve to provide urther acoustic dampening and difusion to

the sound waves beore they pass to the main lter.

Project Studio Refexion Filter (PSRF): This model utilises some o the design eatures o the Reexion

Filter Pro, while being more suited toward lower-budget project studios. The PSRF uses an outer

boundary o punched aluminium, ollowed by a thick layer o the same high-perormance absorptive

acoustic breboard thats employed by the Reexion Filter Pro. Finally, the inner surace is lined with

high-density acoustic crystal oam with a curved, undulating surace or maximum difusion.

All o the above Reexion Filters are supplied with an adjustable, heavy-duty clamp or attaching to your

microphone stand. Each clamp will accommodate any shock-mount with a standard tting, and support

the Reexion Filter itsel.

Instrument Refexion Filter 2 (IRF2):The IRF2 operates on the same principles as the other Reexion

Filters, but is designed specically with instruments and end-re microphones in mind. It con sists o an

outer layer o punched aluminium much like the other Reexion Filters but then has three discrete

layers o high-perormance absorptive acoustic breboard, each separated by an air gap. Together, these

orm a highly protective acoustic shield, ofering a degree o isolation to the microphone rom other

nearby sources. It is especially useul in drum micing. The microphone is tted and adjusted by means

o a central, rubber-coated clamp, and the entire assembly attaches to your microphone stand by means

o a simple clamping bracket.

1. Remove the Reexion Filter and stand assemblyunit rom the packaging. Please keep thepackaging sae to store the Reexion Filterwhen not in use, or or transportation. It isrobust, but parts may get damaged or lost in

transit i not packaged properly.

You should have the ollowing parts Reexion Filter (curved wall), s tand assembly,support rod and spanner to t support rod.

2. Fix the stand clamp assembly in placeon the neck o your microphone standa ew inches below the point wherethe shock mount is usually xed, oron the main vertical support strut othe stand.You will see the assembly has twoblack blocks with one l arge screw, on thisis a turning key, turn this until theclamp is securely xed to the mic stand.

The clamp also has a large barrelledhinge (with a turning key) which allowsthe mechanism to turn back on itsel sothat the centre o gravity is kept overthe mic stand rather than in ront o it.

This should be hinged ully back so thewhole assembly is in balance, and the RFis then positioned as close to the centreo vertical on the mic stand as possible.

Clamp Assemblies

IRF2 - Specic Brief Fitting Instructions

1. Remove your IRF2 rom its packaging. We recommend keeping the

packaging, in order to transport the IRF2in the uture without risking

damage.2. Remove the protective oam bung rom the central microphone clamp,

in the ace o the IRF2.

3. Fit your microphone. To do this, insert your microphone to the required

position, and tighten or loosen the adjustment screw until the

microphone is secure.

4. Fit the entire assembly to your microphone stand. Adjust the bracket at

the rear o the IRF2 until it is at the desired angle (using the turning key on the adjustment hinge),

then position the microphones boom arm in the large clamp and tighten until its secure.

5. The bung can be inserted i a side-re microphone is being used.

PSRF Clamp Assembly

The Project Studio Reexion Filter (PSRF) clamp operates much like the

Reexion Filter Pro (RF Pro) clamp, but is simpler as the PSRF is a lighterproduct. The stand assembly or the RF Pro comprises a microphone

stand clamp tting, which attaches by means o an adjustable vertical

rod to the horizontal bar assembly. The Reexion Filter itsel, and any

standard tting shock-mount, can be tted to this. The microphone

(in its shock-mount) can then be moved both back-and-orth (PSRF and

RF Pro) and vertically (RF Pro only) along the bar, and the Reexion Filter

itsel can be moved vertically to obtain the optimal working position.

RF-X Clamp Assembly

The RF-X clamp is very simple to assemble. The clamp is tted with a small

threaded piece that attaches the clamp to your microphone stand. It is

recommended that you attach the clamp to your stand rst. The lter isthen xed to the vertical section using the two bolts supplied. These can be

loosened at any time to adjust the height o the lter. Finally, attach your

microphone clip or shock mount to the remaining vertical bar. This can also

be adjusted at any time to vary the position o your microphone within the

lter.
