sE Electronics Reflexion Filter Pro Portable Vocal Booth

Cut room ambience in any untreated location, with the portable SE Electronics Reflexion Filter Pro -- perfect for tracking vocals or acoustic instruments.
The Reflexion Filter is basically a portable device for recording live sound sources with reduced room ambience. It is an advanced composite wall which is positioned behind any microphone by means of a variable position stand clamp assembly 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

The Reflexion Filter has 6 main layers. Firstly, a strong layer of punched Aluminum which allows sound waves to pass through it, diffused, to a layer of absorptive wool. The sound waves then hit a layer of Aluminum 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, Aluminum wall which further serve to absorb then diffuse the remaining acoustic energy.

The main absorber has 4 formed pieces of state-of-the-art specialist acoustic absorptive material attached to its face via the extended separation rods, which further serve to absorb and then diffuse read more the sound waves as they pass to the main filter.

The stand assembly 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 Does it 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 un-treated 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, it's a very clever and desirable piece of kit. It allows you to record vocals, guitars etc with a "drier" sound without having to have an acoustically treated room. It's portable. It uses state of the art materials. It works -- and it's a fraction of the price of acoustically treating your studio environment!

"Buy it!"
Verified Customer zZounds has verified that this reviewer made a purchase from us.
I use to spend a lot of time mixing my vocals trying to get the sound I was looking for. Every time I turned the volume up I'd get lots of background hissing and unwanted reverb. Long story short this is the best product out there for vocals. If you have a home based studio you need this. It makes all the difference in your recordings along with a decent mic! The only issue I have with it is the weight of it, your going to need a sturdy mic stand I recommend a tri pod mic stand.
