Primacoustic VoxGuard VU
Nearfield Absorber Portable Acoustic Shield
The Primacoustic VoxGuard is a portable acoustic screen designed to reduce the ambient noise around a microphone when recording. This helps to eliminate excess echo and reverb, allowing the engineer to reintroduce the desired effects during mixing or post-production.
The VoxGuard features high-density open cell acoustic foam that provides maximum absorption throughout the vocal range.
An extra large high impact ABS outer shell keeps unwanted noise out, while innovative slotted ports prevent excess bass buildup and resonance commonly associated with stand-mounted absorbers.
Once mounted, a rear access cable port allows any hand held or studio microphone to be articulated and directed at a specific source.
The VoxGuard has been updated and now features a window that allows the vocalist to maintain visual communication between the engineer, producer or other band members.
Unlike other similar offerings that employ heavy and cumbersome steel parts, the VoxGuard is lightweight and easy to use.
The outer shell simply slides over the threads of the microphone stand and is held in place by the clip, shock mount, or included threaded adaptors.
For additional flexibility, an extension bar is included for infinite mic placement possibilities.
The lightweight design and simple mounting hardware makes positioning the VoxGuard easy without the usual fear of the stand falling over and damaging the microphone.
Thanks to its simple and lightweight design, the VoxGuard can also be used as a portable acoustic gobo in front of amplifiers, acoustic instruments, or anywhere that basic isolation is required.
This makes it and ideal tool for recording studios, film and television, pod casting, and mobile recording.
The VoxGuard is a nearfield vocal screen designed to reduce the ambience around a microphone when recording. This allows the voice to be captured while eliminating the echo and reverb, allowing the engineer to reintroduce the desired effects during post production.
The VoxGuard is unique in that it is larger than competitive products while being lighter. This makes it more stable on the mic stand and opens the door to a wide array of applications including shielding instruments from each other in the studio; as a desk top acoustic shield for pod casting and is able to be used with all types of mic stands.
The VoxGuard attaches to a mic stand with the supplied threaded mic stand adaptor. An open slot allows the cable through the back side while allowing the microphone to be articulated for optimum positioning.
The VoxGuard is a simple device that employs well known acoustic principles to minimise room ambience from entering the microphone. This allows a greater percentage of the source to be captured without the echo, reverb and resonance from the room.
Once the ‘dry recording’ is on tape, artificial ambience in the form of digital reverb, echo and EQ is then added.
The science behind the VoxGuard is simple.
It combines absorption by way of high density open-cell foam with an acoustic shield to prevent ambient sound from entering the mic. This page explains the science behind the design.
Eliminating The Sound Of The Space
Put up a microphone in a room and hit ‘record’. The sound of the voice will compete with the sound echoing off the walls.
These are known as primary reflections, flutter echo and standing waves. These will invariably arrive at the microphone after the original sound and depending on how loud they are, will cause varying degrees of phase cancellation known as comb-filtering.
Although in some cases one may want to record using the natural room’s effect, today it is common practice to record a dry vocal track and only add artificial ambience during the mixing phase.
Most engineers prefer to work this way, as committing to room ambience early-on usually conflicts with the instruments and limits options.
The VoxGuard Design
With acoustics, one can either absorb sound or reflect it.
The VoxGuard performs both functions at the same time.
First, when singing into the microphone, sound is captured by the mic while a good percentage of sound breezes by. In space, this ‘extra’ sound would go forever without echo as there are no boundaries. In an anechoic test chamber, sound is completely absorbed as there are no hard reflective surfaces.
In this case, the VoxGuard’s high density open-cell acoustic panel absorbs much of the energy in the critical voice range.
What spills over is then spread into the room. This echoes around in the form powerful primary reflections and flutter echo that create the room’s reverberant field.
The VoxGuard’s curved outer shield is designed to reflect unwanted energy away while the larger size—upwards to twice as big as others —reduces flanking.
This effectively creates a boundary that stops sound from coming back into the mic, reducing the ambient effect.
The result is predictable: With more of the original source and less of the reverberant field, the recording engineer is better able to control the sound of the voice or instrument to best fit the recording.
How to Use
The VoxGuard is a simple device designed to control the ambience around a microphone.
The usual setup is to place the VoxGuard onto a mic stand using the threaded adaptor that is supplied to hold the VoxGuard in place. The microphone is then attached onto the threaded attachment using a mic clip.
Large diaphragm studio mics
Large diaphragm studio microphones are generally very sensitive to sound and noise. Therefore they are normally used with some form of shock-mount or suspension. This eliminates noise such as foot tapping from transmitting from the floor through the mic stand and into the microphone.
The VoxGuard is ideally suited for this type of microphone. Merely attach the shock-mount to the threaded adaptor and you are set to go. Because the microphone and the VoxGuard will be relatively close to the centre of gravity, the stand should remain very stable.
Hand held microphones
For added flexibility, the VoxGuard has been designed with a cable access slot to allow typical dynamic microphones such as a Shure SM58 or Sennheiser MD421 to be used.
Begin by attaching the mic clip to the knurled threaded attachment. Then, bring the microphone cable through the access slot and connect to the microphone. The access slot has been designed in such a way that the microphone can still be articulated so that it can move up or down to suit.
This makes setting up the VoxGuard mush more efficient.
Using the VoxGuard for post production
When recording voice over tracks, it is often preferred that the tracks be completely void of any room ambience. This allows the engineer to add in reverb, echo or darken the track to suit the movie set.
An easy way to further reduce room ambience is to have some form of acoustic treatment behind the voice talent. This can be an acoustic panel or even a suspended blanket situated 1 metre behind the microphone.
How does the VoxGuard work?
Ambient room attenuators like the VoxGuard work by attempting to eliminate as much of the room ambience as possible so that the microphone only captures the sound of the voice. This allows the engineer to introduce effects such as reverb or echo during the production phase.
You say the VoxGuard is larger. Why does this matter?
Yes. The VoxGuard is up to twice as large as competitive products. The larger the absorptive area you can create around the microphone, the greater the absorption you will enjoy and less of the ambient noise will enter the microphone from flanking.
Can you explain flanking?
Flanking is a term used by acousticians that refers to how sound will come over an acoustic divider or boundary and wrap around it.
By increasing the size of the divider, you make the boundary more difficult for unwanted sound to flank. Today, highways are often flanked with walls designed to keep traffic noise contained. Some have reflective shields that angle inward towards the traffic to further reduce flanking.
The VoxGuard employs the same scientific approach.
Does weight matter with a near-field absorber?
Increasing weight by increasing the density of the acoustic panels will generally improve the low frequency absorption. Thus the reason we employ high density open cell acoustic foam.
But as anyone who has some technical background knows, deep low frequencies have long wavelengths that are both omnidirectional and generally more powerful than high frequencies. This means that they will generally pass through or go around most devices and will be almost impossible to control.
As such, the VoxGuard is intended to control the voice range, not bass.
Is the VoxGuard Stable? I have seen others fall down and damage the microphone.
When we set about to improve the designs that are already on the market, the first thing we wanted to do was address the problems that many have encountered such as the heavy metal fittings that are impossible to tighten and often cause the microphone stand to become unstable.
We started by eliminating any unnecessary weight from the absorptive shield. Then we balanced the VoxGuard shield so that the centre of gravity would be work with a typical recording microphone.
Not only is it significantly more stable than the competition, because of the light weight, the VoxGuard is able to be employed in many more applications.
Other brands use metal, does this help?
They look cool and give you the impression that they are technically advanced. We feel that form, function and performance are more important than visual appeal.
